对于接口(interface)

enter code here
package com.iqbal.interfaces;

import javax.ejb.Remote;

@Remote
public interface ISessionFacade1Local 
{
    public double generatedRandomNumber(int number);
}

对于 session Bean

enter code here

package com.iqbal.ejb;

import javax.ejb.Stateless;

import com.iqbal.interfaces.ISessionFacade1Local;

@Stateless(name="SessionFacade1", mappedName="SessionFacade1")
public class SessionFacade1 implements ISessionFacade1Local
{

    @Override
    public double generatedRandomNumber(int number) 
    {
        // TODO Auto-generated method stub
        return Math.random();
    }

}

对于客户

enter code here
package com.iqbal.client;
import java.util.Properties;

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

import com.iqbal.interfaces.ISessionFacade1Local;


public class BeanClient 
{
    public static void main(String[] args)
    {
          Properties props = new Properties();

          props.setProperty("java.naming.factory.initial",
                            "com.sun.enterprise.naming.SerialInitContextFactory");

          props.setProperty("java.naming.factory.url.pkgs",
                            "com.sun.enterprise.naming");

          props.setProperty("java.naming.factory.state",
                            "com.sun.corba.ee.impl.presentation.rmi.JNDIStateFactoryImpl");


          // optional.  Defaults to localhost.  Only needed if web server is running
          // on a different host than the appserver   
          props.setProperty("org.omg.CORBA.ORBInitialHost", "localhost");

          // optional.  Defaults to 3700.  Only needed if target orb port is not 3700.
          props.setProperty("org.omg.CORBA.ORBInitialPort", "8080");

          try 
          {
            InitialContext ic = new InitialContext(props);
            ISessionFacade1Local local = (ISessionFacade1Local)ic.lookup("SessionFacade1#com.iqbal.interfaces.ISessionFacade1Local");

            System.out.println("Random Number is== "+local.generatedRandomNumber(200));
          } 
          catch (NamingException e) {
            // TODO Auto-generated catch block
            e.printStackTrace();
        }
    }
}

我已经从构建路径将 SessionBean 项目添加到 SessionBeanClient，并添加了 appserv-rt.jar 和 gf-client.jar 以及 glassfish 服务器库。但是..上面的错误仍然出现。任何人都可以帮忙，拜托...？

Answer 1

我已经得到答案了，只需将端口 8080 更改为 3700。为什么？因为 8080 是本地的，而且因为我在界面中设置了 @Remote，所以我必须使用 3700。尝试一下，如果有什么问题，告诉我。
