Jetty服务器上的GWT部署：java.lang.IllegalStateException:没有这样的servlet:eventServiceImpl

我想将我的GWT项目部署到jetty服务器上，但是如果我将war文件放入webapps文件夹中，就会得到HTTP错误：503-服务不可用。我检查了日志文件，它显示了此异常：

我假设这是由我必须用于GWT事件服务的外部servlet引起的 这是my web.xml中的内容：

<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项目，一切正常…

您的WEB-INF/lib中是否有GWT eventservice JAR？@ThomasBroyer是的。它是。它也在构建路径中，但它被称为gwteventservice-1.2.1。这是一个问题吗？顺便说一句：我正试图在jetty 9上运行它
