Getting NameNotFoundException while running client program of EJB

I am new to EJB.

I am trying to learn to develop a stateless bean. I created the jar file and deployed it on Weblogic server and then i executed the client code. I have already set the classpath for api.jar and weblogic.jar. But on running client code i am getting following error:

C:\Users\Asad\Desktop\EJB>java EjbClient1
Exception in thread "main" javax.naming.NameNotFoundException: Unable to resolve 'myAdder#Adder'. Resolved '' [Root exception is javax.naming.NameNotFoundException: Unable to resolve 'myAdder#Adder'. Resolved '']; remaining name 'myAdder#Adder'

Caused by: javax.naming.NameNotFoundException: Unable to resolve 'myAdder#Adder'. Resolved ''

Following is the code.

Client EjbClient1.java:

import javax.naming.*;
import java.util.*;
import javax.naming.Context;  
import javax.naming.InitialContext;  

public class EjbClient1 {
    public static void main(String s[])throws Exception {
        Properties parm=new Properties();
        parm.setProperty("java.naming.factory.initial","weblogic.jndi.WLInitialContextFactory");
        parm.setProperty("java.naming.provider.url","t3://localhost:7001");
        parm.setProperty("java.naming.security.principal","weblogic");
        parm.setProperty("java.naming.security.credentials","asad9711");
        // parm.setProperty("java.naming.security.credentials","weblogic12");

        InitialContext ctx=new InitialContext(parm);
        Adder stub=(Adder)ctx.lookup("myAdder#Adder");

        int c=stub.add(10,20);
        System.out.println(c);

    }
}

Bean class AdderBean.java:

import javax.annotation.PostConstruct;
import javax.annotation.PreDestroy;
import javax.ejb.Stateless;

@Stateless(mappedName="myAdder")
class AdderBean implements Adder {
    @PostConstruct  
    public void init()
    {
        System.out.println("post create");

    }
    @PreDestroy
    public void destroy()
    {
        System.out.println("destroy");
    }
    public int add(int x,int y)
    {
        return x+y;
    }
}

Remote Interface Adder.java:

import javax.ejb.Remote;

@Remote
public interface Adder
{
     int add(int x,int y);
}

Solution

Your code works for me after changing few things.

I changed your session bean's access modifier to public.

Check your jar file contains the class files. It must contain your Interface and SessionBean.

With Command line

1)Compile the project

Project_DIR>javac -d bin -sourcepath src -cp lib\.m2\repo
sitory\javax\javaee-api\6.0\javaee-api-6.0.jar;C:\Oracle\Middleware\wlserver_10.
3\server\lib\weblogic.jar src\main\java\Adder.java src\main\java\AdderBean.java
src\main\java\EjbClient1.java

2)Build jar

Project_DIR\bin>jar cf myejbapp.jar Adder.class AdderBean
.class EjbClient1.class

3)Deploy the myejbapp.jar to weblogic and run the EJBClient1
