Re: [rules-users] Exception using persistence





I did, but I get the same Exception as before, but on this new line


UserTransaction ut = (UserTransaction) new  
InitialContext().lookup("java:comp/UserTransaction" );

I still don't understand where the "java:comp/UserTransaction" will be  
accessible/come-from/being-created ... ?
