hello
i use combination of jbuilder6 and bes5 to develop ejb,i write a session bean as facade to call a entity bean that map to a table(named "jobs") in my database(sqlserver2000),then use the "test client wizard" of jb6 to generate a test client,in the client,i call a method of the session bean to retrieve a field from the table through the entity bean.
my entity bean:com.mansion.ejb.entity.jobs
my session bean:com.mansion.ejb.session.TableViewer
but throw follow exception:

Throwing TransactionRolledbackException for the method: public abstract com.mansion.ejb.entity.JobsRemote com.mansion.ejb.entity.JobsRemoteHome.findByPrimaryKey(java.lang.Integer) throws java.rmi.RemoteException,javax.ejb.FinderException
