Has anyone see this problem? I have a orion server running on my NT box (JDK 1.3) and a client on the same machine. The client loops every 10 seconds and calls the same method in the CartEJB on the server. I've added a database lookup, etc to the CartEJB method. After about 125 exections I get this error on the client: java.lang.NullPointerException at aq.invokeMethod(JAX) at ah.invoke(JAX) at Proxy0.create(Unknown Source) at mikecart.test.CartClient.testOrion(CartClient.java:80) at mikecart.test.CartClient.main(CartClient.java:22) System/communication error: IO Error: Disconnected The actual line it is erroring on is: Cart cart = (Cart)PortableRemoteObject.narrow(home.create(), Cart.class); The ejbserver system traces do not show any errors. ======================================== Mike Fontenot - Object Systems Architect Polygon Network, Inc.
