Answer 1

Looks pretty straightforward to me. The class com.thetravel.ld.tools.efund.servlets.HIMain is registered as a servlet called "main", but it doesn't implement javax.servlet.Servlet (ie it isn't a servlet).

Answer 2

Either HIMain doesn't extend GenericServlet or HttpServlet , or your application is including its own copy of the Servlet API. The latter can cause classloading problems like this one.

Make sure you don't have servlet-api.jar (or something like it) in your application.
