anonymous wrote : InitialContext ctx = new InitialContext(); You will have to change this to pass the context information. That will help Tomcat know that you are looking for an object which resides on JBoss. | Properties props = new Properties(); | props.put(Context.INITIAL_CONTEXT_FACTORY,"org.jnp.interfaces.NamingContextFactory"); | props.put(Context.PROVIDER_URL,"jnp://localhost:1099"); | | Context ctx = new InitialContext(props); Also, make sure that you add the jbossall-client.jar file (present in %JBOSS_HOME%/client folder) to the lib folder of your WAR in Tomcat.
