Eclipse jetty 插件——找不到类 websocketfactory

Question

我有一个网络应用，在 WEB-INF/lib 下有以下库

servlet-api-3.1.jar
websocket-api-9.2.5.v20141112.jar
websocket-servlet-9.2.5.v20141112.jar

当我使用

启动应用程序时

eclipse-jetty-integration plugin 
(  Eclipse Jetty Feature    3.8.0   net.sourceforge.eclipsejetty.feature.feature.group  Christian Köberl)

后端显示没有错误：

当我打开 index.html 时（使用 var ws = new WebSocket('ws://localhost:8080/test/websock')） 后端显示错误：

我在 windowsxp 和 mac osx 下使用 eclipse luna 和 jetty 9.2.5 出现上述错误

但是我有 NO 使用 eclipse luna 和 jetty 9.2.5 的 opensuse 错误

也没有我在 suse 企业服务器下部署 web 时是否有错误，使用 jetty 9.2.5 作为战争文件。

有人知道怎么回事吗？

ps：我查看了线程（java.lang.ClassNotFoundException: org.eclipse.jetty.websocket.server.WebSocketServerFactory）。作者说的是OSGi环境，是不是有问题？

Answer 1

没关系，我想通了。

只需勾选 jetty 插件中的全局复选框。

同样将 common 和 server jar 放在 buildpath 中。
