java.lang.ClassNotFoundException: jakarta.servlet.jsp.JspFactory
Hi Chris,
I have forwarded you that SO URL to showed you that the scope provided needed
to add it in but after you pointed out I realised it is wrong.
Nope. I am not using jetty run. I right click on Eclipse run on server.
So, the latest happening is that I got an advice from another SO user to put in
the jar from Download jakarta.servlet.jsp-api JAR file with all dependencies
I tried to exploded the jar to see if it contains all the dependencies I need
but all i could find is byte code .class.

and Tomcat is able to run. Only thing is that the index.jsp doesn't show up.
It only show localhost:8080/webclientv1/ and the browser appears moving like
waiting.
But, still I got to sort out the dependencies cos I need them for CICD.
Could you advise me what is the full set of dependencies I need ?
Tks.

If you are using jetty:run then you are probably not using Tomcat. >:|
