Unable to access an EJB deployed in jboss as 7

Question

I have deployed an EJB in Jboss As 7.0.

Following is what the deployment logs says about the JNDI binding of EJB.

19:21:43,269 INFO [org.jboss.as.ejb3.deployment.processors.EjbJndiBindingsDeploymentUnitProcessor] (MSC service thread 1-1) JNDI bindings for session bean named ManageEmployeeBean in deployment unit deployment "EJBTest1.jar" are as follows:

java:global/EJBTest1/ManageEmployeeBean!com.test.ejb.businessimpl.ManageEmployeeBeanRemote java:app/EJBTest1/ManageEmployeeBean!com.test.ejb.businessimpl.ManageEmployeeBeanRemote java:module/ManageEmployeeBean!com.test.ejb.businessimpl.ManageEmployeeBeanRemote java:jboss/exported/EJBTest1/ManageEmployeeBean!com.test.ejb.businessimpl.ManageEmployeeBeanRemote java:global/EJBTest1/ManageEmployeeBean java:app/EJBTest1/ManageEmployeeBean java:module/ManageEmployeeBean

This is how my client class looks like.

package com.test.ejb.test;

import java.util.Hashtable;
import java.util.Properties;

import javax.naming.Context;
import javax.naming.InitialContext;
import javax.naming.NamingException;

import com.test.ejb.bean.Employee;
import com.test.ejb.businessimpl.ManageEmployeeBean;
import com.test.ejb.businessimpl.ManageEmployeeBeanRemote;

public class Client {

    private static InitialContext initialContext;

    public static void main(String[] args){
        try {
            getInitialContext();
            System.out.println("CTX:"+initialContext);
        } catch (NamingException e) {
            e.printStackTrace();
        }

        try {
            System.out.println("Looking up EJB !!");
            ManageEmployeeBeanRemote remote = 
                    (ManageEmployeeBeanRemote)initialContext.lookup("/EJBTest1/ManageEmployeeBean!com.test.ejb.businessimpl.ManageEmployeeBeanRemote");
            System.out.println("setting employee..............");
            Employee employee = new Employee();
            employee.setFirstName("Renjith");
            employee.setLastName("Ravi");

            System.out.println("Adding employee");
            remote.addEmployee(employee);
        } catch (NamingException e) {
            e.printStackTrace();
        }
    }

    public static InitialContext getInitialContext() throws NamingException {
        if (initialContext == null) {
            Properties prop = new Properties();
            prop.put(Context.INITIAL_CONTEXT_FACTORY, "org.jnp.interfaces.NamingContextFactory");
            prop.put(Context.URL_PKG_PREFIXES, "org.jboss.naming:org.jnp.interfaces");
            prop.put(Context.PROVIDER_URL, "remote://localhost:4447");
            prop.put(Context.SECURITY_PRINCIPAL, "renjith");
            prop.put(Context.SECURITY_CREDENTIALS, "user");
            initialContext = new InitialContext(prop);
        }
        return initialContext;
    }


}

Client is not able to find the service when I run it.

Can anyone tell me what am i missing here? I saw lots of threads on similar topic in stackoverflow, but none of them helped me!!

Answer 1

You are attempting to use the EJB Remote client from JBoss AS 5 (or earlier).

You need to use the JBoss AS 7 EJB Remote client and configure it as per the documentation at AS7 JNDI Reference under the Remote JNDI heading.
