This started out being a question about configuring a custom 404 error page when the URL doesn't match a webapp context, but has morphed.
I have Tomcat 6. I haven't actually deployed my web app yet. I've got the docs app, the manager app, and the "Welcome to Tomcat!" ROOT app.
Regarding my original problem, adding a simple custom error html page and adding the <error-page> element to web.xml didn't work (still get tomcat default 404 page with http://localhost:8080/anything).
All of these are related to the display of the welcome page.
Nothing else displays.
Now, it's quite possible that I hosed something while playing around trying to figure out where to put the custom error pages, but WHAT could I have hosed? I've tried removing the temp file, removing the work file, restarting tomcat.
This is very frustrating, not to mention a big waste of time for something so simple.
