Hi ! I hope I understand your problem, and I hope I can provide some help ;-). You have deployed the same bean in different ejb JARs, but your client lookup does not seem to find the bean which "belongs" to it ? I thought this should not be possible at all ;-). Well, you can control the JNDI names with jboss specific deployment descriptors. For each bean in an EJB jar you can specifiy to which JNDI name it should be bound: <?xml version="1.0" encoding="UTF-8"?> | <!DOCTYPE jboss PUBLIC | "-//JBoss//DTD JBOSS 4.2//EN" | "http://www.jboss.org/j2ee/dtd/jboss_4_2.dtd"> | <jboss> | <enterprise-beans> | <session> | <ejb-name>DataManagerBean</ejb-name> | <jndi-name>DataManager1</jndi-name> | <local-jndi-name>DataManager1Local</local-jndi-name> | </session> | </enterprise-beans> | </jboss> This will redefine the global JNDI name of the bean (defaults to EARName/EJBName/local). On the client side, an ENC entry will be defined in jboss-web.xml and references the new JNDI name: <?xml version="1.0" encoding="UTF-8"?> | <!DOCTYPE jboss-web PUBLIC | "-//JBoss//DTD Web Application 4.2//EN" | "http://www.jboss.org/j2ee/dtd/jboss-web_4_2.dtd"> | <jboss-web> | <context-root>...</context-root> | <ejb-ref> | <ejb-ref-name>ejb/DataManagerBean</ejb-ref-name> | <jndi-name>DataManager1</jndi-name> | </ejb-ref> | </jboss-web> Hope this helps !
