I believe if you throw a checked exception from your method you will need to
set rollback, if you throw an unchecked exception like EJBException the
container should rollback the transaction for you.
Section 12.2.2 of the EJB 1.1 spec clearly states -
The Container catches a non-application exception, logs it (which can result
in alerting the System
Administrator), and throws the java.rmi.RemoteException (or subclass
thereof) to the client.
The Bean Provider can rely on the Container to perform the following tasks
when catching a non-appli-cation
exception:
. The transaction in which the bean method participated will be rolled back.
. No other method will be invoked on an instance that threw a
non-application exception.
As for the settings I really am not familiar with weblogic stuff, you'll
need to read the docs to figure out if it's misconfigured.
Other issues to consider, where does it load the helper DAO object from, the
jar file or the system classpath? How do you get the connection (somebody
else mentioned you want a DataSource from weblogic's connection pool I
think)?

Hi Pooja,
I think u r missing soimething here. When you catch an
Exception you need to do an explicit rollback on the
Context.
I hope this takes care of your problem.
