修改web.xml后，启动tomcat5失败
在我修改web.xml文件之前，啟動tomcat5正常，在我修改后，就出現錯誤了，再啟動weblogic，也是正常的，為什么？謝謝大家。（我用的是myeclipse) 
錯誤信息如下： 
2007-10-13 16:04:11 org.apache.catalina.startup.ContextConfig applicationConfig 
严重: Occurred at line 9 column 19

web.xml 

<web-app> 
<servlet> 
<servlet-name>HelloWorld</servlet-name> 
<servlet-class>com.test.HelloWorld</servlet-class> 
</servlet> 
<servlet-mapping> 
<servlet-name>HelloWorld</servlet-name> 
<url-pattern>asdf</url-pattern> 
</servlet-mapping> 
</web-app>

楼上正解.
------解决方案--------------------
你应该在<web-app > 前面加上：
<?xml version="1.0" encoding="utf-8"?>
<!DOCTYPE web-app PUBLIC "-//Sun Microsystems, Inc.//DTD Web Application 2.3//EN" "http://java.sun.com/dtd/web-app_2_3.dtd">
然后再接上<web-app>
最后注意的就是你的<url-pattern >asdf</url-pattern > 处理路径一定要写对！
------解决方案--------------------
<servlet-mapping >
<servlet-name >HelloWorld </servlet-name >
<url-pattern >/asdf </url-pattern >
</servlet-mapping >
