求助，有关TOMCAT

[liujunxiaose]

之前一直用的SERVLET2.3，最近学过滤器，想测试下过滤器的工作流程，创建过滤器后，写XML文件有的配置项写不了，就新建了个工程，选了JDK5，servlet2.5，但是启动Tomcat后报错，加载不了servlet，我用的Tomcat6.0,错误代码如下

java.net.UnknownHostException: java.sun.com

看起来是企图去SUN的网站上下载DTD来验证web.xml的正确性了。。。


你检查下web.xml第一行是不是：
<!DOCTYPE web-app
PUBLIC "-//Sun Microsystems, Inc.//DTD Web Application 2.2//EN"
"http://java.sun.com/j2ee/dtds/web-app_2_2.dtd">

删除掉它吧。

你太牛逼了 以后不要直接把所有信息都帖出来了 重要的是错误那里 Parse error in application web.xml file at jndi:/localhost/Test/WEB-INF/web.xml 其实就是说解析web.xml时发生了错误 检查一下你的web.xml配置文件就能发现错误了
