本文介绍了启动码头服务器时出现NoClassDefFoundError的处理方法，对大家解决问题具有一定的参考价值，需要的朋友们下面随着小编来一起学习吧！

问题描述

我正在尝试将我的webapp(春季)托管在码头服务器中.我将战争文件复制到了码头服务器的"webapp"文件夹中.我不是要嵌入码头服务器，而是要在码头内托管应用程序(例如tomcat).

I am trying to host my webapp (spring) in jetty server. I copied my war file to the 'webapp' folder in the jetty server. I am not trying to embed the jetty server, but trying to host the app within the jetty (like tomcat).

我安装了jetty，我刚刚下载了jetty7 zip并解压缩以获取服务器.

I dint install jetty, I just downloaded the jetty7 zip and extracted to get the server.

我需要在3台Linux机器上进行设置.在一台机器上，服务器可以正常启动.没有问题.

I need to set this up in 3 linux machines. In One machine the server is starting up just fine.No issues.

但是在另外两个中，当服务器启动时，它显示以下错误.

But in the other two, when the Server is starting up it is showing the following error.

请注意，默认端口已更改为9080.

Kindly note that the default port have been changed to 9080.

我暗示这可能是一些配置更改，因为它在一台机器上运行良好. 您能帮我指导解决此问题吗?

I have an inkling that it might be some configuration change, as it is working fine in one machine. Could you please help me with a guidance to solve this?

推荐答案

正如Stevie在评论中指出的那样， 问题是进入战争的另一个Jar文件.

As Stevie pointed out in the comments, the issue was an additional Jar file which got into the war.

我从WEB-INF/lib中移除了Jar(在我的情况下为spring-webmvc-3.1.0.M1.jar)并重新启动了码头.它很好地启动了.

I removed the Jar, in my case spring-webmvc-3.1.0.M1.jar, from WEB-INF/lib and restarted jetty.It started up fine.

由于它在编译/构建期间出现(没有按日食订购的jar)，也没有出现，也没有出现在我部署的第一台机器中.

This went unnoticed as it dint show up during compile/build time (got the jar ordered in eclipse), nor did it showed up in the first machine i deployed.

非常感谢您的帮助.
