I'm enable to compile the zimbra source code. There is an error saying cannot find the main method.. I want to know whether there is a way to edit and re compile the code as I wish.. and any I IDE is there to use for it..

and I want to run zimbra open source edition in tomcat server in localhost.. because I want to edit the open source edition according to our system.. and modify the system as well.. but I was enable to find the Information about that..

Anyway I was thinking on editing all the interfaces of zimbra open source edition.. and If some one knows about finding the source code of interfaces please help me to do my works.. because this is an academic purpose.

thank you..
