Subject Re: Re: Web demo example: Errors from Tomcat startup
Date Thu, 07 Feb 2002 14:23:02 GMT
I'll take a look at the confusing instructions on demo3.  I have no idea why
the dtd isn't validating.  Can anyone else answer this?

You might want to pose the dtd problem to the tomcat-user mailing list.  Due
note that I make the assumption you're using 4.0.x or know how to adapt it. 
I'd guess if you take that top line and replace it with the top line from
one of the tomcat 3.2.x example web.xml files, you'll probably hit paydirt. 
Probably tomcat can't read the newer format.  (but the file is practically
blank anyhow).
