Tomcat:部署时的 LifecycleException [英] Tomcat: LifecycleException when deploying

问题描述

我刚刚在我的 Ubuntu 11.10 上下载了 Tomcat 7.0.23 包.

I just downloaded the Tomcat 7.0.23 package on my Ubuntu 11.10.

我按照 Google API 网站上的说明部署他们的示例网络应用.它基本上由放置在 WEB-INF/lib 目录中的 jar 文件和放置在 WEB- 目录中的 web.xml 文件组成.INF 目录.

I followed the instructions on a Google API website to deploy their example webapp. It basically consists of jar files placed in the WEB-INF/lib directory and a web.xml file placed in the WEB-INF directory.

但该应用程序并未自动部署，当我尝试强制服务器通过管理器 gui 部署它时，我收到以下消息:

Yet the app is not automatically deployed and when trying to force the server to deploy it through the manager gui, I get the following message:

FAIL - Application at context path /myWebApp could not be started
FAIL - Encountered exception org.apache.catalina.LifecycleException: 
         Failed to start component 
         [StandardEngine[Catalina].StandardHost[localhost].StandardContext[/myWebApp]]

但是，Tomcat 提供的 JSP 示例确实有效！

However, the JSP examples provided with Tomcat do work!

我在 Tomcat6 上也有同样的问题.

I have the same problem on Tomcat6.

那我做错了什么?这是权限问题吗?(我什至尝试将所有文​​件的 mod 更改为 777).

So what did I do wrong ? Is this a permission problem ? (I even try to change the mod of all files to 777).

推荐答案

这意味着您的应用程序配置或启动有问题.

This means something is wrong with your application configuration or startup.

日志中总是有相关信息 - 检查 logs/catalina.out 并找出问题所在.

There is always information about that in the logs - check logs/catalina.out and figure out what is wrong.
