Java 启动jetty服务器时发生NoClassDefFoundError

我正在尝试在jetty server中托管我的webapp（spring）。我将war文件复制到jetty服务器的“webapp”文件夹中。我不是想嵌入jetty服务器，而是想在jetty中托管应用程序（比如tomcat）

我并没有安装jetty，我只是下载了jetty7的zip文件并解压缩了服务器

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

但在另外两种情况下，当服务器启动时，会显示以下错误

正如Stevie在评论中指出的， 问题是另一个卷入战争的Jar文件

我从

WEB-INF/lib

中移除了Jar，在我的例子中是

spring-webmvc-3.1.0.M1.Jar

，并重新启动了jetty。它启动得很好

这没有被注意到，因为它在编译/构建时（在eclipse中订购了jar）没有出现，在我部署的第一台机器中也没有出现

---

非常感谢您的帮助。

您可以更改项目配置，就像我在本页中使用maven一样。

然后，当您在EclipseET中使用“更新maven项目”时，它将下载

---

complier的jedis.jar和其他关系文件。它将在jetty中工作以解决问题。

如果您直接使用jetty作为Eclipse J2EE集成服务器， 有时，它找不到一些库（我不明白为什么只有少数库找不到一些库），并抛出此类异常（NoClassDefFound）

• 因此，您必须输入项目源（WEB-INF目录）：您的JAR

• 重新启动服务器

• 它将JAR放入运行时WEB-INF： Data\workspace.metadata.plugins\org.eclipse.wst.server.core\tmpX\MyApp\WEB-INF\lib

• 它是有效的

你是如何发动战争的？类路径中似乎缺少org.springframework.web.context.support.DefaultWebEnvironment。。。可能是（错误地）在正在工作的机器上的Jetty类路径上？spring支持jar真的在战争中吗？我不希望Jetty在你的代码中寻找这个类，因为有些东西需要这个类，这就是为什么java试图加载它，但找不到它。你使用的spring的确切版本是什么？DefaultWebEnvironment似乎只存在于3.1.0的预发行版本中（似乎它没有进入发行版）。我建议您至少更新到3.1.x的发行版，或者更好地更新到当前的3.2.2。。。也不要在Jetty的lib目录中放置任何jar！（如果你是这个意思的话）@user2315838这正是重点。您在内部使用的其他类需要它，但它丢失了，所以您得到了ClassNotFound。也许可以找到其他哪个类正在使用它。@user2315838我不知道。你最好的办法是找出哪个类使用了

DefaultWebEnvironment

（查看一些javadoc）并找出为什么它会使用它作为默认值，也许你可以将它设置为其他值。欢迎使用StackOverflow！虽然这可能提供了问题的答案，但您应该始终总结链接的内容，因为它们可能在将来不可用。非常感谢。我有这个问题java.lang.NoClassDefFoundError:org/mortbay/jetty/Handler已经尝试了org.mortbay.jetty的所有maven，但是找不到，打开.jar并包含该路径 Active Options: [Server, client, ext, jmx, jsp, resources, websocket] Version Information on 25 entries in the classpath.
