Java RMI客户端和服务器分离的机器

Question

I want to edit the RMI hello world example to work with client and server on different machines, but i'm stuck with the unmarshalling return error.

If i run client and server in the same project on Netbeans they work fine but when i split them i edited the try statement on the client side to be:

try {
    Registry registry = LocateRegistry.getRegistry("localhost");
    String[] c = registry.list();
    System.out.println(c[0].toString());
    Remote lookup = Naming.lookup("HelloServer");                                             
} catch (Exception e) {
    System.out.println("HelloClient exception: " + e.getMessage());
}

without Remote lookup = Naming.lookup("HelloServer"); , the print command gives "HelloServer" which is correct, but when i create the remote object I'm getting this error:

HelloClient exception: error unmarshalling return; nested exception is: 
java.lang.ClassNotFoundException: rmimain.Hello

I've tested the policy and it's working fine, any help would be much appreciated.

您的客户端的CLASSPATH上没有rmimain.Hello类。
