Hello! I'm having a web application perfectly running on tomcat 3.x Now, I'm trying to switch to new tomcat version 4. I'll recompiled code with new servlet API (no changes were necessary).
Although I'm getting an exception, that my Servlet (extends HttpServlet) is not a Servlet: javax.servlet.ServletException: Class com.quarksolutions.interad.admintool.AdminToolMainServlet is not a Servlet
Root Cause:
java.lang.ClassCastException:
com.quarksolutions.interad.admintool.AdminToolMainServlet

I've definitely checked, that there are no old serlvet API is around and there are no other "Servlet" classes around. Does anybody have an idea how this is possible?
Any help is apreciated!
Thanx, Markus Albrecht
