[jboss-user] [EJB 3.0] - Re: JBoss and PostgreSQL 8.1

Very Strange... As soon as I remove the line

@IdClass(ComponentPK.class)

and the @Id before the second part of the key everything runs fine. And the same happens with HSQL as DB: I get Exceptions if I use a composed primary key, but there is no error with a normal primary key.

The Problem is: I really need a composed primary key...
