Generate UML Class Diagram from Java Project

Question

Is there a good tool that can help to reverse engineer Java classes to UML that will show an overview of how my classes are related to each other  It doesn t need to decompile from JAR file because I have the sources  I know there are quite a few out there but most of those can only generate individual class  I hope there is a tool that can generate class diagram that shows an overview of how all my current classes and packages work together  so that I can analyse my current architecture design  Of course  analysing is one thing  The other is for documentation purposes    I know of a few so far  But they cannot do an overview class diagram  Here s a list of Java UML tool that I have tried and is capable of doing reverse engineer but cannot do an overview class diagram of my whole project    StarUML  Really good Opensource UML tool but cannot generate not overview class diagram  ArgoUML  It is slow and sluggish and it keeps crashing  UModel  This is a commerical software  I used before some time ago but found it difficult to use  MS Visio  It doesn t support Java UML reverse engineer  Only for VB    Are there any other recommendations to add to this list  And hopefully  can generate an overview Java class diagram  I am using Eclipse  by the way

I wrote Class Visualizer  which  does it  It s free tool which has all the mentioned functionality - I personally use it for the same purposes  as described in this post  For each browsed class it shows 2 instantly generated class diagrams  class relations and class UML view  Class relations diagram allows to traverse through the whole structure  It has full support for annotations and generics plus special support for JPA entities  Works very well with big projects  thousands of classes
