    lookup

    muaddib

      When I try to lookup an entity bean that I have created, with the command : ctx.lookup("film");

      I receive the following exception :

      javax.naming.CommunicationException. Root exception is java.lang.ClassNotFoundException: org.jboss.ejb.plugins.local.LocalHomeProxy (no security manager: RMI class loader disabled)

      Why?

          Assuming you are doing this lookup from a client program external to jboss make sure you have the jboss.jar on your classpath.

            I also am experiencing the same error however when I add the jboss.jar to my path I recieve a new error stating,

            I'm sorry for the length of the stack trace. This error occurs specifically when I do a lookup on a local bean. Remote beans seem to work fine.

            Any advice would be appreciated. I am new to J2EE and am finding this very discouraging.

                That is the jboss jars, from jboss/client

                  Local beans/interfaces can only be used from within the same JVM. Since your client is an external program (at least it sounds like that) it can only use the remote interface.
