Software development happans in your head; not in an editor, IDE, or design
tool. We're well educated on how to work with software and hardware, but what
about wetware -- our own brains?

Join Andy Hunt for a look at how the brain really works (hint: it's a
dual-processor, shared bus design) and how to use the best tool for the job by
learning to think differently about thinking.

How you learn new technology and acquire new skills is key to your personal
success. But how do you learn how to learn? What tricks tips can you use to learn more faster, and retain more of what you learn?


Join Andy Hunt for a presentation that includes a brief recap of The Dreyfus
Model (from his popular talk "Herding Raceshorses and Racing Sheep") and see
how to Accelerate Learning and Manage the Torrent of new information using
methods ranging from the tried-and-true to the truly exotic.

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.

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.

Agile programming is a collection of core principles and techniques that allow software developers to create lighter, more responsive applications, and to have fun doing it. Many established organizations are either openly or sub-conciously hostile to many of the principles of Agile development.

We'll explore the intersection of these new practices and old-world sensibilities, relying on real-world case studies to illustrate some of the compromises that are necessary to bridge the gap. In addition to technical and process aspects, we'll also spend some time talking about the business aspects, such as how Agile development affects contracts.

By Bruce Tate
In this session, we'll review the new features of Spring 2.0. If you've been using Spring 1.x, you'll want to hear about the improvements.

This material comes directly from Interface21. The SpringFramework version 2.0 brings tremendous maturity to one of the most successful Java projects of our time. In this session, you'll see

- Radical improvements in the simplicity of context definitions
- Much better AspectJ integration
- Unified user interface strategies, and the continued emergence of WebFlow.

By Bruce Tate
The state of the art is progressing rapidly, and dynamic languages are driving the revolution. Find out about these topics that will be central to programming. We'll discuss continuation servers, metaprogramming frameworks and functional langauges.

Seaside provides a much richer web development experience than you can find in Java today. Learn how continuations can radically improve your web development experience, and learn what Java frameworks are doing about it.

The programming world is abuzz over the Rails framework, but how many of the ideas are exclusive to Rails? We'll look at Active Record, and discover the fundamental innovations that let it happen. What improvements might be made by Java persistence frameworks, and where does Active Record come up short?

Concurrent programming will come to a head with the introduction of multiprocessor systems. We'll discover just how broken conventional langauges are. Also, see how functional languages solve this problem.

By Bruce Tate
Most conferences will try to tell you that the secret to good software development lies with a process, or a technology, or an architecture. Here's a dirty little secret. You can build working software with an outdated two tier archtiecture, a waterfall process and COBOL. How? By building a great team. These techniques were used to build one of the most unique and complex up and coming Ruby on Rails sites.

By far, the biggest factor in the success or failure of a software project is the quality of your team. Build a great team first, and great software will follow. In this session, we'll explore ways to build effective teams for modern software development. Whether you're a project manager or a technical lead, you need to know how to build the most effective team possible. In this session, we'll look at all aspects of team building, including

- What team sizes are optimal for software projects?
- What tools can help your team communicate?
- How does development process come into play?
- How do you build better software faster?

Ruby recently enjoyed its tenth birthday. Instead of cake and candles, the community celebrated by releasing a wave of new libraries and frameworks that make Ruby programming even easier. This talk features some of the best of these, as we explore Ruby.


We'll spend about half the session getting to know Ruby: the syntax, type system, blocks, iterators, and so on. Then we'll dive in and develop some real-world code using web services, RSS, and databases. If you want to come to the Rails talk, and you're not that familiar with Ruby, this talk is a good starting point.

By Dave Thomas
The Ruby on Rails framework has exploded onto the scene over the last few months. Propelled by some genuine benefits, and fueled by a whole lot of controversy, Rails seems here to stay. So, is it a Java killer? (No.) Is it a great way to develop certain classes of web application? (Yes.) Does it really deliver the 10-fold increase in developer productivity that some have claimed? (It depends...)



If you can't help thinking that there must be an easier way of developing web projects, come and join us as we construct an MVC-based Ruby on Rails application using the very latest libraries and tools. You'll get a taste of Ruby, and also a feel for some of the power and productivity gains offered by this remarkable framework. You'll need a grounding in Ruby to get the most from this talk; if you're not already a Ruby developer you might want to attend the Facets of Ruby talk before coming to this one.

By Dave Thomas
The Ruby on Rails framework has unit and functional testing baked right in. In this talk we'll see how easy it is to get started with testing in Rails, and we'll explore jut how deep the testing support goes.

We'll look at the basics: unit testing models and functional testing views and controllers. But we'll dig deeper, looking at the supplied mock objects and seeing how easy it is to add our own. We'll also investigate test fixtures, using them to generate both static and dnamic test data. Finally, we'll have a quick look at performance testing.

By Dave Thomas
Ajax is becoming a requirement for new applications: it creates richer
user experiences and more dynamic applications. However, doing Ajax by
hand is difficult and error prone. The good news is that if you use
Rails, you don't have to do Ajax the hard way.

Rails has built in helpers that support Ajax development,
and comes packaged with the powerful prototype.js and script.aculo.us
libraries.

Come see how Ajax can be made to work with your Rails applications as
we built a very dynamic ToDo list, and see how Ajax can be made robust
with a simple calculator.

By David Geary
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
In 2005, JSF hit its stride, as evidenced from overwhelming support from both vendors and the open-source community. JSF 1.0 had plenty of holes, but open-source projects have arisen to address those needs. This session takes a look at three of those projects: Tomahawk (MyFaces component library) FaceletsSeam

MyFaces is an open-source implementation of the JSF spec. In addition, MyFaces developers got a little carried away and also developed a useful set of custom components that you can use in your own applications, regardless of whether you use MyFaces as your JSF implementation. Those components are now packaged separately from MyFaces under the name Tomahawk.

Facelets is an open-source project from java.net that lets you implement views with Tapestry-like HTML pages. That technique is a powerful feature that lets graphic designers and software developers work separately in parallel.

Seam is a framework from JBoss that provides a component model that unifies the EJB and JSF component models. Seam makes great use of annotations to meld EJBs and JSF components in a seamless fashion (thus the name).

Lots is happening in the JSF space. Come to this talk and learn about these three exciting open-source projects.

By David Geary
JavaServer Faces is a well designed user interface framework, but it lacks a number of features you might otherwise expect out of the box; for example, JSF does not explicitly provide support for client-side validation.

So, from the folks that brought you Struts, comes Shale, a collection of useful enhancements to JSF. A top-level Apache Software Foundation project, Shale adds some really cool features to vanilla JSF, including:

Web flow: script dialog flow
Remote Method Calls: easily call JavaBean methods from JavaScript
Tapestry-like views: code views in pure HTML
Use Apache Commons Validator validators on the client or server, or both
JSF testing framework: mocks for easy JSF testing

There's a lot of cool stuff in Shale that makes JSF a much more compelling proposition. Come see what it's all about.

This is a code-intensive, fast-paced look at Apache Shale. Forty-plus slides and five demos makes for an action packed session that illustrates the cool features that Shale provides.

By David Geary
User interfaces are usually the most turbulent aspect of an application during development. Constant tinkering with the UI means constant changes to your code, so as a UI developer, you want to minimize the scope and effects of those code changes.

Open-source Java provides two powerful software packages that help you manage UI complexity: Tiles and Sitemesh. Tiles composes webpages from discrete regions of your user interface known as tiles. A tile contains a JSP page for layout and one or more JSP pages for content. Sitemesh decorates webpages with decorators that can be associated with URL patterns. Once you set up your decorators, you can decorate pages that match a decorator's URL pattern.

Come see how to use Tiles and Sitemesh with a guided tour from the inventor of Tiles, who has recently become a Sitemesh believer.

By David Geary
JavaServer Faces is a perfect platform for implementing Web 2.0 interfaces with Ajax. This session explores how you can use these two potent technologies--JSF and Ajax--together to create applications that look and behave like desktop applications but run in the browser.

JavaServer Faces, with a mature component model and flexible lifecyle, is a perfect platform for implementing Web 2.0 user interfaces with Ajax. This session explores using JSF and Ajax to create applications that act like desktop applications but run in a browser.

We'll start with a quick look at implementing basic Ajax in a JSF application. Then, once your bloodthirst has been slaked, we'll dive deeper into Ajaxian Faces dynamics with a form completion demo that requires its implementor to understand two simple, but vital facts about JSF.

If you're savvy, you probably use client-side validation to augment your server side validation logic, which parenthetically, is no no-brainer in either of the leading web application frameworks, JSF or Rails. But anyway, client-side validation is old school. All the cool developers nowadays use Ajax to implement realtime validation, where you sneak a trip to the server as an unwary user types into your input fields. But to accomplish that, we'll have to dive even deeper into JSF, with concerns such as accessing view state and accounting for client-side state saving.

All of this Ajax development is great fun, but most of it is best relegated to components and frameworks, which are the topics that will wrap up our session. We'll see how to keep your JavaScript separate from your JSF components and how to pass JSP tag attributes all the way through to JavaScript. Finally, we'll take a look at Ajax4jsf, a JSF component library with a tag library that blends Ajax into JSF in a natural, intuitive way without having to write JavaScript.

As web developers, we've been handcuffed long enough by the shackles of Web 1.0 development. Come to this session and see the brave new world of Web 2.0 development with one of the hottest web application frameworks.

The participants of this session will become agile customers and product owners, using personas to create stories for a sample product development.

The questions around user stories are many, and the list grows larger as their popularity of increases. Many organizations are on their path to adopting stories as requirements vehicles, possibly struggling with story writing as well as finding a way to fit them into their organization. Along with writing stories, this session will cover connecting with product owners and a short review of several tools for tracking and managing user stories.

By David Hussman
This session will focus on tools and techniques for tracking an agile project plan from creation to project completion.

As agile grows, so too do the questions for how to track and communicate progress within the project community as well as to upper management and others interested in progress. We will create a simple plan in a planning tool, and run a mock project, showing how to estimate and use agile planning to communicating progress, addressing missed estimates, scope modifications, and more.

By David Hussman
Adopting agile is different for each company, but most companies will go through some amount of change during the adoption of agile.

This session will discuss some of the most common difficulties for adopting agile and provide various plans of attack. The session will start with a listing of issues for the session participants, and some portion of the session will be dedicated to an open forum where the presenter will address the issues collected.

By David Hussman
As with many methodologies, moving agile into an organizations poses larger challenges. Before jumping in, it helps to ask a few questions before "racing toward agility". This session will provide 3 tactical steps that can help your adoption of agile.

There are many factors outside the developer world that can crash all the benefits of agile without regard to its success. This session will provide ways to select agile practices, create a transition plan for adopting agile, and bring people together before trying to adopt new techiniques that are part of agile development. Various tools and techniques will be discussed, and at least part of the session will include Q/A for the presenter to field specific questions about your organization.

With the sudden importance of Ajax, it's time to take JavaScript seriously. That means learning it the right way: looking at the fundamentals of the language and surveying its strengths and weaknesses, instead of just copying other people's poorly written examples.

JavaScript got a bum rap. It's almost universally derided among serious programmers for being a toy language, or for its strange characteristics, or bugs, or slowness, or because it's only good for adding useless window dressing to web pages.

But JavaScript is actually a very nice little language which is popping up everywhere these days (not just in Ajax apps). Sure, JavaScript is quirky, but its problems are mostly due to history, association, and misunderstanding. Especially misunderstanding. Let's face it: most developers learned JavaScript by looking at examples in web pages they found online, and few of those examples are paragons of JavaScript style. Other developers learned JavaScript from books, but the typical JavaScript book ignores the fundamentals of the language, instead focusing on examples and the fastest ways to do fancy web page tricks.

In this talk, we'll go back to the basics that most JavaScript resources omit. We'll talk about JavaScript as a language, learning its fundamental concepts and the simple rules that underlie the sometimes bewildering behavior.

By Glenn Vanderburg
Building on part 1, this talk dives deep into JavaScript's object model. We'll see how it differs from more mainstream object-oriented languages, and why. We'll explore how to hide some of those differences, as well as the reasons you might not want to. Additionally, we'll cover useful tools for JavaScript testing, debugging, and profiling.

Ajax is not the focus of this talk, but a strong foundation in JavaScript is essential for working with Ajax.

By Glenn Vanderburg
Performance myths about the Java platform abound, from the general "Java is slow", to the more specific "reflection is slow", "allocation is slow", "synchronization is slow", "garbage collection is slow", etc. Many of these myths have their root in fact (in JDK 1.0, everything was slow); today, not only are many of these statements not true, but Java performance has surpassed that of C in many areas, such as memory management.

In this class, we'll look at some common Java performance myths, identify where they came from, and explore the platform changes that have rendered them no longer true. Many common performance hacks don't actually help, and some can seriously hurt performance. The result is that clean code that follows common usage patterns generally shows far better behavior on modern JVMs than code laden with tweaks designed to "help" the JIT or garbage collector. More often than not, this well-intentioned assistance has the unfortunate effect of undermining many common JIT optimizations, resulting in slower -- not faster -- code.

a.. Do you spend more time fighting your tools than writing code?
b.. Do you avoid merging your code with your teammates because of “Integration Hell”?
c.. Do the same bugs keep sneaking back into your product?
d.. Do your builds depend on the roll of the dice?

A good set of infrastructure tools can go a long way toward smoothing out these and other problems. Come see how to make your toolset work seamlessly in the background so you can Just Work. We'll cover source code management (SCM), build scripts, automated test harnesses, automatic builds, feature tracking and issue tracking.



As part of the session, we'll set up Subversion, create a project, and then add code for the SCM section ... just to obliterate the "it takes too much time to set up and use" argument. For build scripts, we'll add an Ant script. Let's throw in a few JUnits to demonstrate test automation, and then I'll put it all together in CruiseControl. The live demo will include breaking the build, then breaking the JUnit test, and then finally fixing it and seeing it all work.

For this first session, we'll look at Subversion, Ant, and start the Cruise Control discussion.

By Jared Richardson
This talk is a continuation of Part One of the Tools talk. During Part Two we'll cover Continuous Integration, automated testing, bug tracking, and feature tracking.

We'll set up CruiseControl and walk through it's functionality, then look at JUnit and how it fits into CruiseControl and the Continuous Intregration idea. Finally, we'll talk about tracking features and bugs.

If you don't make Part One you can still attend and benefit.

O/RM (Object/Relational Mapping) seeks to eliminate repetitive or tedious work enabling the CRUD (create, read, update, delete) that underlies most applications. Hibernate is a popular, open-source O/RM tool that uses reflection (instead of code generation, like EJB, or bytecode injection, like JDO) to manage your persistence layer. This session will introduce you to Hibernate. After an overview of common usage scenarios, including web and enterprise applications, we'll examine the basics of getting Hibernate running. We'll cover the mapping file format and syntax, including common relational mapping structures. Then, we'll examine the Hibernate API for interacting with the framework. Finally, we'll cover the common architectural decisions you'll have to make as you include this (or any other) O/RM framework.

Hibernate is easy to get started with, but can sometimes be hard to make efficient or secure. In fact, the default settings for Hibernate createapplications that will run slowly, cause unwanted round trips to the database, and may be more restrictive and/or permissive from a security standpointthan you would otherwise want.

This session will show advanced techniques for tuning performance, including:
• advanced collection mapping strategies
• lazy loading
• cascading update management
• lifecycle management
• Hibernate's interceptor layer
In addition, we'll examine the security considerations when using Hibernate. Often, single-credential data access isn't enough for sensitive data. We'll
walk through using per-user credentials for data access, logging security information about and through Hibernate, and accessing data sources through secure application servers.

By Justin Gehtland
Spring offers developers a simpler, more robust method for configuring applications. These benefits extend to security through the ACEGI framework. ACEGI makes the otherwise daunting task of securing your application logical and straightforward. More importantly, through its support for single sign-on provision through Yale's CAS system and its ability to provide instance-level authorization, Spring extends the common security model of most J2EE apps beyond what they are traditionally capable of.




In this session, we'll explore:

• configuring ACEGI to authorize against an in-memory user list, a database, and a JAAS login module

• page level authorization

• method level authorization

• instance level authorization

• forcing HTTPS connections to secured sites

• impersonation using the RunAsManager

By Justin Gehtland
Learn to use Spring AOP, aspect injection. and AspectJ integration.

Spring provides powerful support for Aspect-Oriented Programming (AOP), via

Spring Advisors
Dependency Injection for Aspects
Integration with AspectJ

In this session you will learn to use Spring AOP in real-world settings. We'll start with the basics of programmatic pointcuts, advice, and joint points. Then, we'll integrate these into the application Spring-style, using Dependency Injection.

With the basics out of the way, we'll move to meatier questions, including:

How (and when) should I step up to AspectJ?
How are Aspects implemented, and what are the performance implications?
What are the alternatives to Aspects?

Attendees will get more out of this presentation if they have a basic knowledge of Spring and Dependency Injection.

EJB3 (JSR-220) offers some great improvements over the prior EJB specs in terms of development simplicity and new features. In this session we will explore in detail some of the new features of the core EJB 3 specification. Included in this session will be a hands-on discussion and demonstration of session beans, dependency injection, interceptors (aop), and Message-Driven Beans (MDB). For the interceptors discussion I will be showing how to define interceptors for enabling a method trace, mocking objects, and sending JMS message notifications to be later picked up by the MDBs I will be creating. During the session I will demonstrate the new features of EJB 3 through interactive coding examples. Note: this session does not cover the new Java Persistence API (JPA) - only the core specification.

Agenda
- Introduction
- Constructing and Accessing EJB 3 Session Beans
- Dependency Injection
- Interceptors (AOP)
- Method Trace
- Mock Objects
- Sending JMS Message Notifications
- Message-Driven Beans (MDB)
- Using XML over Annotations
- Summary and Discussion

By Mark Richards
In addition to providing a simplified API, the new EJB3 specification (JSR-220) defines a standard ORM Java Persistence API (JPA) that is rapidly gaining in popularity. As you will see in this session, JPA bears a striking resemblance to popular ORM solutions like Hibernate and Toplink. In this session we will explore in detail the new Java Persistence API offered by JSR-220. We will start by discussing the overall design and architecture of the JPA and how the major components within JPA interact. We will then look at defining mapping objects (entities) and how to use the EntityManager to manage these entities. Through interactive coding examples we will investigate the pros and cons of detached entities and merging, how to map and use entity relationships (1-1, 1-N, N-1, and N-N), discuss Lazy Loading, and finally see how to use XML mappings rather than annotations. More advanced features of JPA will be covered in a separate session.

Agenda
- Introduction
- JPA Framework Overview
- Defining and Mapping Entity Objects
- Managing Entity Objects (EntityManager)
- Detached Entities and Merging
- Entity Relationships
- Lazy Loading
- Using XML Mappings

There has been a significant amount of buzz in the community and industry about the definition and role of an Enterprise Service Bus (ESB), particularly within the area of Service-Oriented Architecture (SOA). In this product-agnostic high energy session we will take a step back and consider whether we really need an ESB. Through real-world application and architecture scenarios we will see where an ESB would be helpful and where it would be overkill. We will take a look under the hood and find out just what an ESB is really doing, and take a quick look at JBI (JSR-208) and see the impact it has on the ESB worls. Then, using product-agnostic coding examples we will learn what an Enterprise Service Bus is supposed to do, then answer the question about whether the ESB is just a bunch of hype or if we really need it.

Agenda
- Introduction
- Handling Distributed Services Today
- ESB Alternatives

Tired of dealing with EJBs but cannot use other frameworks like Spring? How would you like to replace all of your remote Stateless Session Beans with POJOs and still access them remotely within Java EE? By using the Java EE Command Pattern we can write EJBs as POJOs and solve many of the issues facing EJB, including testability, configuration complexity, and performance, and still remain within the boundaries of the Java EE container. The Java EE Command Pattern is a simple pattern that can significantly reduce the complexity of large-scale Java EE enterprise applications. In this session we will explore the numerous issues facing a typical EJB architecture and learn how the use of the Java EE Command Pattern can solve these issues. We will walk through the different design alternatives and see how the command pattern is implemented in both EJB3 and in Spring. Through interactive coding examples you will learn what components make up the Command Pattern framework and what simple coding changes are required to convert a complex remote EJB-based application to a much simpler remote POJO-based application.

Agenda
- Issues with J2EE
- Java EE Command Pattern Introduction
- Java EE Command Pattern Core Components
- The Command Pattern Framework Implementation (EJB)
- The Command Pattern Framework Implementation (Spring/RMI)
- Applying the Command Pattern to a Typical EJB Application

This session describes the use and workings of Selenium, the open source web user interface testing tool.

Selenium is one of the most powerful functional testing frameworks to come from the open source world in a long time. This session covers all aspects of Selenium, starting from its origins as an internal user-acceptance testing tool through testing Ajax applications. This session covers Selenium functionality, syntax of the test scripts (both HTML and the scripting language), keywords, testing techniques, recording tests, creating extensions, and testing Ajax applications. Selenium is the premiere testing tool for Ajax, so I show several examples of the power of Selenium combined with Ajax.

Key Session Points

• Selenium origins and background


• Installation


• Building tests


• API overview


• The Selenium IDE


• Testing Ajax Applications


• Future directions

A lot is happening in the field of Aspect-oriented programming (AOP). AspectJ and AspectWerkz, the two leading AOP implementations, have merged, bringing in their respective strengths. The merged version, AspectJ 5, adds many new features aimed at simplifying writing and deploying aspects. The new features include an annotation-based and XML-based syntax to define aspects, support for new Java 5 concepts, and load-time weaving. The tools support for AOP continues to improve, as well. Further, the most popular IOC framework, Spring, enables integrating aspects written in AspectJ. There is also serious discussion and preliminary work going on to support AOP right into the VM itself. All in all, there is a lot to learn about the changes in the exciting field of AOP. This session is designed to help you get up to date with all these changes.

This session provides a guided tour of the new things in the AOP world. It explains new features in AspectJ along with the practical considerations in utilizing each of them. The presentation explores the fundamental synergy between AOP and metadata to understand right (and wrong) utilization of metadata-based crosscutting. Load-time weaving (LTW) enables adding aspects to your existing applications deployed in any application server with a minimal effort. The presentation shows how to utilize LTW to improve your productivity considerably, even if you don't yet subscribe to the AOP philosophy and don't want to use AOP in production. The presentation also demos the latest AspectJ Development Tool (AJDT) in Eclipse (that has improved a lot) to make Java developers feel home when developing with aspects. The presentation includes many demos to reinforce the concepts learned, as well as give a feel for what it would be like to apply aspects written using new features.

This session is particularly targeted at developers with good familiarity with AOP concepts and the AspectJ language. It is recommended to attend the “Introduction to Aspect-oriented programming with AspectJ” session or read articles and/or books that introduce AOP and AspectJ to obtain the prerequisite.

Enterprise application development is a gold mine for applications of AOP. There are many crosscutting concerns found in a typical enterprise application, ranging from well-known security and transaction management to application- and technology-specific concerns. Using AOP leads to implementations that are easy to understand and easy to change.

This session shows how to address common problems faced by typical enterprise applications, with a focus on web applications using AOP. It will present examples of applying aspects to persistence, business, and web layer. It will show how to apply aspects synergistically with technologies such as Hibernate, JAAS, JMX and Spring. Many of the examples include reusable portions enabling them to be readily used in your own application.

This session is targeted at developers with familiarity with AOP and enterprise applications. It is recommended to attend the “Introduction to AOP with AspectJ” session or read articles and/or books that introduce AOP and AspectJ prior to attending this session.

Ever wondered if you can automate testing of your web application, but couldn't produce a satisfactory solution? If so, this is the session for you! Attend this session to understand the alternatives you have for unit and functional testing of web applications.

Testing a web application is a complex task. You must not only ensure that each unit is working as expected, but also ensure that your application works correctly on all target browsers and operating systems. The sad fact is that not all browsers behave in the expected, standards-compliant manner. Performing all tests manually is not only cumbersome, but also error-prone and expensive. This necessitates automated testing of the application inside all relevant browsers. With the increasing use of Javascript and AJAX, automated functional testing is becoming even more important.

This presentation will show strategies for testing web applications. It will cover both unit testing as well as functional testing. For unit testing, it will discuss the mock object approach. Since unit testing is necessary, but not sufficient, the presentation will discuss tools available for functional testing. It will also study a specific tool -- Selenium -- that simplifies functional testing. During this session, we will do live coding to solidify the concepts learned.

J2EE has become the main new platform for enterprise application deployment. Good performance is an important business requirement. Supporting this requirement needs application profiling during the development phases and performance monitoring after application deployment. Come to this session to understand challenges and choices in monitoring J2EE applications.

Performance monitoring solutions must work under constraints imposed by the environment. Further, they must balance conflicting requirements such as overhead vs. richness of information. All of these need careful understanding of both requirements and solutions as well as the costs of any tradeoff decisions.

This session presents various tools and techniques available for monitoring J2EE applications. We will consider requirements of performance monitoring solutions in different scenarios. We will also discuss underlying enabling technologies such as Java Virtual Machine Profiling Interface (JVMPI), Java Virtual Machine Tool Interface (JVMTI), JFluid, JMX, design patterns, and aspect-oriented programming (AOP). During the session, we will demonstrate many of the tools and technologies discussed.

Mark Twain once said, "Everyone talks about the weather, but nobody does anything about it." Do you feel the same way about Unit Testing? Are you actively testing your code, or are you just thinking about testing your code... some day... once you get some more free time...

Unit testing offers benefits beyond the obvious. A happy side effect of writing unit tests is that your code ends up being better architected. By forcing you to be a consumer of your own code outside of the context of the main application, you end up seeing your code in a different light. Hidden dependencies get flushed out early. Good unit tests force your code to be more loosely coupled and highly cohes
