Question

我正在尝试在应用程序服务器之外构建EJB客户端以访问WebLogic Server中的EJB，但是当我运行客户端应用程序时，我遇到了通信故障。尝试谷歌这个问题，但有关此问题的细节很少，大多数建议是检查WLS是否已启动并运行但似乎我的问题不同，因为即使我的应用程序服务器正在运行，我仍然遇到通信问题。< / p>

我希望你能帮我。请参阅下面我在运行EJB应用程序时遇到的异常以及我的Java代码。

远程接口：

package com.jake.mine;

import javax.ejb.Remote;

@Remote
public interface CalculatorRemote {

    int add(int x, int y);
}

实施班级：

package com.jake.bagain;

import javax.ejb.Stateless;

@Stateless(mappedName="ejb/calc")
public class CalculatorRemoteImpl implements CalculatorRemote {

    public int add(int x, int y) {
        return x + y;
    }
}

测试类：

package com.jake.mine;

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

public class TestEJB {

   public static void main(String[] args)  {
        try {
            Hashtable ht = new Hashtable();
            ht.put(Context.INITIAL_CONTEXT_FACTORY, 
"weblogic.jndi.WLInitialContextFactory");
            ht.put(Context.PROVIDER_URL, "http://localhost:7001");

            Context context = new InitialContext(ht);
            CalculatorRemote remote = 
(CalculatorRemote)context.lookup("ejb.calc#com.jake.mine.CalculatorRemote");
            System.out.println(remote.add(100, 100));
        } catch (Exception e) {
            e.printStackTrace();
        }

    }
}
