MacBookPro OSX v 10.4.11
NetBeans 6.0 (not important, except that provides ...)
apache-tomcat 6.0.14

HF Servlets & JSP (Chapter 3) written and, surprisingly, appears to compile!

http://localhost:8080/Beer-v1/form.html returns HTTP 404 - File not found

There is no doubt in my tiny, military mind that I have fat-fingered something somewhere and I have, so help me, examined every key stroke in every file in every directory in the dev and deployment directories.

And, clearly, I haven't figgered it out yet.

So, to get to the Topic, has anyone got troubleshooting tips? I;m looking for a system that I can use to finally track down and kill whatever bug is in my way that I can use over and over ...

Welcome to JavaRanch!

Have you check the Tomcat logs yet? They will help narrow down the problem. For example, you could see that the server started and the web app started (or didn't if something is wrong.)

Another troubleshooting tip is to try Tomcat's "welcome" page/URL to make sure Tomcat itself is working.

Ma'am, yes .. I did start at Tomcat welcome page ... and now that I've found catalina.out, I can see that I have a <BLUSH>fat-finger</BLUSH> in the web.xml

So, for the sake of completeness, in this case, the answer is in the apache logs, located at $TOMCAT_HOME/logs/catalina.out
