Hi Alessandro,
the code causing the CCE is
> 04/10/02 14:11:42 at > org.apache.ojb.broker.accesslayer.ConnectionFactoryAbstractImpl.newConne > ctionFromDataSource(C > onnectionFactoryAbstractImpl.java:195)
in this method OJB does: <snip> InitialContext ic = new InitialContext(); ds = (DataSource) ic.lookup(jcd.getDatasourceName()); <===!!! </snip>
So it seems that the object returned by the lookup is not instance of DataSource or it's a side-effect of another problem.
Could you describe your test more detailed? You lookup OjbPbFactory in ejbCreate method? And the DAO use an session bean or does directly access OJB via JNDI lookup?
regards, Armin

Hi all.
I have a transaction on my ejb method that call various DAOs.
DAOs access dB through OJB
I'm working with OC4J.
I've done a start up class similar to that in the documentation adapted
to OC4J

public interface OjbPbFactory{

If I do :
OjbPbFactory ojbFactory= (OjbPbFactory)context.lookup("PBFactory");
PersistenceBroker broker =
ojbFactory.getInstance().defaultPersistenceBroker();
In the ejbCreate() I don't have problems.
But If I put it in the Dao called by ejb I get the following error:

and the error on my code is on the line PersistenceBroker broker =
ojbFactory.getInstance().defaultPersistenceBroker();
I yet got sure that the problem is in . defaultPersistenceBroker() and
not in .getIstance.
In other word I get the PersistenceBrokerFactoryIF rightly, but I fail
when trying to get the PersistenceBroker
Can AnyOne help me?
What I wnt to do is to have a rollback on all Dao if anyone fails.
Thanks in advance.
