[kepler-users] Understanding Kepler at Java Level

[ben leinfelder]

The webservice code is in the webservice module
http://code.kepler-project.org/code/kepler/trunk/modules/webservice/
I'm not sure exactly which class it is that does all the work, but  
there's a good introduction/help file in the module.
