When I create any JSP file, I get the error "The superclass "javax.servlet.http.HttpServlet" was not found on the Java Build Path". I'm using Tomcat 10, so the proper class would be "jakarta.servlet.http.HttpServlet". I didn't have this error previously and nothing changed with my project, but I did update Eclipse which might have caused the problem. I reverted to my previous installs but the error persisted. My current Eclipse version is 2022-06 (4.24.0).

Which version of the Dynamic Web Module facet is set on your project? For jakarta.servlet.http.HttpServlet, it should be 5.0.

Not sure how it got changed, but that was the issue. It was set to 3.0. Thank you for the help.

Add a runtime first and select project properties. Then check the server name from the 'Runtimes' tab
