我已经下载了最新的Jetty 8 Hightide，但是无法使WebSockets正常工作.我解压缩发行版，将.war文件放到webapps文件夹中，然后开始:

I've downloaded the latest Jetty 8 Hightide, but cannot get WebSockets to work. I unzip the distribution, put my .war file in the webapps folder and start:

java.lang.NoClassDefFoundError: org/eclipse/jetty/websocket/WebSocketServlet

我已经验证JETTY_HOME/lib文件夹包含jetty-websocket.jar并且它包含WebSocketServlet类文件.

I've verified that the JETTY_HOME/lib folder contains the jetty-websocket.jar and it contains the WebSocketServlet class file.

我在里程碑发布之前就已经运行过了.

I've had this running before with the milestone releases.

推荐答案

由于某些原因，默认情况下似乎不再提供Web套接字，因此上下文XML文件中需要以下代码:

For some reason, it appears that web sockets are no longer available by default, so the following code is needed in the context XML file:

<Set name="extraClasspath"><SystemProperty name="jetty.home" default="."/>/lib/jetty-websocket-<version>.jar</Set>
