java - Tomcat 7 问题 - 无法启动服务器实例

Question

我创建了一个新的服务器实例，并修改了 server.xml，添加了 <Context> 标记以将其指向我的应用程序。

我启动服务器，我得到这个:

Server Tomcat v7.0 Server at localhost was unable to start within 45 seconds. If the server requires more time, try increasing the timeout in the server editor.

如果我删除添加的 <Context> 标签，它就会启动。

这是server.xml

一些细节:

1. 服务器运行环境JRE设置为jdk1.7.0
2. 我正在使用 Eclipse Juno

我错过了什么？

我必须向 pom.xml 添加什么才能使其正常工作？

Answer 1

引起:java.lang.NoClassDefFoundError:javax/faces/webapp/FacesServlet

您缺少face servlet的jar文件，请确保它们位于您的tomcat lib文件夹中或至少是java路径的一部分
