java.lang.ClassNotFoundException：com.google.gwt.user.client.rpc.RemoteService [英] java.lang.ClassNotFoundException: com.google.gwt.user.client.rpc.RemoteService

问题描述

在Tomcat 6中部署我的war文件时，出现以下异常：

java.lang.ClassNotFoundException：com.google.gwt.user.client.rpc。 RemoteService

所以我尝试着使用webAppCreator来使用最简单的gwt项目：

它是类尝试加载不在gwt-servlet.jar中，但存在于gwt-user.jar中。所有地方都说我不需要gwt-user.jar来部署。这是gwt 2.5.1。帮帮我！！！

使用webAppCreator如下：

webAppCreator com.mytest.TestGwtRpc

然后使用build.xml创建war文件。在Tomcat中部署6.启动并单击发送按钮并获得以下内容：

java.lang.NoClassDefFoundError：com / google / gwt / user / client / rpc / RemoteService

根本原因

java.lang.ClassNotFoundException：com.google.gwt.user.client.rpc .RemoteService

解决方案

RemoteService绝对位于 gwt-servlet.jar of gwt-2.5.1。

因此，请尝试解压缩您的war文件，并验证gwt-servlet.jar位于

  war / WEB-INF / lib / gwt-servlet.jar 
  

我认为，这个罐子可能不在那里？但是，如果是这样，请解压缩gwt-servlet.jar，然后验证该类是否在

  com / google / gwt / user /client/rpc/RemoteService.class 
  

如果它确实存在，那么可能还有其他事情正在进行部署（也许清理tomcat的工作目录，并确保没有其他战争部署可能导致错误，......）

I am getting the following exception when deploying my war file in Tomcat 6

java.lang.ClassNotFoundException: com.google.gwt.user.client.rpc.RemoteService

So I tried to use just the most simplest gwt project by using webAppCreator:

The class it is trying to load is not in gwt-servlet.jar but does exist in gwt-user.jar. All places say I don't need gwt-user.jar to be deployed. This is with gwt 2.5.1. HELP!!!

used webAppCreator as follows:

webAppCreator com.mytest.TestGwtRpc

Then used the build.xml to create the war file. Deployed in Tomcat 6. started up and clicked the send button and get the following:

java.lang.NoClassDefFoundError: com/google/gwt/user/client/rpc/RemoteService

root cause

java.lang.ClassNotFoundException: com.google.gwt.user.client.rpc.RemoteService

解决方案

RemoteService definitely is in gwt-servlet.jar of gwt-2.5.1.

So try unzipping your war file, and verify that gwt-servlet.jar is at

war/WEB-INF/lib/gwt-servlet.jar

I assume, that the jar is probably not there? But if it is, unzip gwt-servlet.jar, and verify that the class is at

com/google/gwt/user/client/rpc/RemoteService.class

If it's actually there, then probably something else is going on with deployment (maybe clean up tomcat's work dir, and make sure that there are no other wars deployed which could cause the error, ...)
