Hi,
I tried this on OC4J 9.0.3 production ( http://otn.oracle.com ) and Tomcat 4.0.1 (Catalina). I have a SF session bean deployed on OC4J, a web app deployed on tomcat. web.xml has ejb references added.
The code in first JSP is like this..
java.util.Properties prop = System.getProperties();
prop.put(Context.INITIAL_CONTEXT_FACTORY,
"com.evermind.server.rmi.RMIInitialContextFactory");
prop.put(Context.PROVIDER_URL, "ormi://localhost:23891/current-workspace-app");
prop.put(Context.SECURITY_PRINCIPAL, "admin");
prop.put(Context.SECURITY_CREDENTIALS, "welcome");
Context ctx = new InitialContext(prop);
HealthCareServiceHome h = HealthCareServiceHome)PortableRemoteObject.narrow(ctx.lookup("HealthCareService"),HealthCareServiceHome.class);;
HealthCareService js = h.create();
Handle eh = js.getHandle();
session.setAttribute("Eh",eh);
and in a second JSP, I access this stateful session bean like this...
Handle eh= (Handle)session.getAttribute("Eh");
HealthCareService s = (HealthCareService)eh.getEJBObject();
// do something on this instance. Everything works fine
I dont know what versions of tomcat/oc4j you are using, may be an upgrade will help?
Thanks,
