CMB accessing remote OC4J problem

Question

I create a CMBean from table, before using this CMB accesses remote OC4J,all are right (deploy is ok,testing in embedded oc4j is ok,even using session bean accessing remote OC4J is ok)
the client code is:
try
Hashtable env = new Hashtable();
env.put(Context.INITIAL_CONTEXT_FACTORY, "com.evermind.server.rmi.RMIInitialContextFactory");
env.put(Context.SECURITY_PRINCIPAL, "admin");
env.put(Context.SECURITY_CREDENTIALS, "welcome");
env.put(Context.PROVIDER_URL, "ormi://cly:23791/emp");
Context ctx = new InitialContext(env);
EmpHome empHome = (EmpHome)ctx.lookup("Emp");
Emp emp;
The console displays:
javax.naming.NamingException: Lookup error: java.io.IOException: Class Not Found: com.evermind.server.ejb.DummyRemote; nested exception is:
     java.io.IOException: Class Not Found: com.evermind.server.ejb.DummyRemote
     java.lang.Object com.evermind.server.rmi.RMIContext.lookup(java.lang.String)
     java.lang.Object javax.naming.InitialContext.lookup(java.lang.String)
     void Samplepk.EmpClient2.main(java.lang.String[])
Process exited with exit code 0.
How can solve this problem

Hi Chen,
I assume you mean CMP entity bean (when you talk about a "CMB").
However, what I cannot deduce is, what OC4J are you referring to:
1. OC4J in JDeveloper
2. OC4J stand-alone
3. OC4J in 9iAS
[and which version(s) of the above]
I'm only guessing, but perhaps you have developed your (CMP entity) bean in JDeveloper, and are trying to deploy it in either OC4J stand-alone or 9iAS, correct?
If this is the case, you may have a compatibility mismatch between the various products (JDeveloper, OC4J, 9iAS).
Personally, I only use OC4J stand-alone. I don't use JDeveloper, and I use the tools that come with OC4J stand-alone to deploy my EJBs.
Hope this helps.
Good Luck,
Avi.
