Session Schedule

By Ryan Breidenbach

In 2006, Spring 2.0 was released and Spring became ubiquitous in the enterprise Java space. So if you haven't taken a peek at Spring yet, what are you waiting for?!? If the answer is "This session," you have come to the right place. This session will familiarize you with the benefits Spring provides and why they have made the framework so successful. In addition, we will focus on the efforts that went into Spring 2.0 to make these benefits much more developer friendly. By the end of this session, you should have a grasp of how Spring 2.0 simplifies the utilization of Spring's core features such as bean wiring, AOP, and the simplification of using enterprise Java. If your head is not spinning too much.

In this session we will cover: - Brief history of Spring - Overview of Spring's core values and features - New Spring 2.0 features - Glimpse of upcoming Spring 2.1 features

By Ryan Breidenbach

Although Spring's rise to ubiquity was driven by its IoC and AOP services, it offers so much more. One of the most powerful of these services is Spring's MVC framework.

If you are familiar with other Java web frameworks such as Struts or WebWork, you will recognize that Spring MVC is a similar request-response web framework driven by a Front Controller, in this case the DispatcherServlet. But Spring also provides considerable functionality out of the box. One of the beauties of the Spring MVC is that, like the rest of Spring, all of its components are quite modular. This allows you to mix and match different implementations of the various MVC components as you see fit for you application.

In addition, Spring MVC provides rich capabilities for data binding. This allows you to transparently bind form parameters to your application objects without having to create any intermediate objects. Spring's validation features allow you to capture both binding and application errors. And with Spring 2.0's much improved JSP tag library, both creating forms and displaying validation errors is quite simple.

In this session we will cover: - A quick overview of Spring for first time Spring users - Configuring Spring's DispatcherServlet - Wiring other application beans to web application beans - Mapping requests to Spring Controllers - Spring's different Controller implementations, and when they should be used - Validation form parameters and binding them to application objects - Creating forms using Spring's custom JSP tags library

By Jeff Brown

Groovy is an agile dynamic language for the Java platform. Groovy has a Java like syntax along with many features inspired by languages like Python, Ruby and Smalltalk. This session covers a lot of ground including many interactive examples to hilite the powerful language features that make Groovy compelling. A lot of momentum is building in the Groovy and Grails communities right now and this session is aimed at Java developers who want to leverage the power of Groovy.

This session is targeted to demonstrate the power of Groovy and help Java developers understand how to leverage that power in their enterprise applications. Topics include: Everything Is An Object GStrings Closures Collections Groovy Builders Groovy Beans Categories Ranges Java Integration

By Jeff Brown

Grails brings the powerful "coding by convention" paradigm to Groovy and Java. Grails is not just another flavor in the pool of web development frameworks for Java. Grails leverages the powerful dynamic features of Groovy while taking advantage of best of breed technologies like Hibernate, Spring, Sitemesh and Quartz to make web application development both fun and easy.

This session will demonstrate how easy it is to get a simple application up and running with almost no effort and then evolve that application by adding features to really show off the power of the Grails framework. Topics include: Grails Quick Start The Grails Command Line Tools GORM and Hibernate Groovy Server Pages (GSP) Spring Integration Unit Testing Functional Testing

By Jeff Brown

Grails represents technology that offers great flexibility and power without the complexity introduced by other Java web application frameworks. Custom tag libraries are a snap. GSP Templates provide a simple mechanism for reusing UI elements. Sitemesh is integrated to help provide a consistent presentation across the entire application. Grails provides simple mechanisms for leveraging the power of Ajax.

This session will cover all of these topics to demonstrate how powerful the Grails framework is and show how little effort it takes to build not just a simple toy application but also to build real enterprise web apps.

By Jeff Brown

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.

This session will cover using Groovy to test Groovy and Java code, web applications and desktop applications. The session will include a lot of live code examples demonstrating the power of Groovy in testing.

This talk avoids SOA hype and gets to the meat of the matter: how do you implement a Service-Oriented Architecture, what are the technological pitfalls, how do you test it, and what traps should you avoid. No marketecture: just implementation details.

No subject has been subject to more recent hype than Service-Oriented Architecture (I think it was because of a really good article in an in-flight magazine). For whatever the reason, the CxO has decided that we need one. It's up to you to implement it. This session is all about the technical considerations required to implement a service oriented architecture. It discusses technology choices, what is in (and out) of SOA's scope, how to implement transformations, routing, and other key services, how to version endpoints, and finally testing and debugging SOA. This session is marketecture free: it covers the details you need to implement this style of architecture. Session Topics:What SOA me

This session discusses building Domain Specific Languages and DSL-style code in Java, Groovy, and Ruby. It discusses the different types of DSLs, details on how to implement them in Java, Groovy, and Ruby, and example problem domains where DSLs make sense.

You've heard all the hype for the past couple of years: Domain Specific Languages (DSLs) are going to take over the world. This session demystifies this topic in 2 ways: by providing concrete definitions for styles and applicability of DSLs and showing how to implement these different styles. I build up definitions for the different types of DSLs in static (Java) and dynamic (Groovy and Ruby) languages. Then, I discuss building DSLs as internal (i.e., built on top of an underlying language) and external (built using a preprocessor or grammar), with examples of each. Throughout this session, I discuss the applicability of this style of development and show targeted examples. I discuss fluent

You can read books about Agile projects, but you must consult real-world experience to really understand the dynamics of agile project management. This session discusses agile management topics including estimation, project tracking, and useful metrics (and how to obtain them). And just a little about Mingle, the agile project tracking tool from ThoughtWorks.

OK, sure, you can read the XP Explained book. Now what? Agile project management in the real world requires understanding of not just the practices but why they work. This talk delves into several topics relevant to agile project management, including estimation, project tracking, accurate project metrics (and the practices that make them possible). This talk is designed to describe some of the nuances required to handle real agile projects, along with a demonstration of some of the artifacts ThoughtWorks uses to track projects (the most elaborate spreadsheet you've ever seen!). And, towards the end, I show how our experience has culminated into Mingle, the agile project tracking tool from T

About bridges, languages, engineering, polyglot programming, and the near future.

Other engineers sneer at us when we call ourselves "Software Engineers", and they have a point. This keynote discusses real comparisons between traditional engineering and the software kind. It also delves into what it will take to make our profession a real engineering discipline and the near future of languages and environments. Come see your future.

By Neal Ford

Regular expressions should be an integral part of every developer?s toolbox, but most don?t realize what an important topic it is. Regular expressions have existed for decades, but many developers don't understand how to take full advantage of this powerful mechanism, either through command line tools and editors or in their development.

This session shows how to fully exploit regular expressions. It begins with the basic premise of how regular expressions work, then shows how to take advantage of the RegEx library built into the Java platform. This session shows how to use wildcards, escape characters, meta-tags, character class operators, look-aheads/look-behinds, and how to use the greedy operators effectively. It covers regular expressions from the beginning through to advanced usage, both in Java and in tools that support regular expressions. This session is packed with real examples of regular expressions (including a game show with no fabulous prizes). Key Session Points: Regular expressions defined Examples Using t

No one writes perfect code: even the best developers fall into bad habits and traps. These topics from The Productive Programmer illustrate blind spots and helps you write better code.

It is too easy to get into a coding slump and not realize it. This talk revitalizes your relationship to code, forcing you to rethink some of the thing that you take for granted and showing new approaches to solving hard problems. It covers topics that range from improve the overall structure of your code to the way you write JavaBeans, with lots of examples. Everything in this talk may not be new to you, but I guarantee that you'll see some things that will make you reevaluate the way you think about your code.

This session discusses how to use the Productive Programmer principles of acceleration, focus, and indirection to become a more productive programmer. This session describes these principles, but the primary focus of this session is demonstration of these principles with real-world examples.

In The Productive Programmer, David Bock and I identify 5 principles of productivity: this talk goes into great detail on 3 of those principles. The 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 keyboard shortcuts (including ways to make better use of them) in both IntelliJ and Eclipse. Focus describes how you can modify both the operating system and your code base to eliminate noise. Indirection shows how a simple concept can have profound effects, including how to share a common set of plugins across an entire Eclipse

The 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. Canonicality (the DRY principle from The Pragmatic Programmer) discourages repeating artifacts in projects. This talk shows effective ways to avoid this repetition. For example, I show how to reuse documentation via a Subversion hook that posts comments to a Wiki with an RSS feed. Automation refers to making the computer do more work for you. This t

This session describes JRuby, the 100% pure-Java implementation of the Ruby programming language. It covers the basics of programming with JRuby and examples of how to integrate it into existing Java projects.

Like hamburger & fries and turkey & dressing, JRuby allows you to harness the awesome power of Ruby in your Java projects. This session describes the origins, capabilities, and limitations of JRuby, the 100% pure-Java implementation of the Ruby programming language. This session also demonstrates some areas where it makes sense to mixin Ruby and Java code: Rails on Java, testing, and dynamic programming. JRuby is a powerful implementation of Polyglot Programming, and this session shows you how to leverage this cutting-edge concept.

This session explains all the hype surrounding Ruby on Rails, in a context familiar to Java developers. It covers convention over configuration, ActiveRecord, controllers, views, Ajax, scaffolding, testing, and deployment...on the JVM, using JRuby.

Find out why everyone won't shut up already about Ruby on Rails! This web framework for Ruby has appeared from nowhere to become the critics darling: there must be good reasons why. This session shows those reasons, in a context familiar to Java developers. It discusses how configuration works in Rails, persistence through ActiveRecord, scaffolding, controllers, views, and Ajax. It also covers the important topic of testing, and how Rails makes it easy and automatic. Finally, this session discusses deployment on the JVM, using JRuby, and reflects back on the important lessons that Rails teaches Java developers. This session also presents information about the boundary between Rails, Ruby, a

The practice of continuous integration facilitates early visibility into the development process by regularly conducting software builds, thus integrating disparate software pieces earlier than later, which often times minimizes the interval between when a defect is coded and when it is discovered. Given the automated nature of continuous integration spawned builds, software teams can now start to look at their build process as something more useful than a simple compile and test process.

Given the automated nature of continuous integration spawned builds, software teams can now start to look at their build process as something more useful than a simple compile and test process. Builds can be augmented with a series of Software Inspectors, which report on various aspects of software quality, such as code complexity, code duplication and code dependences to name a few.

Behavior-driven development, or BDD, has attracted a lot of attention a la RSpec in the Ruby community, but BDD's roots stem from JBehave, a Java based framework. In this session, we'll look at what BDD is and how it shifts the traditional testing vocabulary from being test-based to behavior-based.

Are your Ant builds giant XML files that scream for attention? Why not enhance your build process to act like a quality gate, much like a test suite would?

Are your Ant builds giant XML files that scream for attention? Why not enhance your build process to act like a quality gate, much like a test suite would? In this session, we'll look at managing 3rd party dependencies with Ivy and then add the power of Groovy to script in quality checks, such as monitoring complexity; plus, we'll look at how to create a customizable dashboard via Groovy.

There's no question that Ant is the de facto standard for building Java applications; however, even its creator has acknowledged an inherent limitation with Ant's expressiveness due to its reliance on XML.

There's no question that Ant is the de facto standard for building Java applications; however, even its creator has acknowledged an inherent limitation with Ant's expressiveness due to its reliance on XML. Recently, the popularity of Ruby and the Rails framework has brought to focus Ruby's de facto build platform: Rake. Rake's expressiveness comes from its reliance on Ruby itself to define a DSL for software assembly. While Rake's ultimate focus is Ruby, there are a number of interesting projects that utilize expressive DSLs for building Java including Gant, which uses Groovy as a DSL format, and Raven, which attempts to enable Rake?s functionality for building Java.

Design Patterns are proven and powerful techniques that can help improve the resiliency, maintainability, and extensibility of your applications. However, overusing or misapplying patterns is a common mistake often times resulting in applications that are over-architected, and resemble a tangled web of classes. How can patterns be applied to achieve the goal of better software?

This session offers a gentle introduction to design patterns by examining a small, yet very usable framework designed using 7 common GOF patterns. We?ll examine the framework, and explore how each pattern is used as well as how each pattern emerged based on real, instead of perceived need. Less flexible alternatives to the chosen patterns will also be discussed. To conclude, we?ll examine how the patterns are applied in conjunction with each other, forming more complex compound patterns. Each pattern will be presented with accompanying source code, and all examples are gleaned from real world scenarios.

By Kirk Knoernschild

Why is software so difficult to change? When you establish your initial vision for the software’s design and architecture, you imagine a system that is easy to modify, extend, and maintain. Unfortunately, as time passes, changes trickle in that exercise your design in unexpected ways. Unlike what you had anticipated, each change begins to resemble nothing more than another hack, until finally the system becomes a tangled web of code that few developers care to venture through. Eventually, modifications to the software intended to improve the system have the opposite affect of breaking other parts of the system. The software is beginning to rot.

The most common cause of rotting software is tightly coupled code with a heavy dependency graph. This session explores the most common symptoms of rotting design, examine their root cause, and present techniques and patterns that have been used on a number of real world projects to help manage dependencies across classes, packages, and the binary units of deployment.

By Kirk Knoernschild

Traditionally, we attempt to make the right architectural decisions early due to the significant anticipated cost affiliated with making incorrect decisions. But this contradicts agile practices which have taught us to embrace change. So how do agile and architecture come together? Conceptually, the goal of agile architecture must be to eliminate the architectural significance of change by crafting software that can easily adapt to change. In practice, developing agile architecture is much more difficult.

Software architecture is organic. The architectural goals you set to achieve early in the development effort differ from those you'll need to satisfy later. Change occurring throughout the software development lifecycle impacts architecture. The ability to accommodate shifts in architecture is directly related to the dependencies between software modules. In this session, we examine patterns and principles that lead to agile architecture. Extensive discussion is devoted to modularizing units of deployment, and how code can be created and organized to create more flexible, reusable, maintainable, extensible, and testable software components. Topics of discussion range from coupling between cl

Java's threading capabilities took a serious turn for the better with the release of Java5, thanks to the incorporation of the java.util.concurrent packages, a set of pre-built components for thread pooling and execution, synchronization, and more.

In this presentation, we'll explore the Thread API, the Java threading model beneath it, and the enhancements made in Java5 to make it easier for Java code to walk and chew gum at the same time.

By Ted Neward

Java's threading capabilities have been a part of the Java platform since its inception, yet for many Java developers, using Threads still remain a dark and mysterious art, and synchronization beyond the use of the "synchronized" keyword is almost unknown.

In this talk, we'll explore the Java "monitor" concept, and how a monitor isn't quite the same thing as a lock from other concurrency systems. We'll see how monitors can be used to perform signalling across threads, and then how the new java.util.concurrent API (introduced in Java 5) can be used to simplify the same sorts of tasks that used to require deep knowledge of the synchronized keyword. Finally, we'll answer that age-old question, "Why did the multithreaded chicken cross the road?"

Wondering why your enterprise Java app just... sucks? Trying to figure out why you can't get more than 10 concurrent users online at the same time? Looking for ways to try and spot the slowdowns and ways to fix them?

In this talk, we'll look at the various things that can occur in an enterprise Java app (from the smallest web site to the largest multi-resource environment) to make your Java apps perform and scale less well than they should, and how you can work to correct them. We'll examine a variety of broad concepts to apply in architecture and design, and examine what factors make an enterprise application slow, then use a variety of tools to figure out how to remedy them.

By Ted Neward

If you've ever gotten a ClassCastException and just knew the runtime was wrong about it, or found yourself copying .jar files all over your production server just to get your code to run, then you probably find the Java ClassLoader mechanism to be deep, dark, mysterious, and incomprehensible. Take a deep breath, and relax--ClassLoaders aren't as bad as they seem at first, once you understand a few basic rules regarding their operation, and have a bit more tools in your belt to diagnose ClassLoader problems. And once you've got that, and hear about ClassLoaders' ability to run multiple versions of the same code at the same time, and to provide isolation barriers inside your application, or even compile code on the fly from source form, you might just find that you like ClassLoaders after all... maybe.

Mustang, the Java6 release, is out, and even if you're not looking to adopt the new platform right away, it's important to know what's there so you can start to plan for it. In this presentation, we'll go over the major new features of the Java6 platform, including the new integrated XML services capabilities (JAX-WS and JAXB), dynamic/scripting language support (javax.script), new JVM "attach" capabilities, new annotations supported by the javac compiler, and more.

For an audience comfortable with some prior Java experience, preferably familiar with Java5.

If you've been keeping your ear to the ground, you may have heard some talk recently about "rules", "business rules" and "rules engines", but not necessarily any clear discussion on what they are, how to use or design them, or why they might be useful or important.

This presentation puts some concrete definition around what a "rule" is, how a "rule engine" like JESS (Java Expert System Shell) can enable your users to be more agile than they ever thought possible, where JSR-94 fits into both the J2EE and "lightweight" development environments, and how you can (finallY!) get out of the "infinite if-else game".

Permissions, policy, SecurityExceptions, oh my! The Java platform is a rich and powerful platform, complete with a rich and powerful security mechanism, but sometimes understanding it and how it works can be daunting and intimidating, and leave developers with the basic impression that it's mysterious and dark and incomprehensible. Nothing could be further from the truth, and in this presentation, we'll take a pragmatic, code-first look at the Java security platform, including Permissions, the SecurityManager and its successor, AccessController, the Policy class and policy file syntax, JAAS, and more.

For an intermediate-level audience.

By Ted Neward

Want to get the soup-to-nuts story on Java annotations? In this presentation, we'll first talk about what annotations provide to the Java language. After setting ourselves a conceptual basis to operate from, we'll look at the language definition for Java annotations, from how to use them to how to define them. Finally, we'll take a look at the other side of annotations, consuming them at source-level (using "apt", the annotation processing tool), class-level (using a bytecode toolkit such as BCEL), and at runtime (using enhancements to the Reflection API made in Java5).

For an intermediate Java audience.

By Ted Neward

Bugs? We all know your code has no bugs, but someday, you're going to find yourself tracking down a bug in somebody else's code, and that's when it's going to be helpful to have some basic ideas about bug-tracking in your toolbox. Learn to make use of the wealth of tools that the Java Standard Platform makes available to you--tools that your IDE may not know exist, tools that you can make use of even within a production environment.

Learn to use jdb, jconsole, jps, jstat, and other tools to identify and squash software defects that just won't reveal themselves during development. Then, just in case those tools aren't enough for you, we'll look at how to write your own, special-purpose tools using the same technology backplane.

So you've convinced the boss that your new web application just has to have Ajax...but now what? With dozens of libraries making even the most blinkish of interactions trivial, how do you decided where to sprinkle the magic Ajax dust? This talk will give a plain old boring "web 1.0" an Ajax facelift with a focus on improving the user experience providing you with a game plan for introducing Ajax to your world.

Ajax might not be the most complex thing the average web developer has ever encountered but that doesn't mean building Ajax applications is without some quirks. While you can certainly use the raw technologies beneath Ajax or even roll your own framework, there are a number of well-designed open source libraries that you can take advantage of. After providing a quick survey of the field, this talk will feature live coding examples comparing and contrasting some of the more mature Ajax toolkits including Dojo, Prototype, script.aculo.us and YUI. We'll show you what these various libraries do and do not provide and give you some ideas about which ones make the most sense for your needs.

When starting a new project, most developers make sure that testing is a priority. However, only the lucky few live in the idyllic world of greenfield development; the vast majority of us must contend with code written when "test" was a four letter word and testing was the sole responsibility of that "other" organization. We'll examine some techniques for introducing testing - not just to your code but to the rest of your development organization.

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

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 encompas

Ever since we started doing relational joins, we've looked for ways to tie data together. The web has given us no end of new data sources to integrate but it seems like the best we can come up with is locating Starbucks on Google Maps. The problem with browser-based mashups is that they don't survive the session, we have no way of referring to the results in future queries and ultimately we don't maintain ownership or control of the process.

We want control of our data and our mashup results. We want ever more ways to view, explore and requery them in multi-faceted ways. Do you know what your data integration strategy is for the next few years? Are you sure? You owe it to yourself to come find out.

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. What happens when you mix

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.

Object-oriented code metrics are a little like Artificial Intelligence: those who did it twenty years ago roll their eyes at the thought and prophesy the same ultimate failure at applicability now. Those who grew up with Java are approaching the topic with new eyes and are finding useful ways of incorporating metrics into their projects. Come hear about tools and ways to measure properties of software, how they might be beneficial and where you are likely to go astray with this approach.

Attendees will learn about Approaches to measuring software The attempt to predict failure via software metrics (and the failure to do so) Analyzing OO designs based on the "Martin Metrics" Tools that allow developers to use metrics for themselves Rating: Intermediate Category: Architecture/Languages, Design, Core Java, .NET Prerequisites: Basic Java or C# skills

Ok, I can't promise you profit, but hopefully you'll have fun. Maven 2 introduces a number of new features (including that performance feature) that make it a swell project management tool for development.

Come hear about how we can abuse Maven to manage distributed deployment scenarios before the Modules JSR is done.

This talk will introduce Maven 2 and what it has to offer as a team-oriented development and project management tool. Then we will take a strange turn and discuss how the MavenEmbedder API can be used as a lightweight, low-admin deployment mechanism for self-updating, distributed Java installations. This is a very example-driven talk. We'll look at lots of code but you'll be able to walk away with a fresh take on how to roll out a new versions of entire applications, bug fixes, security patches or new features with very little effort.

Software engineers are usually familiar with the notion of scheduled tasks and cron jobs at the OS level. Quartz is a relatively new open source Java API for scheduling jobs in your applications or Enterprise.

The Quartz API grew out of the Open Symphony project into a powerful way to schedule jobs in the Enterprise. It can easily be embedded in your client side applications or clustered on the server side for participation in JTA transactions. This talk will be an example-driven walk through beginning with the basic features and ending with large-scale clustered and standalone job engine servers backed by databases. This talk should be accessible to anyone interested in a job scheduling engine.

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 the new vision of machine-processable documents and metadata to improve search, knowledge discovery and data integration and management. While there are many naysayers chiding such grand visions, there are also pragmatic and useful technologies emerging that can be applied today.

Attendees will learn: The history and motivations behind the Semantic Web The technology stack that will make it happen (including RDF and OWL) An overview of tools and technologies that are beginning to satisfy the vision This talk stands on its own, but feeds into the "Experiencing the Semantic Web" talk which is more hands on. Rating: Intermediate Prerequisites: This is all so new, most engineers will find something to excite them.
