Guice (pronounced 'juice') is a Jolt award-winnning, lightweight dependency injection framework for Java 5 and above. Put simply, Guice alleviates the need for factories and the use of new in your Java code. Think of Guice's @Inject as the new new. You will still need to write factories in some cases, but your code will not depend directly on them. Your code will be easier to change, unit test and reuse in other contexts.

Lombardi Blueprint is a browser based business process documentation and diagramming tool written using GWT and Java. It supports simultaneous viewing and editing of process definitions by multiple users in different locations with multi level undo and a rich editing experience including drag and drop, inline editing and, automatic diagram layout. Implementing these features presented several technical challenges.

Damon and Alex will describe two of the most interesting: 1) synchronizing multiple client object models with the server, and 2) providing a highly responsive diagram editing experience.

Creating a complex user interface poses particular performance problems using today's javascript engines over what can typically be performed with a native Java VM. The two main challenges we faced with our process diagram were speed of rendering in the browser and automatically laying out and routing large diagrams. Efficient rendering requires us to use a flyweight pattern to handle large html documents, while layout and routing dynamically switches between client and server execution depending on the time required to layout the diagram.

To support multi user editing and viewing Blueprint must keep client and server object models in sync. Our repository design supports doing this efficiently by only requiring us to transfer the differences between two model states in either direction. This same approach allows us also to support rollback to previously saved versions by having the server compute the set of commands required to move between any two states.

The long-awaited second edition of Effective Java is here! It covers the latest in best practices for the Java platform. This presentation will concentrate on three areas where new material has been added to the book: enum types, generics, and concurrency. Do you want to know how to combine the safety and richness of collections with the performance of bit fields? Have you ever been confused by wildcard types? Do you want to know when and how to use lazy initialization? Then come to this talk. The patterns and idioms you learn will be directly applicable to your programs and designs.

What do you do when you want the benefits of modularity and abstraction during development, but you aren't willing to subject users with any runtime overhead to get it? If you're the GWT team, you invent deferred binding. Deferred binding is a pluggable compile-time type substitution and code generation mechanism. This unique approach to program modularization provides many of the benefits of Java reflection and dynamic class loading without compromising the GWT compiler's ability to optimize the heck out of your code.

In this Code Lab, we'll examine how the GWT libraries leverage deferred binding and GWT compiler optimizations to provide zero-overhead browser abstractions, highly optimized internationalization, automatic image bundling, and high-performance, polymorphic RPC. Did we mention that deferred binding is extensible? We'll also use deferred binding to create a new library from scratch.

You may already know about GWT's nifty JavaScript Native Interface (JSNI), which allows you to define native Java methods with handwritten JavaScript. In GWT 1.5, there's an even more powerful way to program close to the metal. You can now model arbitrary JavaScript types directly as Java classes (specifically, as subclasses of GWT's JavaScriptObject class), yet there is no overhead in size or speed. You can code against any JavaScript object as if it were a regular old Java object. So, what does that buy you?

• It's never been easier to integrate with external JS libraries; just define a Java class that models the JS object you want to interact with. Nice Java syntax, no overhead.
• Freely use low-level native JS data structures (JS arrays, for example) by exposing them with a Java-friendly API. You can even apply Java generics to JS types!
• Superimpose strongly-typed Java classes on JSON objects, giving you IDE code completion, refactoring and compile-time type checking.
• GWT uses this new ability to provide a complete cross-browser DOM class hierarchy based on the W3C's Java HTML bindings. Programming straight to the DOM has never been more productive.

Come learn about this unusual and powerful new capability that you can use to squeeze every drop of performance and interop out of your GWT projects.
