I'm new to tomcat and I've been tearing my hair out for the past week trying to get the simplest examples to run.
I'm running a clean install of tomcat 4.1.27, and have been able to run the struts-examples, the admin webapp (to my great surprise), and even some of the examples from my struts textbook.
the problem i've been having is understanding the error messages so that i can figure out what's wrong.
Is there any way of getting better/different errors than simply just the HTTP/50x messages? Is there a way to trace execution through the program? How difficult is it to set up a debugger to work with tomcat, so that I can see what line is causing the server to choke?
this is my log file from a recent attempt at playing with struts, can someone please help, and tell me what this means:
