I have found the work around for such scenario, In JBoss, unlike Weblogic, you cannot deploy same local ejb with same local jndi name across multiple ears. ( However this is nowhere specified in ejb specification ). Work around for such scenario in JBoss is, While deploying local ejbs in JBoss, dont specify the jndi for ejbs ( i.e. Remove the jboss.xml file ). Server will assign a random jndi name to it. Make use of ejb-local-ref in web.xml, just configure the ejb you want access in web.xml <ejb-local-ref> <ejb-ref-name>MySession</ejb-ref-name> <ejb-ref-type>Session</ejb-ref-type> <local-home>mySessionlocalHOme</local-home> mySessionLocal <ejb-link>MySession</ejb-link> //give the same name here ( ejb name ) </ejb-local-ref> This you have to do it in all ear files.
