Tomcat 4.1中出现的错误一例
SEVERE: Parse Error at line 5 column 19: Document root element "web-app", must match DOCTYPE root "null".
org.xml.sax.SAXParseException: Document root element "web-app", must match DOCTYPE root "null".
SEVERE: Parse Error at line 5 column 19: Document is invalid: no grammar found.
org.xml.sax.SAXParseException: Document is invalid: no grammar found.
偶用的是Tomcat 4.1.24+MyEclipse,结果在新建一个项目中出现了如上问题,郁闷了好久,查阅资料若干,最后总结如下:
我到网路上查,看见说是Tomcat 4.xx should use the 2.3 DTD spec ,If you're using the 2.4 spec, you'll need Tomcat 5.
确实web.xml中用的是2.4 spec。

org.apache.commons.digester.Digester error SEVERE: Parse Error at line 6
column 19: Document root element "taglib ", must match DOCTYPE root "null ".
org.xml.sax.SAXParseException: Document root element "taglib ", must match
DOCTYPE root "null ".

So, I tryed finding the error looking through the tld files, googling a bit
and so on, until I tryed removing the jstl.jar and standard.jar from my
web-applications. Suddenly no error was reported.
结论:Tomcat4.1.24中是Servlet2.3规范,不支持2.4规范,因此如果在项目中添加了jstl.jar或者项目的web.xml中出现2.4规范,就会报如上的错误
