Hi there,
I have a really simple bean and test for that bean. I'm building the test gradually.
I've included what I have so far. The problem is that although the bean is created,
findByPrimaryKey() never finds any beans and findAll() always returns 0. If I try to
create the bean again though, the bean is already there and a ServerException is
thrown. (BTW, why a ServerException? Should it not be a CreateException?).
The error from the line:
Message beanByPK = _home.findByPrimaryKey(new Integer(1));
is:
[java] javax.ejb.ObjectNotFoundException: No such entity!

The error from the line:
Message beanByPK = _home.findByPrimaryKey(new Integer(1));
is:
1)
testCreateMessageBean(client.uk.org.objectwiz.model.forum.ejb.TestClient)junit.framework.AssertionFailedError:
[TestClient.removeAllBeans()] number of beans: 0
But if I try to insert the bean again, the error is:
[java] java.rmi.ServerException: RemoteException occurred in server thread;
nested exception is:
[java] javax.transaction.TransactionRolledbackException: INSERTING AN ALREADY
EXISTING BEAN, ID = 1; nested exception is:

Can anyone shed any light on this?
