Reverse Engineer sequence diagram in StarUML

I am in the process of reverse engineering an existing java project. I am using StarUML to generate the class diagrams.

I would like to know how I can generate a package diagram, package dependency diagram and sequence diagram from existing code in StarUML? I would be much interested in sequence diagram if not the others. Could you please l开发者_运维百科et me know about it?

I would also like to know if you have come across any other better open source tool that does this job. Thanks a bunch for your time.

Thanks, J

Although I am not familiar with StarUML ... well there is a tool named BinaryDoc looks can generate the desired diagram. BinaryDoc is trying to generate the diagrams based on the meta data in the binary files, like Java .jar/.jmd and .class files.

class diagrams

Here is an sample of class diagram for java.lang.ClassLoader

package dependency diagram

Here is an sample of Java package diagram for java.sql
