OK. That will be relying on the StandardJarScanner finding that class -
which it should.

OK. Maven is copying that to META-INF/resources and hoping that Tomcat
will treat the entire JAR as a resource JAR. That should work.

Not sure which part is failing at this point. Using a purely static JSP
without the forward and accessing /employee directly should tell you which.
I'd then recommend debugging your way though the Tomcat start process to
see where whichever element is failing is going wrong.
