I have an web application that have a part running with TWINCAT. TWINCAT sends messages to an message driven bean wich talks to an ejb. This ejb must read or update the database.
The application is working correctly when that must read, but update a row is impossible, and there are no error messages. It seems like an permission denied problem, cause i don't execute the mdb from the controller. (if i do this, work).
Application dont update the database when the method is executed by a message.
