当我从 Eclipse 中的“服务器”选项卡启动 Tomcat v7.0 服务器时，出现一个问题消息框:
Starting Tomcat v7.0 Server at localhost has encountered a problem.
Server Tomcat v7.0 Server at localhost failed to start.
我是这方面的初学者，在 stackoverflow 上搜索了所有类似的问题，尝试了其他人给出的解决方案，但都没有用。我该怎么做才能解决这个问题？
web.xml 是
<?xml version="1.0" encoding="UTF-8"?>
<web-app xmlns:xsi="w3.org/2001/XMLSchema-instance" ; xmlns="java.sun.com/xml/ns/javaee" ; xsi:schemaLocation="java.sun.com/xml/ns/javaee java.sun.com/xml/ns/javaee/web-app_3_0.xsd" ; id="WebApp_ID" version="3.0">
<display-name>SimpleServletProject</display-name>
<servlet> <servlet-name>xmlServlet</servlet-name>
<servlet-class>org.swechchha.XmlServlet</servlet-class>
</servlet>
<servlet-mapping>
<servlet-name>xmlServlet</servlet-name>
<url-pattern>xmlServletPath</url-pattern> </servlet-mapping>
</web-app> –
日志在这里:
SEVERE: A child container failed during start
Caused by: java.lang.IllegalArgumentException: Invalid <url-pattern> xmlServletPath in servlet mapping
