RMI问题：java.rmi.UnmarshalException: Error unmarshaling return header

[joy_wind]

我在编写一个RMI服务端,代码如下:
try {
Naming.rebind ("sys", new SysImpl ());
} catch (Exception e) {
System.exit(1);
}

在Win2000上运行正常,放到Linux上后出现以下异常:

java.rmi.UnmarshalException: Error unmarshaling return header; nested exception
is:
java.net.SocketException: Connection reset

请问是怎么回事啊??

代码能多贴些吗？

加一个“/”，改成下面的格式试一下：
try{
Display obj = new Display();
Naming.rebind("/Display", obj);
}catch(Exception e)

也许和路径有关系吧
