QUESTION POSED ON: 10 September 2004
I am trying to implement an EJB with a LocalHome using JBoss:

HelloLocal Object refLocal = context.lookup("HelloLocal"); .......

But it throws an exception:

javax.naming.CommunicationException [Root exception is java.lang.ClassNotFoundException: org.jboss.ejb.plugins.local.LocalHomeProxy (no security manager: RMI class loader disabled)]
How can I solve this problem?

If you are NOT dynamically downloading the EJB stub, you need to make sure that the generated stub for the EJB is available locally, i.e. in the classpath.

If you ARE downloading the EJB stub dynamically, you need:

A) An RMISecurity Manager configured, as follows:

if (System.getSecurityManager() == null)
   {
      System.setSecurityManager(new RMISecurityManager());
   }

B) Your client must also have sufficient access through the appropriate socket.

C) You need to add file download permission in your client policy file, as follows:

grant codebase someURL { permission java.io.FilePermission "/path/to/downloads", "read"; };

D) Then your client must be started as follows:

java -Djava.security.policy=java.policy com.yourpackage.yourclient
