Run time error while running Session Bean sample

Question

Hi,
I am new to EJB. When I try to run one sample session bean, I am getting following exeception.
javax.naming.NoInitialContextException: Need to specify class name in environment or system property, or as an applet parameter, or in an application resource file: java.naming.factory.initial
     at javax.naming.spi.NamingManager.getInitialContext(NamingManager.java:657)
     at javax.naming.InitialContext.getDefaultInitCtx(InitialContext.java:255)
     at javax.naming.InitialContext.getURLOrDefaultInitCtx(InitialContext.java:292)
     at javax.naming.InitialContext.lookup(InitialContext.java:359)
     at RunEJB.main(RunEJB.java:31)
Exception in thread "main"
This exception is thrown by client project. naming.jar file is already include in the class for Client project as well.
I am testing this sample on WSAD.
The code on the client is as follows.
          Context initial = new InitialContext();
          Context myEnv = (Context)initial.lookup("java:comp/env");
          Object objref = myEnv.lookup("ejb/MyTestBeanHome");
          MyTestBeanHome home =
            (MyTestBeanHome) PortableRemoteObject.narrow(objref, MyTestBeanHome.class);
          MyTestBean firstBean = home.create(); 
          firstBean.testMessage();
          firstBean.remove();

Hi Vikas,
The fact that this client is coded to use java:comp/env means it's a J2EE Application Client component. Application Clients are full-fledged J2EE components that run within an Application Client container. You'll need to consult the documentation for your J2EE implementation to see how to invoke its Application Client container.
