I have a simple HelloWorld class. I placed it in c:/installdir/webapps/root/web-inf/servlets directory(as suggested by core servlets book). When I use http://localhost/servlet/HelloWorld it never opens the page. Any suggestions.(I also moved this file to c:/installdir/webapps/root and tried to run. It did not work. My class path does not contain above direcotories. Does it matter. Kishore.
