Access remote ejb in oc4j

Question

I use oc4j in jdeveloper 10G in access a remote EJB using
sample java client both of EJB and java client on MY COMPUTER
AS SERVER I THINK I HAVE PROBLEM IN SETTING CLASS PATHS
I HAVE DOWNLOAD J2EE SDK VER 1.3.1 AND I ASSIGN MY CLASSPATHS
AS FOLLOWS:
C:\java_course1\jdbc\lib\classes12.jar;C:\java_course1\jdbc\lib\nls_charset12.jar; c:\java_course1\j2ee\home\lib;c:\java_course1\lib\ ; C:\J2Sdkee1.3.1\lib\j2ee.jar
java_course1 is folder of jdeveloper
j2Sdkee.1.3.1 is J2EE SDK VER 1.3.1
the code i have written in java client
env.put(Context.INITIAL_CONTEXT_FACTORY,"RMIInitialContextFactory");
env.put(Context.SECURITY_PRINCIPAL, "admin");
env.put(Context.SECURITY_CREDENTIALS, "welcome");
env.put(Context.PROVIDER_URL, "ormi://localhost:23893/current-workspace-app");
Context context = new javax.naming.InitialContext(env);
EmpHome empHome = (EmpHome)PortableRemoteObject.narrow(context.lookup("EmpHome"), EmpHome.class);
I get the following error message
javax.naming.NoInitialContextException: Cannot instantiate class: RMIInitialContextFactory [Root exception is java.lang.ClassNotFoundException: RMIInitialContextFactory]
Is Someting is missed in class pathes or should i copy j2ee.jar file from
C:\J2Sdkee1.3.1\lib\j2ee.jar to oc4j folder

in class paths or environment variables
