HOW TO: Deploy an Application Client in WAS

[Rahul Mahindrakar]

Hi,
After having deployed the Hello.jar which is available in the deployableEJB's folder sucessfully i am trying to access the Bean through a client. Following is the code for the application

import java.io.*;
import com.ibm.ejb.cb.samples.hello.tier2.HelloHome;
import com.ibm.ejb.cb.samples.hello.tier2.Hello;
import java.util.*;
import javax.naming.*;
public class HelloHomeClient{
    public static void main(String[] args){
        try{
            InitialContext ctx = null;
            Properties env = System.getProperties();
            env.put(Context.PROVIDER_URL, "iiop://localhost:900");                                    
            env.put(Context.INITIAL_CONTEXT_FACTORY, "com.ibm.ejs.ns.jndi.CNInitialContextFactory");
            env.put("org.omg.CORBA.ORBClass", "com.ibm.CORBA.iiop.ORB");
            System.out.println("upto here");
            ctx = new InitialContext(env);
            System.out.println("upto here1");
            Object homeObject = ctx.lookup("HelloHome");
            System.out.println("upto here");
            
            HelloHome incHome = (HelloHome)javax.rmi.PortableRemoteObject.narrow(homeObject, HelloHome.class);
            Hello incHello=incHome.create();
            String s=incHello.getMessage();
            System.out.println("My frist servlet to access EJB "+s);
         }catch ( Exception e ){
            System.out.println(e);
         }
    }
}

However i get the following error.
upto here
javax.naming.NoInitialContextException: Cannot instantiate class: com.ibm.ejs.ns
.jndi.CNInitialContextFactory [Root exception is java.lang.ClassNotFoundExceptio
n: com.ibm.ejs.ns.jndi.CNInitialContextFactory]
Am i missing something. If so what is it. Also note the braces in in the last line above "CNInitialContextFactory]"

Hello Mahindrakar,
Comparing your error with the client call of EJB deployed in OAS, I suggest, you check up if all the requied JARs are available for client call.I had got this error while client call, since I missed out Oracle deployment utility generated files as well as aurora.jar!!
Let us know, if you make a breakthrough with this.

I know there is some jar file i am missing out. But which one is it. At present i do not have any jars in my class path. Which ones do i put.
For example in J2EE the deployer tool specifically creates a Client.jar file which i have to have in my classpath before i run my application. Is there something of this sort in WAS. If so what is it and how do i generate it

Hi Rahul,
Try putting the following line in the provider url syntax
env.put(Context.PROVIDER_URL,"iiop:///localhost:9000");

Note that theere are 3 /'s after iiop and the default port used for iiop comm is 9000, this should run it,
Cheers,
Daman

One more thing, u need to have ujc.jar in your classpath.
