Edit: Yeah I totally mis-read, its not a tomcat config problem, its just that his servlet-api.jar isnt on his class path. He's trying to compile :/. My below still applies on setting up eclipse to do a web project though, it would automatically link the servlet-api.jar using the app server to let him compile.

When using eclipse they have a customised J2EE version of eclipse, but really it just supplies extra tools. In the J2EE version of eclipse you can create application servers using the run dialog (so basically you point eclipse at the location of your app servers), when you create a new dynamic web project using eclipse you also have to tell it what app server it will use and it will import the J2EE classes from your app server's folder, at least it's been that way for me.
--- Ignore all this because its not a tomcat config problem ---
I can't offer a solution to the OP because I'm a bit stumped because he seems to have the servlet-api.jar there. He's set up two useless environment variables though.
I could be wrong of course.
@OP
What version of tomcat, where did you download it from, are you running tomcat via the startup batch script or as a daemon?
P.S all that said I think that servlet-api.jar could just be interfaces, but certainly tomcat has to implement those interfaces concrete, I think that may be done in catalina.jar.
