Java RmiClient服务器错误

我在下面得到了这个错误：

RmiClient异常：java.rmi.ServerError:服务器中发生错误 线嵌套异常为：java.lang.AbstractMethodError

如果每次按下按钮，将与同一系统上的服务器通信，则会出现如下错误：

RmiClient exception: java.rmi.ServerError: Error occurred in server thread; nest
ed exception is:
        java.lang.AbstractMethodError: ServerGUI.getMessage(Ljava/lang/String;J)
Ljava/lang/String;
java.rmi.ServerError: Error occurred in server thread; nested exception is:

仅仅通过查看堆栈跟踪就很难判断。但请确保使用Thread扩展服务器类，并在客户端类中实现以下内容

EventQueue.invokeLater(new Runnable(){
   public void run(){
    //////// do something with the client window frame
   }
});

您在没有重新编译或重新部署的情况下更改了某些内容。可能是远程方法的签名。进行干净的构建和重新部署。

这方面很难提供帮助，因为您没有包含任何代码，甚至没有对您尝试执行的操作进行任何描述。我可以告诉您，调用的方法没有实现（抽象），但这是我在没有更多信息的情况下所能得到的。而且，看起来您发布了相同的巨大堆栈跟踪twice@Floegipoky一个抽象方法的错误没有什么神秘之处。请参阅Javadoc。感谢您的回答，但我需要一些代码实现或一些网站，从那里我可以获得一些示例。由于我是RMI的新手，我想了解更多。你试过使用谷歌吗？你知道，你可以在谷歌上输入两个单词，比如“rmi示例”。这些都是无关紧要的。
