Error #300 JBuilder7

Hi,
I recently started working JBuilder 7. What i am trying to do is compile an already developed package. So i figured all i have to do is do the project settings right and set the classpaths and i am set to go.
But by nightmare started just there, when i try to Make/Rebuild its giving me the following error
"ding.java": Error #: 300 : class dong not found in class com.server.ding.dong at line 51, column 40

I tried looking up in the forums in here and other places, some say you have to add required libraries and all but in here both the classes ding and dong are in same package so it should check the dependencies and compile it. But it doesnt.
Can somebody throw some light and guide me.
Regards,

Your answer is in your error message. Are you trying to save the file as Ding.java and declaring it Dong in the Class?

For a start i am not a beginner and am not trying some examples here. I have a package, that has been developed by me and deployed too.
I am testing JBuilder as it gives me UML diagrams at the class level and lets me save them.
If you see the error msg it says that a class A cant find another class B, meaning class B is being used somewhere in class A.
To clear things up, class B is imported in class A. So there shouldnt be any problem. The same piece of code runs in all IDE's, so i am sure there's some wierd setting that JBuilder needs me to do.
I am using JBuilder 7.
