Accessing Java API information with Python

Question

I'm looking for a very simple way, from Python, to get information about Java classes:

name of the class
what it extends and implements
methods with returns types and parameters
attributes with type information

Basically all of the information you'd need to generate a javadoc.

Is there an existing Python library that can get me this information either for a .java or .class file, doesn't matter. I'd probably even be okay with something that gets this information from a javadoc.

I know there is javaclass library but that is overkill for what I'm looking for.

Just want to make sure something doesn't already exist like this before I implement my own.

What I'm looking for could easily not be a project on its own but a one-off script someone has written. Also, google is not perfect, there are plenty of tiny libraries out there that are almost impossible to find by googling. — Lex Berezhny

@lex: Maybe I am misunderstanding the question. How do you expect to find to these small scripts (in order to analyze them), if not via some search tool? — blubb

@Mark yes, but that is the last resort, I don't want to be dependent on Jython. again, it seems overkill for just getting basic info. — Lex Berezhny

If your Python code does not make much use of C based libraries you could run the code in Jython which is Python run on the Java VM.

Otherwise you could write a small Java/jython executable that gets the information and writes it to stdout to be read by a CPython program calling it.
