技术标签:

【中文标题】APACHE TOMCAT 服务器未启动【英文标题】：APACHE TOMCAT SERVER NOT STARTING 【发布时间】：2018-08-26 05:59:47 【问题描述】：

以前它显示端口号错误。然后我更改了端口号，但过了一段时间它为启动服务器提供了一个新的例外。我从 ECLIPSE 中多次附加和删除服务器，但问题没有解决。

我还重新安装了 ECLIPSE，但例外仍然相同。

控制台上的错误是：

【问题讨论】：

发布错误截图请先修复您的 CAPS LOCK！请阅读Under what circumstances may I add “urgent” or other similar phrases to my question, in order to obtain faster answers? - 总结是这不是解决志愿者的理想方式，并且可能会适得其反。请不要将此添加到您的问题中。 Where to find javax.websocket .jars for use in project的可能重复 Tomcat throwing javax.websocket.DeploymentException 的可能重复项，也可以通过简单的 Google 搜索发现。 【参考方案1】：

检查您的堆栈跟踪，因为这暗示了您面临的问题。答案将围绕这部分：

似乎您缺少一些 Tomcat 启动所需的依赖项。 Javadoc 异常的定义应该为解决这个问题提供更多见解：

https://docs.oracle.com/javase/7/docs/api/java/lang/ClassNotFoundException.html

你确定所有的 jar 文件都包含 Tomcat 所需的所有文件吗？另外，我强烈建议编辑您的原始问题，去掉大写字母并解决所有措辞问题，以使其更具可读性。

【讨论】：

（这看起来很有帮助，但我倾向于鼓励将元建议作为评论单独发布。这是因为 OP 或其他人有望解决帖子中的问题，留下用对未来读者无用的过时信息回答）。我会这样做，但评论部分不允许使用很多字符，最重要的是它不允许（或者我还没有找到如何做到这一点）正确的代码语法。根据你和tomcat关联的jar文件告诉我
