我想将我的 GWT 项目部署到码头服务器，但如果我将 war 文件放入 webapps 文件夹，我会得到“HTTP 错误：503 - 服务不可用”。我检查了日志文件，它显示了这个异常：

我认为这是由我必须用于“GWT EVENT SERVICE”的外部 servlet 引起的，这来自我的 web.xml：
<servlet>
<servlet-name>eventServiceImpl</servlet-name>
<servlet-class>de.novanic.eventservice.service.EventServiceImpl</servlet-class>
</servlet>
<servlet-mapping>
<servlet-name>eventServiceImpl</servlet-name>
<url-pattern>/verboteneinsel/gwteventservice</url-pattern>
</servlet-mapping>
如果我通过 GWT 以开发模式在本地运行我的项目，一切正常......
