UML to Java code generation tool

I have recently been looking for a tool to generate Java code from a UML diagram. I have already looked at Papyrus and Omondo for Eclipse. The problem I am having is that the tool is needed in a number of projects that are loaded with JPA and JAXB classes. This makes both Omondo and Papyrus come up short, as annotations and getter/setters are fairly important. What I am looking for is a tool that is able to maintain a graphical class diagram of these projects, like a UML diagram, and then translate that into Java code as needed.

What I am looking for is a reliable Class diagram -> Java code tool, preferably UML based, that supports (as many as possible of) the following:

Java primitives (and wrappers)
Annotations on methods and attributes
Referencing of Java core classes in class diagram
Easy getter/setter method generation
Coding directly in the defined methods

If anyone knows of a tool (it doesn't have to be UML class diagrams) I would very much like to know about it.

Solution

As for me the greatest UML tool is ArgoUML. It is very powerful. Based on Java. It constantly improved and become more and more useful tool.
