Well, it's very strange - it means org/apache/tomcat/resources/web.dtd is not
present in webserver.jar or classes or the class loader can't read it.

Please check that you do have the file first.

No, this shoulnd't be an issue.

Tomcat should work stand-alone without any problem, and it shouldn't even
try to connect  to java.sun.com to get the DTD - it should use the local
copy.

How it works:
- WebXmlReader set up the parser to look for
org/apache/tomcat/resources/web.dtd
- SAX parser finds the external reference and calls the handler
- the sax handler will try to load the resource ( using
Class.getResourceAsStream())

The message show that all this happens, but getResourcesAsStream() returns
null.
This shouldn't happen - either the file is not present or the class loader
have big
problems.

Are you using Win9x or WinNT?

I know that running Tomcat (and even JSWDK) on Win9x is _really_ sensitive
to the internet settings. It's something to do with DNS being broken when
not connected to the internet or something, but from what I can recall its
pretty hard to figure out whats really going on, I remember even localhost
stops working...! I've never used NT under dialup so I'm not sure if it has
the same problems, probably not since I think the TCP/IP stacks are
different... (apparently WinMe (yuck) has the same TCPIP as NT)

Does anyone know the real story of what happens with Tomcat, Win9x and
connecting to the internet? I'd really like to hear the details if anyone
does...

cheers
