Exception while accessing deployed session bean

Question

Hi,
I am new to IPlanet AS 6.0 . I wrote a simple stateless session bean in Forte EE v 3.0 environment. The compilation and deployment went fine. When I try to use my bean through a client program using IIOP then it throws the following exception in kjs:
javax.naming.NameNotFoundException: EjbContext: exception on getHome(), com.netscape.server.eb.UncheckedException: unchecked exception thrown by impl com.kivasoft.eb.boot.EBBootstrapImpl@71dc3d; nested exception is:

My client program is:
import java.util.*;
import javax.naming.Context;
import javax.naming.InitialContext;
import javax.rmi.PortableRemoteObject;
public class MybeanClient {
public static void main(String[] args) {
try {
Properties env = new Properties();
env.put("java.naming.factory.initial","com.sun.jndi.cosnaming.CNCtxFactory");
env.put("java.naming.provider.url", "iiop://localhost:9010");
Context initial = new InitialContext(env);
Object objref = initial.lookup("ejb/Mybean");
MybeanHome home =(MybeanHome)PortableRemoteObject.narrow(objref,My beanHome.class);
Mybean bean = home.create();
String result = bean.test();
System.out.println(result);
} catch (Exception ex) {
System.err.println("Caught an unexpected exception!");
ex.printStackTrace();
The j2eeguide.converter sample bundled with IPlanet works fine with the above code.
The only difference is that the converter sample was deployed by the IAS deployment tool.
Mybean was deployed by the Forte.
What is the problem?
Any help would be highly appreciated.

Answer 1

1. Check that iiop is enabled in ias-ejb-jar.xml
2. Check your naming in the xml files
3. Check what has been deployed (filesystem & kregedit)
4. Try it with the full qualified name ejb/'ejbfilename'/<ejb-name>
