The documentation for actually adding the most basic of servlets is a bit sketchy so I tried 'reverse-engineering' the example servlets. I got it so I have a folder with a basic Hello, World servlet. I wrote and compiled a servlet to test but I guess my deployment is off.
Whenever I comment out the <servlet> and <servlet-mapping> sections for the 'HelloServlet' section, the 'HelloWorldExample' servlet works just fine. When I try running the Tomcat server without the comments, both servlets throw a 503.
It would seem that there is something I'm doing wrong with my XML since this fixes/breaks it. Does anyone know what exactly I have wrong?
Never mind this. The issue was the JRE Tomcat was using. (Note: I would delete the post, but I don't know how)
