I haven't done any JSP work in years, so I can't help you with that part, but the above error is a 404. That means that the server cannot find the file you are looking for, so double check the filepath to make sure the jsp page is located there.
A simple test can be done to verify your JSP is operational:
<h1><% out.println("Hello World!") %></h1>
If that shows the hello world! message, your JSP is good to go.
