I can't, Evan, since I've already commited the transaction. The code in the
session bean goes like this:
UserTransaction ut = null;
try {
BMPDataBean dataBean = getHome().findByPrimaryKey( pk );
ut = m_context.getUserTransaction();
ut.begin();
dataBean.setXXX ( xxx );
dataBean.setYYY ( yyy );
ut.commit();
}
catch (EJBException e) {
e.printStackTrace();
}
catch (NamingException e) {
e.printStackTrace();
}
catch (Exception e) {
e.printStackTrace();
}
The thing is when the session bean commits, the container executes ejbLoad -
wich fails when the version is incorrect.
Throwing EJBException doesn't prevent the commit. I need the commit to fail
under some circumstances, I jus't don't find the way to make it fail.
