Subject: [Newbie] Failed access to servlet via URL mapping (context setting problem?)
Mac OSX 10.3.7; Tomcat 5.5.4; JDK 1.4.2; compat installed
I have installed Tomcat 5.5.4 with a view to using it to implement a web-based interface to a MySQL database.
I began by following the guidelines here: http://developer.apple.com/internet/java/tomcat1.html, but as these related to V4 of tomcat, this has served to trip me up a little. I could not get any of the example servlets to function by following the directions given.
I subsequently found further guidelines here: http://www.coreservlets.com/Apache-Tomcat-Tutorial/, I have got to the point where I can run all of the sample servlets described there. These involve directly copying resources into the $CATALINA_HOME/webapps/ROOT/WEB-INF(/classes) directories.
I could now develop my application and copy it to the ROOT directory and access it through a URL like localhost:8080/hi, but this seems like poor structure to me. I could also place the app in a subdirectory and access it with localhost:8080/hi/servlet/hi, but that is not too tidy.
What I would like to do, and what I think is possible, is somehow to advise tomcat of the location of my webapp in its own directory (not under ROOT) and access it with localhost:8080/hi.
No amount of tweaking servlet mappings and URL patterns has worked, and I suspect that somewhere I need to have a <context> element. (I admit to confusion over the apparent need to specify the path both in the context and the servlet mapping, so I've missed a big point somewhere). The nearest I have got is to obtain an empty "Directory listing for /" page in response to my http://localhost:8080/hi request. I enabled request logging and obtained the following:Created MBeanServer with ID: c3e82b:10179d228c6:-8000:XarqiMac.local:1

The line:INFO: servletPath=/suggests to me that somehow the URL (/hi) is not being passed through as I would hope.
If someone could take the time to point a newbie in the right direction, I'd be very appreciative.
Thanks.
