My EJB client is in separate EAR and separate server from one running EJB and there will be distributed transaction. -------------------------------------------------------------- Reply to this message by going to Community [https://community.jboss.org/message/766425#766425] Start a new discussion in JNDI and Naming at Community [https://community.jboss.org/choose-container!input.jspa?contentType=1&...]

Only when I do PortableRemoteObject.narrow(), it just returns null. there is no classcastexception or any other exception. Do I have to include any jboss descriptor file in my EJB Client jar, currently it only has remote and home interfaces. Websphere doesn't need any special descriptor file and stubs get generated during deploy time. When I deploy the ejb client jar from my websphere server (which has stubs in it) in JBoss, I no longer get null but Home object is returned. So, I suspect it is something to do with missing stubs or dynamic stub not working in Jboss due to some reason. Look forward to your help. -------------------------------------------------------------- Reply to this message by going to Community [https://community.jboss.org/message/766452#766452] Start a new discussion in JNDI and Naming at Community [https://community.jboss.org/choose-container!input.jspa?contentType=1&...]

I also tried doing lookup from java main test method and also get null after doing PortableRemoteObject.narrow() I see 4-5 posts on this very issue but nowhere has anymore mentioned the resolution which seems suprising to me. Do we need to decorate EJB client with some JBoss descriptor file or setup some security or enable dynamic proxy? Is there a workaround to generate static stubs for RMI/IIOP somehow because when I deploy my Websphere client jar (with stubs in it), narrow works fine and gives me Home reference back. -------------------------------------------------------------- Reply to this message by going to Community [https://community.jboss.org/message/766729#766729] Start a new discussion in JNDI and Naming at Community [https://community.jboss.org/choose-container!input.jspa?contentType=1&...]

I read somewhere you have to setup java.policy and enable security when starting servers using command line. Please note my EJB's are not secured and there is not a business requirement for same. Also note that I am using JBoss 5.1 GA for both client and EJB servers? If security needs to be setup, can you please send me information on same. 2) Do we have to include some jars on client jvm's classpath specifically? If so, which jars? 3) Does EJB client project needs to have some client descriptor file? Currently it only has EJB remote and home interfaces. -------------------------------------------------------------- Reply to this message by going to Community [https://community.jboss.org/message/771540#771540] Start a new discussion in JNDI and Naming at Community [https://community.jboss.org/choose-container!input.jspa?contentType=1&...]
