This session demonstrates that "Agility" and "SOA" complement each other quite well. Just because SOA is buzz-word compliant doesn't mean that you should throw good practices out the window. This session demonstrates how you can apply the principles of agility to building highly complex distributed enterprises.

Managers and ivory tower architects seem to think that all the rules that apply to "normal" software don't apply to SOA. Ironically, they matter even more. Agility and SOA are closely aligned because SOA is about building complex distributed systems and Agility is about effectively building complex software. This session unveils the pillars of successful SOA and how to achieve them in a testable, iterative fashion. It discussing testing strategies, how to make your architecture more robust and maintainable, and how to design an evolutionary architecture.

Most developers think that "TDD" stands for Test-driven Development. But it really should stand for "Test-driven Design". Rigorously using TDD makes your code much better in multiple ways.

This session demonstrates how stringent TDD improves the structure of your code. I discuss TDD as a technique for vetting consumer calls, using mock objects to understand complex interactions between collaborators, and some discussions of improved code metrics yielded by TDD. This session shows that TDD is much more than testing: it fundamentally makes your code better at multiple levels.

Developers from the 1980s would be shocked at how inefficiently developers use their computers because of the advent of graphical operating systems. This talk describes how to reclaim productivity afforded by intelligent use of command lines and other ways of accelerating your interaction with the computer and bending computers to do your bidding. Stop working so hard for your computer!

In The Productive Programmer, I identify 4 principles of productivity: acceleration, focus, automation, and canonicality. This session defines the principles and describes their use, but the primary focus of this talk is on real-world examples of how you can use these principles to make yourself a more productive programmer. Acceleration covers ways to speed up development by taking command of your computer. This includes keyboard shortcuts (including ways to learn them and make better use of them) in both IntelliJ and Eclipse. Focus describes how you can utilize your environment (both physical and computer) to greatly enhance your productivity. Canonicality (the DRY principle from The Pragmatic Programmer) discourages repeating artifacts in projects. This talk shows effective ways to avoid this repetition. I show examples of creating DRY documentation, O/R mapping, database schemas, and development environments. Automation refers to making the computer do more work for you. This talk includes tons of examples, all culled from real-world projects

There's the perfect world, and then there's the world you have to live in. Lots of organizations would like to reap the benefits of Agile development techniques but don't know how to get started. This session discusses the key benefits you can derive from Agile software development so that you can decide for yourself how many agile techniques will work within your organization.

I discuss project planning and estimation, how to benefit from pair programming when you aren't allowed to pair, how to measure your progress, and other project milestones. Agile software development isn't just an unrelated set of activities, it is a discipline. Once you understand the component parts of the discipline, you can apply them to your less-than-agile world.

The Gang of Four book should have been entitled "Palliatives for Statically Typed Languages", because the recipes it provides are cumbersome solutions to the problems it poses. Using powerful languages makes the solutions in the GoF book look hopelessly complicated. This session shows how to solve the same problems concisely, elegantly, and with far fewer lines of code using the facilities of dynamic languages.

The Gang of Four book was actually 2 books: a nomenclature describing common software problems and a recipe book for solutions. The vocabulary they defined is still useful. The recipes are a disaster! Dynamic languages (like Groovy and Ruby) have powerful meta-programming facilities far beyond statically typed languages. It turns out that many of the structural design patterns in the Gang of Four book and beyond are much easier to solve with meta-programming. This session compares and contrasts the "traditional" approach of design patterns with a more nuanced meta-programming approach. Using language features creates cleaner abstractions with fewer lines of code and little or no additional structure. This session shows one of the many reasons that dynamic languages are such a hot topic.

By Neal Ford

What does code + methodology have to do with one another? Everything! Agile projects focus on delivering working code, and tools exist to allow you to verify some quality metrics for your code. This session is a survey of tools and metrics that allow you to determine the quality of your code and strategies to "wire it" into your agile project.

Agile projects focus on delivering code. The responsibility for the quality of that code lies with developers. Yet most developers have a poor sense of how to gauge the quality of code, both during development and forensically. This talk lives on the boundary between what is important in agile projects and ways to verify code quality. It is both a survey of tools and metrics and strategies for proactively applying these techniques to ongoing projects. I talk about the Hawthorne effect, analysis tools (both byte and source code), useful metrics, tools for generating metrics, and how to analyze raw data into actionable tasks.

Session Topics:

• The Hawthorne Effect
• How Agility and Metrics Feed Each Other
• Analysis Tools
• FindBugs
• PMD/CPD
• Testing Metrics
• Cyclomatic Complexity
• Chidamber and Kemerer Object-oriented Metrics
• JDepend
• Code Change Risk Analyzer and Predictor for Java
• Panopticode
• Tools

You are using Java, whew!!! No need to worry about memory, the garbage collector will handle that. Those who have had a memory issue in Java are not so naive any more. Often memory utilization and heap sizes are an after thought and are not recognized until the application is in production, often caused by application uptime, production request volume or production sets of data. When the OutOfMemory Error occurs, often the science of development seems to brake down and knobs are turned. First the (-mx) maximum heap space gets adjusted... More is better right. The next OutOfMemory, heads start scratching, code reviews start in earnest, and Google gets several new hits. Did you know that it is possible to get an OutOfMemory error without running out of heap space?

This talk will walk through the underlying details of memory management in the JVM with a focus on VM flags available to help configure the VM. However we can't configure the VM without a detailed understanding of what is going on inside the VM. We'll focus on tools available for analyzing the memory in a running VM. Two actual client case examples will be presented. We'll discuss the differences between the two cases and why the end configurations were quite different.

A live Hacking demonstration exposing the tools and techniques used by Hackers.

A look at the growing space referred to as ethical hacking or penetration testing. We'll look at example attacks which include: Client-side exploits Sql-Injections Brute force attacks Man-in-the-middle attacks Key logging

By Ken Sipe

Security concerns abound... According to Gartner 75% of all attacks are at the web application tier. There has never been a more urgent time to understand the security concerns and how to apply solutions to our web applications.

This session will look through the details of threat modeling, who should do it and how does it fit into the software development life-cycle.

By Ken Sipe

As you rise through the organization from developer to architect or manager, there are different skills which must be honed in order to maximize your influence. As evident by the open source community, technical leadership is more dependent on influence then it is on authority. This session will focus on skills development, dynamics in a corporate environment and community building.

This session will discuss key interpersonal skills and how they can affect your projects and career. We cover how to positively connect with humans, how to participate in and influence the business processes you support, and how to transcend your technical role and maximize your connections with all members of your organization.

We'll examine the dynamic nature of large organizations – their structures, decision making processes, and political landscapes. We’ll discuss the goals of key business and technical decision makers and their influence on architects and software projects. We’ll conclude with some strategies for maximizing the soft skills to ensure successful outcomes for your projects and career.

By Ken Sipe

Well the standards created EntityBeans.... yea. and the community created Hibernate. Fortunately the standards body learned some lessons and created JPA. JPA requires a vendor implementation and none make a better choice then Hibernate. Combined with Spring this trio is a powerhouse when it comes to developer productivity on applications requiring persistence.

This session will look at in detail the persistence capabilities of the latest Spring 2.5 and how to provide data access capabilities, including nicely added features for unit tests. We'll focus the persistence discussion on JPA and examine a number of ORM mapping scenarios and how JPA maps to them. We'll focus on the spring integration including transactional capabilities.

By Ken Sipe

Spring 2.5 is brand spanking new, with a number of fantastic features. With growth of large and complex Spring applications which struggle with xml manageability and with the added pressure of Guice and SEAM there is a push for less XML, with solution leaning towards annotations. Spring 2.5 adds to the toolset provided in Spring 2.0 to provide a development environment where XML is greatly reduced... or eliminated if you so choose.

The session walks through the new Spring 2.5 enhancements, then dives deep into annotation oriented injection. The demonstrations include standard applications as well as a look at the new Spring MVC.

By Ken Sipe

Thoughts lead to words, words lead to action, actions lead to habits. In this session we'll sharpen the development saw in the process of understanding what makes a hyper-productive programmer. The focus will consist of developer habits and development processes.

As described in the book "7 Habits for Highly Effective People", there are habits which are characteristic of highly effective people. Clearly there are hyper-productive developers which distinguish themselves from the development pack? what is it that makes the difference? What are the habits and practices of highly effective developers?

This session will focus on individual developer habits, as well as team practices and the processes which result in high quality running software.

By Ken Sipe

Scale... what is scale... how do you applications that are scalable. How do you know if the application scales?

This session will look at server topologies and state management and how it affects scale. We'll detail a number of metrics to know and observe. In addition tools of the trade will be demonstrated such as jmeter.

Most people new to Aspect-Oriented Programming (AOP) are fed up with separation of concerns zealots explaining how great their techniques are at dealing with... logging. Ok, you get it. Logging is a cross-cutting concern that can be appropriately modularized. What else does AOP have to offer? A lot, it turns out. This talk will give an introduction to the motivations of AOP as well as a series of concrete examples drawn from enterprise and client side Java. Come learn how AspectJ-flavored AOP can begin to benefit you immediately either in development or production environments. Learn how to enforce architectural policies, find Swing threading issues, reduce the invasiveness of the Observer design pattern or even improve the reusability of your domain models. Now that Spring 2.0 provides support for AspectJ, the time has never been better to learn about these new (but backwards compatible) ways of thinking about building software.

Attendees will learn about
The history and reasons behind AOP
Development-oriented aspects that can be useful, but compiled out of production code
Production-oriented aspects that can simplify development and ease the burden of future changes
Basic AspectJ usage and jargon How to use AspectJ with Spring

Rating: Intermediate
Category: Architecture/Languages, Client Side Java, Server Side Java Prerequisites: Basic Java. Some level of AOP understanding is helpful, but not required. The pace of the introduction will depend on the average level of exposure the audience has previously had to AOP.

How well do you understand the dynamics of your applications? In our systems, we detect when simple things happen. Customers log in, people buy things, a stock is sold at a particular price, inventory shifts locations... all of these events mean little things, but what about the larger picture? Complex events are particular patterns of simpler events that suggest something deeper is happening. Do you know how you'd discover these bigger picture occurrences? Come hear how the Esper open source software represents a new class of complex event processing (CEP) frameworks that can be added to even high volume, high transaction systems.

Trying to write software to track event occurrence is difficult to do correctly and almost impossible to do efficiently. The problem is that the higher volume and performance our systems get, the harder it becomes and the more important it is to highlight interesting or unexpected activity that isn't represented simply by a log entry.

Complex Event Processing (CEP) and Event Stream Processing (ESP) systems are emerging as a new strategy for processing and detecting complex sequences of more rudimentary events that could have bigger implications to your production systems. While commercial software is starting to add this behavior, Esper represents one of the most accessible and widely-used frameworks for adding CEP/ESP capabilities to Java applications.

Just as the world is feeling comfortable with the Web, Tim Berners-Lee et al inform us that what we have seen so far is just the beginning. His original plans at CERN were larger and grander. The Semantic Web is a vision of machine-processable documents and metadata to improve search, knowledge discovery and data integration and management. The only problem is that there is no such thing. There is no Semantic Web, just the Web we have that is increasingly semantics-enabled.

Forget the hype. Come learn how the technologies of this vision are being used today on the Web and in the Enterprise by more people than you might think.

Attendees will learn:

The history and motivations behind the Semantic Web vision An honest assessment of where we are and what is likely to unfold The technology stack involved (including RDF, RDFS, SKOS and OWL) Tools built around this stack Introduction to how they can help you today

By Brian Sletten

There is a shift going on in the Enterprise. While still used and useful, the promises of the SOAP/WSDL/UDDI Service-Oriented Architecture (SOA) stack have failed to live up to their promise. A new vision of linked information is enveloping online and Enterprise users. The REST architectural style is squarely behind this thinking as a way of achieving low-cost, flexible integration, increased data security, greater scalability and long-term migration strategies.

If you have dismissed REST as a toy or are unfamiliar with it, you owe it to yourself to see what is so interesting about this way of doing things.

There is tremendous interest in REpresentational State Transfer (REST) as an architectural style for building scalable, flexible, information-driven architectures in the Enterprise. The success of the Web has caught our attention in the face of increased complexity and many failures with more traditional Web Services technologies. The problem is that it is difficult to sell a way to do things. Managers do not want to feel like they are innovating in the middleware space. They want to understand why they should deviate from the blue prints laid down by the industry leaders. They want to understand when they should use REST, when they should use SOAP and when they might fallback to regular old Java-based messaging. They want to make business-based technology decisions that lay a path to forward progress rather than paying for technological flux.

This talk will introduce REST and walk through why it is so important and makes such a difference. We will talk about REST API design, security, long-lived systems, content-negotiation, contract enforcement, when REST might not make sense, etc.

REST and the Web Architecture are the basis for many exciting things happening on the Web and within our organizations. You owe it to yourself to make sure you really "get it".

This talk should be accessible to everyone but is probably intermediate level.

By Brian Sletten

If you have started to take a look at REST as way of exposing web services or managing information spaces, you may be frustrated by the support offered by legacy containers. There is no direct support for REST concepts in the J2EE specs (yet). XML-based configurations are so 1990's. Come learn about Restlets, a little API that has caught the attention of many in the RESTafarian community.

The Restlet API was created by a guy who wanted object-level support for RESTful concepts, but didn't want to make the move to an advanced resource-oriented environment like NetKernel. He wanted his REST and conventional environments too. He also wanted a path to more modern containers that aren't tied to a blocking I/O model like the Servlet spec is.

This talk will include a brief review of REST and its primary concepts and will then provide an introduction to the Restlet API and how it supports these ideas. It will then focus on standing up a REST-oriented infrastructure using the Restlet API and a variety of other open source tools to support a publish/find/bind infrastructure without touching SOAP/WSDL/ or UDDI.

This talk will not try to convince you about using REST. If you aren't familiar with the concepts or want convincing, please come to the "REST" talk first.

Prerequisite: REST (unless you are very comfortable with REST)

By Brian Sletten

Imagine the simplicity of REST married to the power of Unix pipes with the benefits of a loosely-coupled, logically-layered architecture. If that is hard to imagine, it may because the architectures available to you today are convoluted accretions of mismatched technologies, languages, abstractions and data models.

NetKernel is a disruptive technology that changes the game. It has been quietly gaining mind share in the past several years; people who are exposed to it don't want to go back to the tired and blue conventions of J2EE and .NET. Not only does it make building the kinds of systems you are building today easier, it does it more efficiently, with less code and a far more scalable runway to allow you to take advantage of the emerging multi-core, multi-CPU hardware that is coming our way.

Come see how this open source / commercial product can change the way you think about building software.

NetKernel makes the things you are doing now easier, but also makes new types of systems possible.

A wise man once said, "XML is like lye. It is very useful, but humans shouldn't touch it." If you've had to incorporate XML into your project by hand, you have probably been burned by getting too close. NetKernel turns this wisdom on its head and encourages you to use XML like the liquid data stream you want it to be.

But, XML is only part of the story. Resource-oriented computing is a generalized and revolutionary approach to modern, flexible systems. There is less code to write, but it is more fun to do. Orchestration of existing services and data sources is faster, easier and more encompassing than with more conventional technologies.

This talk will help explain what NetKernel is (app server? pipeline tool? embedded SOA?) and, through a comprehensive set of examples, give you a glimpse at a deeper software reality than you might have thought possible.

Disclaimer: There will be no blue pills given to you to make you forget what you have seen. Come with an open mind.

By Brian Sletten

You're a good Java programmer. You understand the JDK libraries and how to use them. The problem is that many fundamental APIs don't take the bigger performance picture in mind. Garbage collection can end up killing your app if you aren't careful. Concurrency problems and contention can keep your well-intentioned software from leveraging modern hardware architecture that support multi-core and multi-cpu systems.

Who knew that simply using the standard library code the way it was designed was opening you up for performance problems in your apps?

Don't worry, Javolution has your back.

Javolution is a small (300K) API designed to bring many of the benefits of the Real-Time Java Specification (RTJS) to J2SE, J2ME, GCJ and CLDC through deliberate design decisions.

It includes re-implementations of the java.util, java.lang, java.text, java.io and java.xml to demonstrate time-deterministic behavior. It also includes a framework for testing its own performance, supporting parallel computing, communicating with C/C++ applications and a real-time object to XML marshalling framework.

Come see how you can get some of the time-determinism and concurrency benefits in either your client or server side applications. This is a fairly deep talk and is largely a decomposition of an API that changes the runtime characteristics of the VM's runtime performance with only the tools offered by the language and the VM.

You hear a lot of talk about rich clients, but the richness they purport to provide is predicated on having access to rich data as well as a rich user interaction style. Without the right levels of abstraction, it is hard to address and link all of the data we have to care about these days. Additionally, the web sites that do support the notion of linking require you to publish your data into TheirSpace. Forget that. You want to be able to link publicly available information to sensitive information in YourSpace.

Ever since we started doing relational joins, we've looked for ways to tie data together. The problem is, the relational model is a bit tired and doesn't move at the speed of the Net. We need schemes that integrate relational data, web pages, XML files, RSS feeds and various other sources of information.

The good news is that a slew of emerging technologies are starting to make this happen. Come explore integration strategies that allow real mashups to function on both the web and the Enterprise. We can use a variety of languages and tools to link legacy data and modern content sources. We will explore resource-oriented computing as a new way of building systems that manage information spaces, not code.

We will discuss the benefits and deficiencies of XML in this space as well as look at things like JSON, RSS and RDF. We will look at research projects like Simile from MIT, metadata storage systems like Mulgara and scalable orchestration environments like NetKernel. We'll see how to create your own Yahoo Pipes-like functionality without having to publish What happens when you mix the concepts of REST with Unix Pipes and Service-oriented architectures? What happens when you leverage the power of the web as a global data source in the context of your own day-to-day activities?

The first talk will be an overview of the various topics and technologies that enable the rich data. The second talk will focus on how we can create powerful, user and data-driven applications with the rich data we've linked.

A lot of this will be new and on the intermediate to advanced side, but an open mind is all that is really necessary to catch what is going on.

Groovy is an agile dynamic language for the Java platform. The language and its libraries bring many things to the table to ease the process of building applications for the Java platform. This session provides a detailed run through Groovy with lots of code samples to drive home the power of the language.

Dynamic languages provide a lot of power and flexibility compared to statically typed languages. Groovy brings that power and flexibility to the Java platform in a way that is totally compatible with all of your existing Java code, tools and infrastructure. This session covers all of the fundamentals of Groovy and gives developers a whole lot of practical information they need to get started with the language.

By Jeff Scott Brown

Dynamic languages bring a lot of interesting elements to the table for teams interested in doing Test Driven Development (TDD). Groovy lends itself very well to TDD and this session demonstrates many features of the language and its libraries that help teams build more testable systems and build better tests.

The value of Test Driven Development (TDD) has become widely accepted. The practice has extended beyond just XP teams. Good TDD practices yield high quality software and help teams maintain confidence in their software as complexity grows. The dynamic nature of Groovy makes TDD easy and fun. Groovy may be used to unit test not only Groovy code but other code as well. Testing Java code with Groovy is a snap. Learn to use the power of Groovy to test your systems.

By Jeff Scott Brown

Metaprogramming is a key component in building truly dynamic and flexible applications with Groovy. Groovy's metaprogramming capabilities bring great new possibilities to the table that would be very difficult or just plain impossible to write with Java alone. This session will demystify a lot of the magic that seems to be going on inside of a Groovy application.

When Java developers are first introduced to Groovy one of the first things they notice is how much easier things are in Groovy compared to Java. Boilerplate code typically generated by your IDE all melts away to nothing in a Groovy bean. Creating XML is a snap, not a tangled mess. File I/O is a breeze. Those developer productivity gains are an important part of the story. However, in addition to making easy the things you are used to doing the hard way Groovy brings whole new capabilities to the party that Java developers don't even think about because you can't do those things with Java. Many of those capabilities are made possible because of the powerful metaprogramming capabilities of the language. Learning the metaprogramming capabilities of the language takes developers the rest of the way to fully taking advantage of the power of Groovy. The metaprogramming capabilities offered by the language provide everything that an application development team needs to build systems that are far more capable than their all Java counterparts.

Prerequisite: A Thorough Introduction To Groovy

Grails is a full stack MVC framework for building web applications for the Java platform. Grails makes web application development both fun and easy. This session covers all of the fundamentals of building web applications with Grails.

Businesses need rich web applications and developers want to be able to build those applications without the pain that usually comes along with doing so. Grails addresses these needs very well. Grails demolishes many of the pain points that Java developers have almost (not quite) become numb to after years of suffering. This session covers all of the fundamentals:

• Introduction To Grails
• Domain Objects
• Controllers
• GSPs
• Custom TagLibs
• GORM

How do you ensure your applications meet the expectations of your key customers? In this session we will explore using the FIT tool and Behavior Driven Design tools to do exactly this.

Unit Testing helps you, the programmer, verify your application meets and continues to meet your expectations. But how do you ensure that your application meets and continues to meet the real expectations, those of your domain experts and key customers? We will take a look at two distinct approaches for customer acceptance testing. We will take a look at using FIT for testing behavior and at Behavior Driven Design tools and techniques. Both these approaches can helps us create what is called executable documentation and to stay sane in the world of changing requirements and evolutionary design.

By Venkat Subramaniam

Functional Programming Languages (FPLs) have been around for a long time. A lot of features that we get excited about in dynamic languages are common place in FPLs. FPLs are gaining importance due to various changes in our industry. What's exciting is that you can use them on the JVM. In this presentation we will dig into the details of what makes FPLs so interesting and look at ways to use them on the JVM?in your Java projects.

What's Functional Programming? Why is Functional Programming suddenly important? Features of Functional Programming Functional Programming Languages JVM and FPLs Examples of Functional Programming features Examples of mixing Java and FPLs

A good design is critical for success with agile development. That does not mean a big up-front design. The design has to be evolutionary. However, the design you evolve must be extensible and maintainable. After all, you can't be agile if your design sucks.

In this presentation, we will address what evolutionary design is, and will delve into principles and practices that can help realize an effective evolutionary design.

By Venkat Subramaniam

We all have seen our share of bad code. We certainly have come across some good code as well. What are the characteristics of good code? How can we identify those? What practices can promote us to write and maintain more of those good quality code. This presentation will focus on this topic that has a major impact on our ability to be agile and succeed.

Characteristics of quality code Metrics to measure quality Ways to identify and build quality

By David Bock

Most good developers eventually have the opportunity to be managers. Whether they call you the "project manager", "Technical Lead", "Lead Developer", or some other classic middle-management title, you become the 'goto' guy between management and developers. You're the guy who is expected to keep the project in-line, track a schedule, and occasionally answer the question "How's it going?", and perhaps still contribute at a technical level. So how do you do that?

So what do you do next? How do you plan what needs to be developed? How do you know if you are 'on schedule' or heading off-track? Using good ideas from a bunch of successful projects (but no methodology in particular), you will learn the basics of good project planning, execution, and tracking.

While this talk as management methodology agnostic, many of the ideas are tracable directly back to concepts from XP, SCRUM, and even RUP and CMMi. Whether you are following a management methodology or not, the ideas in this talk will be applicable to technical managers.

By David Bock

How many times have you started a new project only to find that several months into it, you have a big ball of code you have to plod through to try to get anything done? How many times have you been the ?new guy? on an established project where it seems like the code grew more like weeds and brambles than a well-tended garden? With a few good structural guidelines and several tools to help analyze the code, we can keep our project from turning into that big ball of mud, and we can salvage a project that is already headed down that path.

This talk will talk about everything from build processes, teamwork, and project structure through versioning, release plans, upgrde strategies, package dependencies, and more. Using real-world scenarios from two projects with 12-15 people working together over a 5-year time span, this presentation will offer advice based on multiple successful deliveries of real software.

By David Bock

Agile software development isn't just about the development team or managers... the customer has an active role too. The customer should be prioritizing the stories in each release, potentially working onsite in constant contact with the development team, and even participating in daily status meetings.

Done well, the customer's presence has a positive influence on the development iteration. Done poorly, the customer detracts from the team's focus. So how do you be the customer of an agile team? How do you teach someone to be that customer?

In this session we will look at an overview of agile methodologies and the role of the customer, customer proxy, and other versions of the "product owner", and their responsibilities in ensuring the success of an agile software development project.

By David Bock

Estimating is regarded as little little more than 'educating guessing', but so much can hang on the quality of those estimates. With good estimates we can set clear expectations for project delivery, but with bad estimates we can run over schedule and over budget, or worse. We often estimate when we know the least about the work that needs to get done - so how can we make the best of what is potentially a bad situation?

In this session we will look at how successful agile teams estimate the scope of work at the beginning of a project, estimate the amount of work that fits into any one iteration, track the work through the iteration, and the 'burn down' through the end of the project. We will look at 'low ceremony' estimation techniques like planning poker, trim down 'high ceremony' techniques like Wideband Delphi, and look at "FET+", an estimation technique originally developed as a foil for a CMMi effort.

With a little effort, a little planning, a little tracking, open communication, and some good metrics, estimation does not have to be a 'crystal ball' activity.

By Scott Davis

There are wild-eyed radicals out there telling you that Java is dead, statically-typed languages are passe, and your skills are hopelessly out-of-date. Those extremists are the same ones who don't bat an eye at throwing out years of experience to learn a new language from scratch, pushing aside a familiar IDE for a new one, and deploying to a whole new set of production servers with little regard to legacy integration.

While this "burn the boats" approach to software development might sound exciting to some folks, it's giving your manager the cold shakes right now. What if I told you that there was a way that you could integrate seamlessly with your legacy Java code, continue to use your trusty IDE and stable production servers, and yet take advantage of many of the exciting new dynamic language features that those fanatics keep prattling on about? You'd probably say, "Groovy!" I would, too...

This talk focuses on integrating Groovy with your legacy Java codebase in a way that wouldn't raise an eyebrow in the most conservative of organizations. We'll look at the dramatic reduction in line of code you can achieve by simply flipping your POJOs (Plain Old Java Objects) to POGOs (Plain Old Groovy Objects). We'll talk about calling Java classes from Groovy, and calling Groovy classes from Java. We'll look at Groovyc, the integrated compiler that manages Groovy/Java dependencies without a hiccup.

Not once will I tell you to throw out the old in favor of the new. In each case, I'll show you how to integrate the new with the old. Don't throw out your Ant build scripts; mix in a bit of Groovy to spice 'em up. Don't toss out your existing unit tests. (You are unit testing, aren't you? AREN'T YOU?) If not, Groovy is the perfect excuse to get started with a new language in way that improves the quality of your Java application without actually putting the new code into production. That is, until you get hooked on doing things the Groovy way...

If the Red Pill of Dynamic Languages scares the pants off of you (or your manager), don't worry about it. The Blue Pill still offers plenty of benefits. There is no other language on the JVM that offers you the level of deep Java compatibility such that you could rename your "dot J-A-V-A" files to "dot G-R-O-O-V-Y" and not skip a beat. Of course, they both end up with a "dot C-L-A-S-S" extension at the end of the day, so there's good chance that no one would ever be the wiser anyway. Groovy: funny name, serious software, and Java through-and-through.

By Scott Davis

This talk focuses on the ways that Groovy can turn a traditional Java developer's world-view upside down. We'll start by talking about how you can thumb your nose at The Man by leaving out many of the main syntactic hallmarks of Java: semicolons, parentheses, return statements, type declarations (aka Duck-typing), and the ever-present try/catch block. Then we'll look at features like operator overloading and method pointers that Groovy welcomes back into the language with open arms.

The bulk of this session focuses on metaprogramming with Groovy. We'll add new methods to classes at runtime -- even if they were originally implemented in Java, and even if they were declared final. (Thanks, ExpandoMetaClass!) We'll call methods that don't exist and avoid the dreaded MethodNotFound Exception. (Thanks, invokeMethod!) We'll narrowly scope our metaprogramming shenanigans using Use blocks and Categories, and then cast our changes to the wind such that every instance of a class gets our added juice.

If you are happy taking the Blue Pill, this talk is not for you. You can continue using Groovy as a slimmed-down dialect of Java -- an 'After' picture to Java's 'Before'. If, however, the Red Pill looks interesting, please join me. Remember, all I'm offering is the truth. Nothing more.

Grails is a Java- and Groovy-based web framework that is built for speed. First-time developers are amazed at how quickly you can get a page-centric MVC web site up and running thanks to the scaffolding and convention over configuration that Grails provides. Advanced web developers are often pleasantly surprised at how easy it is to break out of that coarse-grained navigation model using the native Ajax support baked into the framework.

We'll start with the solid Web 1.0 foundation that Grails provides and mix in JavaScript libraries like Prototype and Scriptaculous. (Both are included with the framework.) Grails tags like remoteLink and formRemote make it easy to asynchronously replace strategic parts of the web page while leaving the whole unchanged.

There is first-class support for JSON (JavaScript Object Notation) in Grails. You'll see how easy it is to return JSON (and XML) instead of the usual HTML using the grails.converters package.

In April 2005, annual growth rates for jobs in JavaServer Faces, Struts, and Ruby on Rails were all at about 0%. Today, Struts' growth rate still hovers around 0%, but JSF and Rails have taken off. At the end of 2007, both JSF and Rails were growing at a rate of between 400-500% annually (according to indeed.com).

JSF has passed the adoption tipping point, and is now the Java-based framework of choice, as is evidenced by its ecosystem. From vendors such as MyEclipse and RedHat to open source projects such as Seam, Facelets, and Ajax4JSF, JSF is where the action is.

Come see why JSF is so popular. In this code- and demo-intensive session, I'll show you the fundamentals of JSF.

This session is taught by a member of the JSF Expert Group for JSF 1.0 and 2.0., and co-author of the best-selling book on JSF: Core JavaServer Faces. David will take you through a whirlwind introduction to JSF including what JSF is, how it was developed, and how you can best take advantage of the technology. Here is a list of topics:

Components, managed beans, value expressions, and static navigation i18n, CSS, and actions The Faces Context and Faces messages The JSF Event Model Using JavaScript with JSF

This introduction to JSF also contains 5 live-code demos, where David will develop a simple, but robust application during the course of the session.

Prerequisite: Some knowledge of Java-based web applications, such as Struts, is a plus, but is not required. If you have a significant experience with JSF, you probably already know most of what's covered in this session.

By David Geary

Facelets is a combination of Tiles and Tapestry, and it's the hottest JSF-related open source project on the planet. It's popularity is well deserved, and in fact, much of what is in Facelets today will make its way into the JSF 2.0 spec due out in 2008. So not only can you come to this session and see some really cool demos that you can put to use in the real world, but you'll also be learning JSF 2.0 before it's even been defined! How's that for a ROI?

This session is 90 minutes of nothing-but-Facelets, so we're going to cover a good bit of ground. You'll see all of the basics, such as templating, error handling and debugging, and some of the more advanced aspects, such as creating your own components and tag libraries.

Prerequisite: Some knowledge of JSF is essential. If you're familiar with a templating framework, such as Velocity or Tiles, that's a plus, but not required.

By David Geary

Ajax4jsf makes it very easy to add Ajax to your JSF applications. Come to this presentation to see how.

The JSF spec has changed little since JSF debuted in 2004. However, the open source community is a frentic cauldron of activity that has produced lots of cool innovations, many of them related to Ajax. In this talk, we'll look at one of the most popular open source Ajax frameworks for JSF, Ajax4jsf.

Ajax4jsf gives you a very capable set of low-level Ajax tags (JSP or Facelets), along with their corresponding APIs, that let you easily incorporate Ajax features, most of the time by just using a custom tag or two. Ajax4jsf is an ideal solution if you want to add Ajax functionality to an existing JSF application.

In early 2008, the JSF Expert Group has begun to focus it's attention on incorporating concepts from best-of-breed JSF Ajax frameworks, such as Ajax4jsf and ICEfaces. What you learn in this session will give you both a preview, and a leg up, on JSF 2.0.

By David Geary

Have you ever stopped to think that you need to learn two frameworks to develop a non-trivial, database-backed, web application? Struts and iBatis; JSF and Hibernate; Tapestry and EJB3.0.

Two frameworks. And then you have to learn to use them together. Why do we have to learn two frameworks just to retrieve "Hello World" from a database and show it in a view. Isn't that crazy?

Now you can use one framework, and use one component model. One. Isn't that nice?

By David Geary

The Google Web Toolkit (GWT) is truly a revolutionary framework that lets you develop Ajaxified web applications without knowing anything about Ajax or JavaScript. But the GWT goes way beyond basic Ajax by letting you implement desktop-like applications that run in the ubiquitous browser.

In this, the first of a two-part session on the GWT, you will learn about the framework and its fundamental capabilities, such as: rapid development with project and application generators; the GWT widget hierarchy; remote procedure calls; the GWT's history mechanism, including its integration with the Back button and bookmarks; and integrating JavaScript frameworks, such as Script.aculo.us, with your GWT applications.

By David Geary

In the second part of this talk, you will learn how to extend the GWT by implementing custom widgets, including a scrolling viewport and a drag and drop framework. After discussing custom widgets, you will see how to integrate database access into your GWT applications, and how to deploy your GWT applications to external servers.

You will also learn how to integrate GWT widgets into legacy applications built with web application frameworks such as Struts, JavaServer Faces, or Tapestry. The GWT is one of the most powerful Ajax frameworks on the planet, and one of the few that let you easily implement desktop-like applications that run in a browser, and because of that, it has gained incredible mindshare in a short period of time. Come to these two sessions on the GWT and see what all the buzz is all about.

Over the last few years, we have taken dozens of projects to 100% coverage, and there are still plenty of things that can go wrong. We will look at examples the various problems, and show how to prevent them from infecting your project.

With an expressive language such as Groovy or Ruby and with modern test practices, 100% C0 test coverage is readily achievable. But 100% coverage is meaningless without other supporting habits and practices. Over the last few years, we have taken dozens of projects to 100% coverage, and there are still plenty of things that can go wrong.

We will look at examples of each of these problems, and show how to prevent them from infecting your project:

* Fragile mocking
* Pair bravado
* The ugly mirror
* Parallel abstraction
* Overspecification
* Underspecification
* Invisible code
* Misplaced exemplar

In this talk, we will explore and compare four of the most interesting JVM languages: Clojure, Groovy, JRuby, and Scala. Each of these languages aims to greatly simplify writing code for the JVM, and all of them succeed in this mission. However, these languages have very different design goals. We will explore these differences, and help you decide when and where these languages might fit into your development toolkit. For more information see http://blog.thinkrelevance.com/2008/9/24/java-next-overview.

As we reach the middle of our second decade of Java experience, the community has learned a lot about software development. Many of our best ideas on how to use a Java Virtual Machine (JVM) are now being baked into more advanced languages for the JVM. These languages tend to provide two significant advantages:

• They reduce the amount of ceremony in your code, allowing you to focus on the essence of the problem you are solving
• They enable some degree of functional programming style. Think of it as a dash of verb-oriented programming to spice up your noun-oriented programming.

In this talk, we will explore and compare three of the most interesting new JVM languages: Clojure, Groovy, JRuby, and Scala. Each of these languages aims to greatly simplify writing code for the JVM, and all of them succeed in this mission. However, these languages have very different design goals. We will explore these differences, and help you decide when and where these languages might fit into your development toolkit.

Dispatch takes many forms. Single dispatch, switch statements, pattern matching, and multiple dispatch all meet similar needs: Selecting runtime behavior in response to varying runtime conditions. Flexible dispatch is a key element of Java.next. All of the Java.next languages support dispatch strategies that are far more flexible than Java's single dispatch. In this talk (Part 3 of the Java.next series), I will explore how the Java.next languages (Clojure, Groovy, JRuby, and Scala) support dispatch.

Git is not the next step in evolution of centralized source control, following in the footsteps of cvs, svn, etc. These tools provide centralized history of deltas, where git provides distributed history of trees of content. In this talk, you will see the advantages of the git approach:

Incredible speed. Local, disconnected operation. Source control workflow customized to your team. Centralized, distributed, or layered, you can build it with git. Cheap and easy branching, tagging, and merging. Editing and refactoring your commits.

You have probably heard about git by now, perhaps something along these lines: "Git is a version control system, and it is more powerful that Subversion in every way. You don't even have to be online to commit!"

This is true, but it undersells git. Git is not the next step in evolution of centralized source control, following in the footsteps of cvs, svn, etc. These tools provide centralized history of deltas, where git provides distributed history of trees of content. In this talk, you will see the advantages of the git approach:

• Incredible speed.
• Local, disconnected operation.
• Source control workflow customized to your team. Centralized, distributed, or layered, you can build it with git.
• Cheap and easy branching, tagging, and merging.
• Editing and refactoring your commits.

The git community prefers power to ease of use, and so git's user interface and documentation can be intimidating. You will learn the straight and narrow path for common, day-to-day git operations. You will also learn git's underlying data model, and get a quick introduction to more advanced concepts like submodules, cherry-picking, and bisection.

As a final bonus, you will see how to use git on an existing subversion project. You can use git as your svn client, and the rest of the team can stay on svn and not even care.

This session introduces the Hibernate Object/Relational Mapping (ORM) framework, showing the basics of persisting Java objects to relational databases. No prior knowledge of Hibernate or ORM is assumed.

Persistence is a key element of most applications, whether web or desktop. Relational databases are the defacto standard for enterprise data storage and object-oriented (OO) programming, for example in Java, is the predominant technique to build applications today. Relational databases and OO, however, are completely different paradigms. Object/Relational Mapping (ORM) seeks to bridge this gap to allow easy persistence of objects to relational databases. Hibernate is a leading ORM framework providing persistence of Java objects to relational databases. This session introduces Hibernate and covers ORM alternatives available today; getting started with Hibernate; mapping objects to database structures; interacting with Hibernate APIs to find and persist objects; transactions; and finally, architectural considerations and suggestions for integrating Hibernate into applications.

Hibernate is a very powerful object/relational mapping framework. With the vast amount of power also comes the responsibility to choose which features of Hibernate to use and how to use them, as well as things to avoid. We'll look at some real world Hibernate tips and tricks in this session.

Hibernate is one of the most popular and successful object/relational frameworks available today. In this session we'll look at some real world tips for using Hibernate effectively. Topics we'll cover include: logging and debugging Hibernate-generated SQL; using annotation mappings, ImprovedNamingStrategy, and MappedSuperclass; understanding lazy-loading and the n+1 problem; basics of performance tuning Hibernate applications; using inheritance in your domain model; managing sessions; effective use of the second-level cache; validation using Hibernate Validator; and when not to use Hibernate in an application.

By Scott Leberknight

Hibernate is one of the pre-eminent object/relational mapping technologies, but the Hibernate Search project adds full-text search capabilities to an already extremely capable tool to allow you to Google your domain objects.

Hibernate Search provides the means to add full-text search to your domain objects by leveraging Apache Lucene under the covers. You control which domain objects are searchable, how they should be indexed, and Hibernate Search takes care of the dirty work for you. It handles the object/index impedance mismatch and the task of managing the search indices. You can also execute full-text searches and retrieve actual domain objects transparently. We'll also discuss various architecture alternatives including using Hibernate Search in both clustered and non-clustered environments.

Prerequisite: A basic understanding of Hibernate.

Drools is an open source pure-Java implementation of a forward chaining rules engine. Drools can be used in a J2SE or J2EE application and allows you to express rules programatically or by building domain specific rule languages. Learn how Business Rules with Drools can make your Java applications more flexible and robust.

Software development is expensive, when business rules are hard-coded in your application's source code, changes and additions to those rules translate to wasted time and money. Good object-oriented, component-based approaches can alleviate the burden of keeping up with changes in the business world but they still require that expert knowledge of the changes be passed from the decision makers to the business analysts and finally to programmers that need to implement these changes. Business Rule Engines and Business Rule Languages are based on the basic premise of separation of concerns by empowering business domain experts to express the rules of business in a way that it is directly usable by applications. Drools is an open source pure-Java implementation of a forward chaining rules engine. Drools can be used in a J2SE or J2EE application and allows you to express rules programatically or by building domain specific rule languages. Learn how Business Rules with Drools can make your Java applications more flexible and robust.

In this session you'll learn some of the more advanced features of Drools; a pure-Java Rule Engine. This session will walk through the construction of an advanced Rules application covering such topics as:

• Fine control and monitoring of a Working Memory session
• Using Decision Tables
• Advanced Rule Language Features
• Building Domain Specific Languages
• Managing your Rules

Many of the problems that we deal with in enterprises around the world are not usually related to the particular infrastructure, framework or programming language chosen but rather to the evolution and maintenance of the business logic that governs those systems. All knowledge in an enterprise is handed down stream until it arrives at the programmer's door. With Rule based systems we can empower those with the business but there is still a fair amount of work to get the ideal architecture for a particular problem in place. In this session you'll learn some of the more advanced features of Drools; a pure-Java Rule Engine. This session will walk through the construction of an advanced Rules application covering such topics as:

• Fine control and monitoring of a Working Memory session
• Using Decision Tables
• Advanced Rule Language Features
• Building Domain Specific Languages
• Managing your Rules
