无法访问部署在jboss as 7中的EJB

Question

我在Jboss 7.0中部署了一个EJB。

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;
    }


}

当我运行该服务时，客户端无法找到该服务。

谁能告诉我我在这里遗漏了什么？我在stackoverflow中看到了很多类似主题的线程，但没有一个对我有帮助！！

您试图使用JBoss AS 5（或更早版本）中的EJB远程客户端。

您需要使用JBoss AS 7 EJB远程客户机，并根据AS7 JNDI参考中Remote JNDI标题下的文档对其进行配置。
