Eclipse UML plugin with Java Code Generation

Question

Does anyone know of a good (read: Free) Eclipse UML plugin that can also do code generation? If not, does anyone know of any good Eclipse UML plugins?

EDIT

Answer 1

I've had some luck creating UML diagrams based on java code with ObjectAid: ObjectAid Download Page.

It was made for Eclipse so it should work. However, I don't know if it does code generation... but it makes a pretty picture!

The site lays out how to install it and the UML diagramming portion is absolutely free!

Hope this helped!
