Thank you for your reply wolfc. I have tried but i have always the same error at deployment : Reason: java.lang.RuntimeException: could not resolve global JNDI name for @EJB for container TestDAO: reference class: daosession.VerifJaguarHibernateEJB3DAO | ejbLink: not used by any EJBs TestDAO is an EJB which calls VerifJaguarHibernateEJB3DAO. If you have an idea, i will be very delighted. Regards, View the original post : http://www.jboss.com/index.html?module=bb&op=viewtopic&p=4046029#...
