I would like to know if this issue has been resolved. I encountered the same problem with my application and would like to know if it is an orion bug or an error in my datasources configuration. Here is the run down: Same method in a session bean does this (simplified here): Contact contact = contactHome.create(contactData); contactHome.findByPrimaryKey(pk) // WORKS FINE contactHome.findByUsername(username) // Finder Exception Please let me know if there is a solution for this problem. ----------------------------------------- Eduardo Estefano Integrated Information Systems 480.317.8549
