[jboss-user] [EJB 3.0] - Could not dereference object on Remote Server

Hi! I'm a newby in ejb3.0 and startet with the tutorials. The first step was testing the Stateful-ShoppingCart-Example. I used the JBoss4.0.4 (ejb3-installer) on a local machine - the same machine from where i started the client-app. >> everything works! The next step was using an 4.0.4-JBoss on an remote Server (Ubuntu 5.10). This Server i used already with jboss4.0.3 and ejbs2.1 and j2ee works with him. When I deployed the ShoppingCart.jar and tryed to run the Client from an remote win2000-pc i have this error: | Exception in thread "main" javax.naming.NamingException: Could not dereference object [Root exception is org.jboss.remoting.CannotConnectException: Can not get connection to server.
