RemoteException java.rmi.UnmarshalException：错误解组返回 [英] RemoteException java.rmi.UnmarshalException: error unmarshalling return

问题描述

我正在运行程序这里在差异物理机器上的2个JVM上。我收到错误

  RemoteException 
 java.rmi.UnmarshalException：error unmarshalling return;嵌套异常是：
 java.lang.ClassNotFoundException：CalculatorImpl_Stub（没有安全管理器：禁用RMI类加载器）
  

我甚至尝试在同一台机器上运行它（未更改的程序）并且它可以工作但它在diff机器上不起作用。有人可以帮助我吗？

@ beny23-谢谢，但我仍然会遇到这个错误：

  RemoteException 
 java.rmi.UnmarshalException：error unmarshalling return;嵌套异常是：
 java.lang.ClassNotFoundException：CalculatorImpl_Stub 
  

客户端如何拥有CalculatorImpl_stub的副本？

解决方案

听起来你没有使用安全管理器：

您是否有政策文件（ my.policy ）：

  grant {
 permission java.security.AllPermission; 
}; 
  

并使用

<$ p $运行程序p> java -Djava.security.manager -Djava.security.policy = / some / path / my.policy MyClass


I'm running the program here on 2 JVMs on diff physical machines. I get the error

RemoteException
java.rmi.UnmarshalException: error unmarshalling return; nested exception is: 
    java.lang.ClassNotFoundException: CalculatorImpl_Stub (no security manager: RMI class loader disabled)

I've even tried running it on the same machine(unchanged program) and it works but it doesnt work on diff machines. Can someone pls help me out?

@beny23- Thanks but I still end up with this error:

RemoteException
java.rmi.UnmarshalException: error unmarshalling return; nested exception is: 
java.lang.ClassNotFoundException: CalculatorImpl_Stub

How can the client side have a copy of CalculatorImpl_stub?

解决方案

It sounds like your not using a security manager:

Have you got a policy file (my.policy):

grant {
  permission java.security.AllPermission;
};

and run your program using

java -Djava.security.manager -Djava.security.policy=/some/path/my.policy MyClass
