Hi All,

I am trying tod deploy a CMP on JBoss4.0.2 and mysql 4.1.13 as backend.
The bean gets deployed fine and the tables are also created.
But when I try to create a record in the database I get the following exception.

12:38:45,531 ERROR [LogInterceptor] TransactionRolledbackException in method: public abstract com.cygnet.medina.Hospital.Hospital com.cygnet.medina.Hospital.HospitalHome.create(com.cygnet.medina.Hospital.HospitalData) throws javax.ejb.CreateException,java.rmi.RemoteException, cau
