I've been a problem with find methods (CMP 2.0). I wrote a enity bean with some finders methods that returns a Collection. When this methods returns only one object in Collection works fine. When find()* methods returns more than one, a excpetion is throw:
09:40:31,691 ERROR [LogInterceptor] EJBException:
javax.ejb.EJBException: Unknown load group: name=group name
at org.jboss.ejb.plugins.cmp.jdbc.bridge.JDBCEntityBridge.getLoadGroup(JDBCEntityBridge.java:490)
(etc...)
------------------------------------------
Iterator i = home.findByName("arg").iterator();
while (i.hasNext()) {
Product prod = (Product) PortableRemoteObject.narrow(i.next(), Product.class);
System.out.println(prod.getName()); // the exception occurs here
}

PostgresSQL 7.3.3
