Guice (http://code.google.com/p/google-guice/) is a lightweight dependency injection (DI) framework, alleviating the need for hand-written factories or use of the Java "new" keyword. Guice makes the provocative claim to being the new "new". Guice differs from Spring in it's approach to DI - Guice eschews XML configuration in favor of leveraging Java's native type-safety via Java 5 annotations and generics. But Guice need not necessarily be seen as a replacement for Spring; Guice has built-in Spring integration. In this presentation we will learn the basics of Guice, it's API and object model, via simple code exercises. We will also examine the options available to migrate existing code bases to Guice.

This talks assumes basic familiarity with Java 5 annotations and generics, as well as dependency injection.
