Wolf-Dieter Fink [http://community.jboss.org/people/wdfink] created the discussion "Re: Interoperability of EJB2/3 between JBoss EAP 4.3 and JBoss EAP 5.1.1" To view the discussion, visit: http://community.jboss.org/message/643604#643604 -------------------------------------------------------------- I would recommend to use both server with AS5.1. There are some difficulties with: - Transactions, you cant have Tx span both server/application - Security, works only if the applications are not JAAS secured (or you might handle the credentials in your application which is a mess) - classloader, because of different client libraries that you have to use So I give up to get this working because I can't get all things working -------------------------------------------------------------- Reply to this message by going to Community [http://community.jboss.org/message/643604#643604] Start a new discussion in JNDI and Naming at Community [http://community.jboss.org/choose-container!input.jspa?contentType=1&...]
