Tomcat无法在eclipse上启动
问题描述：
在Eclipse中的Java EE项目中启动tomcat 7.0时遇到了一些问题。启动服务器时出现超时错误。 我还没有弄清楚什么是错的。 我尝试将超时限制增加到1800s，但不会改变任何内容。Tomcat无法在eclipse上启动
这里是日志当Tomcat尝试启动：

感谢您回应

具体来说，Tomcat作为成功启动（在你的堆栈跟踪的最后一行所示）的应用程序服务器这是名为test的Web应用程序无法部署为丢失的依赖（Apache的库）作为的结果你可以从
Failed to start component [StandardEngine[Catalina].StandardHost[localhost].StandardContext[/test]] Caused by: java.lang.NoClassDefFoundError: Lorg/apache/commons/logging/Log;
看到here
下载缺少的依赖性，以免后患，复制你从上面的链接下载的公共图书馆罐子并将其放置在日e WEB-INF\lib部署包（文件夹或.war文件）的test文件夹。
另外，
下载并安装Apache下议院从共享网站here和日志库的最新副本复制到TOMCAT_HOME\common\lib文件夹（如果它不存在，创建路径）。 TOMCAT_HOME是指你的tomcat安装文件夹。不要将罐子复制到多个地点，这会在以后造成问题
答
Tomcat是无法启动由于安装的web应用的丢失的依赖。 从您的堆栈跟踪（去除的嗡嗡声：P）

尝试删除所有已部署的Web应用程序，并重新开始。如果Tomcat会启动，那么你可以试着弄清楚你的web应用程序导致了哪些混乱。
