New to JSP and Servlet - Struggling with database

New to servlet and JSP (Maven project) using tomcat 11.0.1

Hi there,

I'm new to Servlets and JSP, and I'm feeling a bit stuck. I'm having trouble retrieving items from a database and displaying them on a JSP page. I think I might be missing something, but I'm not sure what.

Any tips or guidance would be greatly appreciated!
