我有两个项目，第一个是Ejb3项目，名称是SessionBean，而Java项目是SessionBeanClient。对于IDE，我使用Eclipse Indigo。我已经完成了代码，当我编译时出现错误。这是错误；

对于界面
enter code here
package com.iqbal.interfaces;
import javax.ejb.Remote;
@Remote
public interface ISessionFacade1Local
{
public double generatedRandomNumber(int number);
}
对于会话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和glassfish服务器库。但是..上面的错误仍然会出来。任何人都可以帮忙，请...？
最佳答案
我已经得到了答案，只是将端口8080更改为3700。为什么？，因为8080用于本地，并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，请告诉我。
