Java GWT-RemoteEventServiceServlet-编译错误

我刚刚试着做了这个，但是我得到了编译错误

我的

gwt.xml

非常标准：

<inherits name="com.google.gwt.user.User"/>
    <inherits name="com.google.gwt.user.theme.standard.Standard"/>
    <inherits name='de.novanic.eventservice.GWTEventService' /> 

    <entry-point class="com.mycompany.project.client.ImageViewer"/>

---

代码的其余部分与示例完全相同。我真的不知道是什么导致了错误。

我需要查看ImageViewer的源代码。看起来您正试图在客户端上使用服务器库。@Travis感谢您的注释；我想你是对的，因为我已经将上面提到的对象替换到了客户机文件夹中，这很好；但由于某种原因，我无法运行代码；我收到这个错误[error]客户端错误：注册域的客户端时出错！com.google.gwt.user.client.rpc.StatusCodeException:404是代码问题还是某些配置？
