How to compile Tomcat 4.0.3 with JBuilder?

[shi_hang]

I want to monitor the running of tomcat 4.0.3. 
As we known , JBuilder provides the such powerful functions like step , break point 
and so on.
But we must compile tomcat with JBuilder at first. Is there anyone can tell me how to 
compile tomcat with JBuilder?
Any help is appreciated.
