Thanks - The Session bean, and all the entity beans are container managed. I've checked my deployment descriptors and they seem to be okay, but I still get exceptions passed back from an EJB that don't cause a rollback.

At the moment I just have it set up so that one of my Entity beans has a null PK, so it always throws and EJBException on creation.

In rough form the code looks like

public class CommandEngineEJB implements SessionBean {

public CommandResultIF execute(Command cmd) {
return cmd.execute();
}
}


public Class exampleCmd() extends Command {
public CommandResultIF execute() {
// EJB calls
cntx = new InitialContext();
UserAccountLocalHome userlocalhome = (UserAccountLocalHome) cntx.lookup(UserAccountLocalHome.JNDI_NAME);
UserAccountLocal user = userlocalhome.create(null);

}
}

And a snippet from the jboss deployment descriptor looks like ...
...
<container-transaction >

<ejb-name>CommandEngine</ejb-name>
<method-name>*</method-name>

<trans-attribute>Required</trans-attribute>
</container-transaction>
...

And the entity beans all have similar settings .....

Am I being really dumb?
