java.rmi.MarshalException [英] java.rmi.MarshalException

问题描述

每当我尝试从客户端调用ejb时，都会收到以下错误：

whenever I try to call my ejb from a client, I get this error :

  java.rmi.MarshalException: Failed to communicate. 

    Problem during     marshalling/unmarshalling; nested exception is: 

    java.io.InvalidClassException: com.afrikbrain.util.message.MessageInfo;

    local     class incompatible:

   stream classdesc serialVersionUID = 2285009932770474121, 

   local class     serialVersionUID = -2900394430145132451 at      

  org.jboss.remoting.transport.socket.SocketClientInvoker.handleException(SocketClientInvoker
.java:122)

为什么会发生？如何解决？

why is it occuring ? and how to solve it ?

推荐答案

本地类和远程类是不同的版本。在解组过程中，接收方不支持发送方的协议版本。确保服务器上的编译类与客户机上编译类的版本是一样的，因此可以将其序列化/反序列化。
我建议您从零开始重新整理项目并重新部署，并重新生成存根。

The local class and the remote class are differente versions. During the unmarshalling process the receiver does not support the protocol version of the sender. Make sure the compiled class on the server is the same version of the compiled class on the client, so can be serialized/deserialized without problems. I suggest you rebuilding from zero all the project and redeploying them, and regenerate the stubs.
