本文介绍了将GWT-RPC-Applicaton部署到JBoss AS 7.1.1时发生ClassNotFoundException的处理方法，对大家解决问题具有一定的参考价值，需要的朋友们下面随着小编来一起学习吧！

问题描述

我有一个基于Maven的GWT应用程序.

I have a maven base GWT-Application.

当我进行编译，构建并将其通过Maven部署到JBoss AS 7.1.1时，我为我的GWT-RPC-Service得到了ClassNotFoundException.在加入之前，我已经部署好了并且可以显示GWT小部件，所以GWT罐子应该在那儿...

When i compile, build and deploy it to JBoss AS 7.1.1 over Maven I get an ClassNotFoundException for my GWT-RPC-Service. Before I Included that i deployed and i could display the GWT-Widgets, so the GWT-Jars should be there...

我的Maven依赖关系如下:

My Maven-Dependencies look like this:

<dependency>
  <groupId>com.google.gwt</groupId>
  <artifactId>gwt-dev</artifactId>
  <version>2.5.0</version>
  <scope>compile</scope>
</dependency>
<dependency>
  <groupId>com.google.gwt</groupId>
  <artifactId>gwt-user</artifactId>
  <version>2.5.0</version>
  <scope>compile</scope>
</dependency>
<dependency>
  <groupId>com.google.gwt</groupId>
  <artifactId>gwt-servlet</artifactId>
  <version>2.5.0</version>
  <scope>compile</scope>
</dependency>

我的EAR看起来像这样:

有人知道怎么了吗?

推荐答案

感谢您的输入. 我现在找出问题所在.

thanks for your Input. I now figures out the Problem.

是一个愚蠢的错误.在maven配置中，我设置了client-Package中的所有类都不应该包含在包装中，因为它们都已编译为JS.所以这包括我的服务接口... 我将其移至共享的新Package中，并将其包含在gwt.xml中.

Was a stupid Mistake. In the maven config I set that all Classes in the client-Package should not be included in the packaging, since they are compiled to JS. So that included my Service-Interface... I moved it to a new Package shared and included that in the gwt.xml.

还将gwt-user和gwt-dev更改为提供的maven范围，并将gwt-servlet更改为运行时.

Also changed gwt-user and gwt-dev to the maven scope provided and gwt-servlet to runtime.

配置成功后，:-)
