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!

Giving this kind of error?

szatkus•4w ago

Hard to say what threw the exception.

Users of Tomcat 11 onwards should be aware that, as a result of the move from Java EE to Jakarta EE as part of the transfer of Java EE to the Eclipse Foundation, the primary package for all implemented APIs has changed from javax.* to jakarta.*. This will almost certainly require code changes to enable applications to migrate from Tomcat 9 and earlier to Tomcat 11 and later. A migration tool has been developed to aid this process.

But it seems you have Jakarta everywhere?

LithorOP•4w ago

yeah i'm trying to use jakarta but it keeps saying i have to use jakarta instead of javax i didnt use javax in my project?

szatkus•4w ago

Could happen if you have some dependency that tries to load javax.

LithorOP•4w ago

Ah, i see well the problem is i don't see the dependecy that tries to use javax :/
