getting java class names/javadocs for generated classes

Hello, I performed scomp on my xml schema and got a jar file out of it.  However, I do not know where to go next.  How do I get a list of the java class names and methods for the generated classes?  How do I get the javadocs?  

I suppose I can generate the source code and try to do a separate javadoc command on that, but really wish there is an easier way.
