我按照书上的例子,但我遇到了很多错误.
我跑了rmiregistry.
然后我完成了.
java MyremoteImpl
这给了我以下错误：

这是我的MyRemoteImpl代码：
import java.rmi.Naming;
import java.rmi.remoteexception;
import java.rmi.server.UnicastRemoteObject;
public class MyRemoteImpl extends UnicastRemoteObject implements MyRemote {
@Override
public String sayHello(){
return "server says,'hey'";
}
public MyRemoteImpl() throws remoteexception{
}
public static void main (String [] args){
try{
MyRemote service = new MyRemoteImpl();
Naming.rebind("RemoteHello",service);
} catch (Exception ex) { ex.printstacktrace();
}
}
}
MyRemoteClient代码：
import java.rmi.*;
public class MyRemoteClient {
public static void main(String [] args){
new MyRemoteClient().go();
}
public void go(){
try {
MyRemote service = (MyRemote) Naming.lookup("rmi://127.0.0.1/RemoteHello");
String s = service.sayHello();
System.out.println(s);
}catch(Exception ex){
ex.printstacktrace();
}
}
}
我的远程代码：
import java.rmi.*;
public interface MyRemote extends Remote {
public String sayHello() throws remoteexception;
}
最佳答案
