How to generate UML diagrams from java source code

I want to create good documentation of the classes and their relationships in my Java project but without drawing it all by myself. And if there are changes in the future it would be great if it can be automated. After a brief search and trying different products, eUML2 Eclipse plugin seems quite nice for this purpose.

Testing applets without a browser

I don’t like applets. They are troublesome and slow. But that doesn’t change the fact that sometimes I still have to work with it.
