无法访问部署在 jboss 中的 EJB 为 7

Question

我在 Jboss As 7.0 中部署了一个 EJB。

以下是部署日志中有关 EJB 的 JNDI 绑定的内容。

19:21:43,269 信息 [org.jboss.as.ejb3.deployment.processors.EjbJndiBindingsDeploymentUnitProcessor] （MSC 服务线程 1-1）命名为会话 bean 的 JNDI 绑定 部署单元部署“EJBTest1.jar”中的ManageEmployeeBean 为 如下：

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

这就是我的客户端类的样子。

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;
    }


}

运行时客户端找不到服务。

谁能告诉我我在这里缺少什么？ 我在stackoverflow中看到很多类似主题的主题，但没有一个对我有帮助！

您正在尝试使用 JBoss AS 5（或更早版本）的 EJB Remote 客户端。

您需要使用 JBoss AS 7 EJB 远程客户端并按照 AS7 JNDI Reference 的文档在 Remote JNDI 标题下进行配置。
