java - 启动 jetty 服务器时出现 NoClassDefFoundError

Question

我正在尝试在 jetty 服务器中托管我的 web 应用程序(spring)。我将我的 war 文件复制到 jetty 服务器中的“webapp”文件夹中。我不是要嵌入 jetty 服务器，而是要在 jetty 内托管应用程序(如 tomcat)。

我没有安装 jetty，我只是下载了 jetty7 zip 并解压以获取服务器。

我需要在 3 台 Linux 机器上进行设置。在一台机器中，服务器启动正常。没有问题。

但在另外两个中，当服务器启动时显示以下错误。

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

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?

Answer 1

正如 Stevie 在评论中指出的那样，问题是一个额外的 Jar 文件进入了 war 。

我从 WEB-INF/lib 中删除了 Jar，在我的例子中是 spring-webmvc-3.1.0.M1.jar 并重新启动了 jetty 。它启动了很好。

这没有引起注意，因为它在编译/构建期间出现(在 eclipse 中订购了 jar)，也没有出现在我部署的第一台机器上。

非常感谢您的帮助。
