Hi All,


I am facing problem while using entity bean to store some data in oracle(8i) database.I have made necessary changes in default.properties file and copied classess111.zip under system directory.. During deloyment or while compiling we didn't face any problem.It is giving me "principal mapping error in j2ee server window" while I try to execute my client program.In the client window it is raising a remote exception stating entity beans couldn't be created. I got stuck and could'nt find a way to proceed.Please help it's urgent
