Hi,
I'm a relative Tomcat newbie. I have built an application with ant and
was using it under Tomcat 5.5.9 for several weeks, and then it suddenly
broke. All request to JSP pages now display the 404 error (the requested
resource is not available). I was making only very minor changes to the
Java code. The HTML pages still work.
There are no errors in catalina.out and localhost.log. I've tried to
configure log4j logging by placing the log4j.properties file into
common/classes (and the commons-logging and log4j jars into common/lib,
but the log file I specified there is not even created.
Finally, I was never able to make my application work with the web.xml
file generated by ant. It only worked after I delete the file. The file
is pretty basic, but I attach it in case there is an obvious error there.
I'll be grateful for any suggestions.
Thanks,
Simon

<!-- Servlet definitions for the servlets that make up

to servlets not listed here with a request like this:
http://localhost:8080/{context-path}/servlet/{classname}

makes relative references to images and other resources
required by your servlet more complicated, so defining
all of your servlets (and defining a mapping to them with
a servlet-mapping element) is recommended.

<description>
This servlet plays the "controller" role in the MVC architecture
used in this application. It is generally mapped to the ".do"
filename extension with a servlet-mapping element, and all form
submits in the app will be submitted to a request URI like
"saveCustomer.do", which will therefore be mapped to this servlet.
The initialization parameter namess for this servlet are the
"servlet path" that will be received by this servlet (after the
filename extension is removed). The corresponding value is the
name of the action class that will be used to process this request.

This servlet produces GIF images that are dynamically generated
graphs, based on the input parameters included on the request.
It is generally mapped to a specific request URI like "/graph".

<!-- Define mappings that are used by the servlet container to
translate a particular request URI (context-relative) to a
particular servlet. The examples below correspond to the
servlet descriptions above. Thus, a request URI like:
http://localhost:8080/{contextpath}/graph
will be mapped to the "graph" servlet, while a request like:
http://localhost:8080/{contextpath}/saveCustomer.do
will be mapped to the "controller" servlet.
You may define any number of servlet mappings, including zero.
It is also legal to define more than one mapping for the same
servlet, if you wish to.
