newbie Tomcat question

[Baba]

Hi.

I have recently downloaded a war file of a web application which I need to
use for my college project. I followed the deployment instractions (which
were to unzip the war in the %CATALINA_HOME%/webapps directory) which I did.
However, on trying to run the application, I repeatedly get the 404 Error.

The only thing that I'm not sure about is that the needed jars for running
the application are not exactly accurate. To be more precise, the
application is a year old and I guess it uses older version of e.g. Xalan,
Xerces etc.

My question is this: is it possible to get a 404 Error because one of the
libraries the application uses is missing or is newer then expected? Or the
error has to be in an web.xml file, since it obviously complains that it
cant find the application, not an error in running it?

Thank you in advance.

(UPDATE)

I tinkered a bit and got a 503 - servlet currently unavailable error. Now I
am even more baffled then before.

Is there any way to get more debugging information from Tomcat??
