Hola, I'm developing a web service with EJB3 and I kind of have some difficulties with all the persistence thing... I have a session bean Process which accesses a bean Query. This beans contains all the queries for the db hence the EntityManager. The deploy is ok, but when calling the web services which requires user identification and therefore a call to the db, the following error is thrown : | 2008-05-27 15:46:29,615 ERROR
