Eclipse how to generate UML diagrams from code

Question

Is there any Eclipse plugin capable of generating UML diagrams from Java code ? I know about some of them but the point is that they all generate Class Diagrams from Code. The point is that I wanted to generate some other diagrams as well (for example: DFD - Data Flow Diagram) If impossible just tell me about it - I will live with it...

Solution

There are many plugins for that for that. One plugin that I really like is ObjectAid: http://www.objectaid.com/
