Summary: Null Exception in abstract accessors
Initial Comment:
When using CMP2.0 defined accessors a Null Exception
is returned:
java.rmi.ServerException: RemoteException occurred in
server thread; nested exception is:
javax.transaction.TransactionRolledBackException: null
Embedded Exception
null; nested exception is:
javax.ejb.EJBException: null
Embedded Exception
null
Code sample:
public abstract class ThingBean implements
javax.ejb.EntityBean
{
. . .
public abstract String getName();
public abstract void setName(String name);
. . .
}
public interface ThingHome extends javax.ejb.EJBHome
{
public ThingRemote create(java.lang.Integer id)
throws
java.rmi.RemoteException,javax.ejb.CreateException;
public ThingRemote findByPrimaryKey
(java.lang.Integer pk)
throws
java.rmi.RemoteException,javax.ejb.FinderException;
}
Workaround:
Transaction must be expicilty set to 'Required' in the
<container-transaction> of the ejb-jar.xml deployment
descriptor. I cannot find if this the Transation=
Required attribute is a requirement of the EJB2.0
specification...if it is arequirement of the
specification, this is not a bug, but the workaround
should perhaps be mentioned explicitly in the CMP
documentation.
