Unable to rollback using BMT in a stateless bean

Question

Hi,
My stateless bean contains the following testing code
UserTranaction ut = null;
try{
ut = context.getUserTransaction();
ut.begin();
// get database connection from OracleDataSource
// via container
// update a recored in db
if (true)
throw new Exception();
ut.commit();
} catch (Exception e){
ut.rollback();
} finally {
// close connection
I am using oracle 817 jdbc driver and when I execute the method,
the changes in DB are not rolledback and there is no exception
thrown. My questions are
1). Is BMT really work in oc4j? Anyone try before?
2). Is there any additional conditions/setting need to be done
in order to make BMT work? such as dataSource setting, database
configuration...
3). Could anyone provide sample code with related settings?
(especially what datasoure u are using)
Thank you very much!!!

Have you already tried to load the class like this:
Thread.currentThread().getContextClassLoader.loadClass(actionName);
Instead of using the same classloader that loaded your bean implementation, it uses the classloader given to the executer thread as the context classloader.
(In many cases this will be the same, but I don't know how this is done in the implementation of your container).
