Hi friends:) i have 2 jboss instances: jboss A (4.2.3) running on interface 127.0.0.1 and deploying some session beans jboss B (5.0) running remotely on other network interface and deploying a MDB The MDB can read message from remote topic on A If i try to use the create method of a session bean on jboss A, i have a SecurityException: java.rmi.AccessException: SecurityException; nested exception is: java.lang.SecurityException: Insufficient method permissions, principal=null, ejbName=SourceServiceBean, method=create, interface=HOME, requiredRoles=[ENABLED, SUPEROWNER, INITIALIZER, INDEXER], principalRoles=[] There is something to add about JAAS, maybe in a jboss config file, but i don't know where.
