There is a problem while compiling

I have exactly done what is to be done in running the EJB program for Reading&running XMl files with EJb but getting 34 errors while compiling the java files in session folder, I checked each way--
errors like javax.ejb.EJBHome not found, package com.stardeveloper.ejb.session not found etc etc. Please mail back why the errors are coming even after I noted & checked the path of the project.

Thanks,
Sumantto.
