Error Accessing EJB from remote application - is it supported in 101202?

Question

We are running Oracle App Server 10.1.2.0.2, There is a containers created on midtier server called OC4J_TEST .
We have two applications, one has EJB and another one has JSP.JSP has following code
Hashtable env = new Hashtable();
env.put(Context.INITIAL_CONTEXT_FACTORY, "com.evermind.server.rmi.RMIInitialContextFactory");
env.put(Context.SECURITY_PRINCIPAL, "ias_admin");
env.put(Context.SECURITY_CREDENTIALS, "welcome1");
String pURL="opmn:ormi://localhost:12401:OC4J_TEST/";
env.put(Context.PROVIDER_URL,pURL );
env.put("dedicated.connection","true");
Context context = null;
sampleejb Sampleejb;
String mess = "Initial message, if you see that is because EJB has not been properly called";
mess = mess + " "+pURL;
try
// Create InitialContext
context = new InitialContext(env);
// Lookup Home interface
sampleejbHome SampleejbHome = (sampleejbHome)PortableRemoteObject.narrow(context.lookup("sampleejb"), sampleejbHome.class);
// Create the bean and the remote interface
Sampleejb = SampleejbHome.create();
mess = Sampleejb.hello("Middle Tier JSP EJB Client");
// Destroy the Bean Instance
catch(Throwable ex)
ex.printStackTrace();
When I run this code we get following exception:
08/10/15 16:21:35 javax.naming.NameNotFoundException: ejbserverapp/sampleejb not found

What we really want is to have webapp with JSP running on one server and EJB running on another server. Need some help.
Thanks in advance.

Answer 1

This connection string does not look correct to me:
String pURL="opmn:ormi://localhost:12401:OC4J_TEST/";
As you have it, you are specifying the OC4J RMI port to connect to, in conjunction with the ORMI lookup handler.
The correct form for this string should be using the OPMN request port:
String pURL="opmn:ormi://localhost:6003:OC4J_TEST/";
The6003 value comes from the request port that OPMN is using on the target application server instance you need to connect to -- you can observe this port by looking at the $ORACLE_HOME/opmn/conf/opmn.xml file and look for this element:
<port local="6101" remote="6202" request="6003"/>
Use whatever port is specified there in your connect string.
