Also, all servlets and other Java classes should be in packages other than the default. -----------------------
thanks bear, but the doubt is not cleared. I have removed the SRC from the WEB-INF and i am not keeping the servlet in default package. under webapps i did create the directory for servlet program it would be great if you could elaborate the clarification.
