Running CMP EJB in remote OC4J fails, works in embedded. Oracle 9i

Question

I more or less followed the EJB Tutorial (in the help) for creating a session-entity bean facade from Oracle 9i tables. Everything executes correctly in the embedded oc4j but it fails on the remote oc4j with
java.sql.SQLException: Invalid column name
     at oracle.jdbc.dbaccess.DBError.throwSqlException(DBError.java:187)
     at oracle.jdbc.dbaccess.DBError.throwSqlException(DBError.java:229)
     at oracle.jdbc.dbaccess.DBError.throwSqlException(DBError.java:292)
     at oracle.jdbc.driver.OracleStatement.get_column_index(OracleStatement.java:5632)
     at oracle.jdbc.driver.OracleResultSetImpl.findColumn(OracleResultSetImpl.java:716)
     at oracle.jdbc.driver.OracleResultSet.getString(OracleResultSet.java:1506)
     at com.evermind.sql.FilterResultSet.getString(FilterResultSet.java:585)
     at EmployeeLocalHome_EntityHomeWrapper13.findAll(EmployeeLocalHome_EntityHomeWrapper13.java:1260)
Then I also created another simpler CMP EJB that just has 3 fields from Oracle table. This one doesn't even work in embedded oc4j :
com.evermind.server.rmi.OrionRemoteException: Database error: ORA-01747: invalid user.table.column, table.column, or column specification
     java.util.Collection TimesheetHoursHome_EntityHomeWrapper11.findAll()
Are there any known problems I should look out for with generating CMP EJBS with wizards?
I think the IDE is more intuitive than WSAD. It would be great it things worked though.
Another question is regarding relationships. Do the wizards always use ejb-refs to implement relationships? It should be easy enough to add them with EJB Editor if they do not.
Thanks for any help.

Known issues are documented in the release notes

<<<Another question is regarding relationships. Do the wizards always use ejb-refs to implement relationships? >>>>
Not sure what you meant here. If you reverse engineer let us say DEPT and EMP tables, foreign key relationships between the tables are reverse engineered as CMR but there aren't any ejb-ref/ejb-local-ref tags which get generated in the deployment descriptor.
<<It should be easy enough to add them with EJB Editor if they do not. >>
You can double-click on the EJB to bring the EJB Module Editor and select "Relationships" node to add/edit/delete relationships visually.
