I have made one tag related web app from the HFSJ book from chapter:9. My application can deploy but its not running, it says "javax.servlet.ServletException: java.lang.NoClassDefFoundError: com/example/web/Advicor (wrong name: Advicor)". I made "Advicor" named class instead of "AdvisorTagHandler". I put that in a proper directory then why it gives me this error. Anyone had a same problem like me to run web app, please help me.
