I can't read your screenshots too well, but it's not your fault. It's a combination of bad eyes and low-res monitor at my end. Even so, I can tell from the pictures that I would be doing what you're trying to do differently. Mine may not be the right way or yours the wrong - just different.
To "run" that jsp file on the
Tomcat server, I would open a browser and point to it using the address:
http://localhost:8080/projectname/filename.jsp
8080 - you may have changed this to another port as occasionally suggested by some
projectname - change this to you project name
filename.jsp - change this to the name of the jsp that you're trying to run
This assumes your server has been started, no errors, the project has been added to it, etc., etc. If there is something wrong with those assumptions, you'll get an error message from either the browser or the server to get you pointed in the right direction.
I apologize if my answer is limited by my own minimal experience. I'm new at this myself so struggling through many of the same adventures.
Also, I've been having good luck with the typical Eclipse setup, using Web Tools Platform (WTP) and Eclipse's otherwise built-in server support. I've seen others complain about the limitations or bugginess of that setup, recommending the sysdeo Eclipse plugin for Tomcat as a solution. I have no experience with sysdeo so can't recommend one setup over the other.
