一个rmi的入门问题,帮忙看一下

[panwxiong]

我写了一个rmi的程序，如下(jbuilder 9)
//remote.java
package rmi01;
import java.rmi.*;
public interface remote extends java.rmi.Remote{
public String method()throws java.rmi.RemoteException;
}

//app1.java
package rmi01;
import java.rmi.*;
import java.rmi.server.*;

public class app1 extends java.rmi.server.UnicastRemoteObject implements remote{
public app1() throws java.rmi.RemoteException{
super();
}
public String method() throws RemoteException{
return "This is remote method";
}
public void localMethod() throws java.rmi.RemoteException{}

}
//Server.java
package rmi01;
import java.rmi.*;
import java.rmi.server.*;
public class Server {
public static void main(String args[]){
try{
app1 app = new app1();
Naming.rebind("rmi://127.0.0.1:8080/Server",app);
System.out.println("Server created and bound in the registry to rmi");
}
catch(Exception e){
System.out.println("Exception error");
e.printStackTrace();
}
}
}
编译通过，在cmd下运行rmiregistry 8080后运行Server,提示

不知道为什么？请高手看一下，不胜感谢

你的实现RMI接口的类app1在编译过后，有经过rmic再编译过吗？
要将经rmic编译生成的两个.class文件放在rmi01目录下。

good luck :)

[mietian]

在jb中不用经过专门的rmic编译，但你的server类必须在属性中选择一个rmi有关的选项！java2版本只生成stub文件！然后在project属性中添加执行参数，跟那个权限问题有关的，跟.pority文件有关的！这样应该就没问题了！祝好运！

[panwxiong]

问题已经解决，我把环境变量中的classpath删除后运行正常，原来的classpath中有个winrunner的值。再请教mietain，如何在project中添加执行参数？
