"Isn't work" is not enough to guess what is wrong. Is there an error message? What do the server's logs say? Read the web server's documentation on how to install servlets.

i used Myjavaserver for jsp files n was successfully able to run those

but when i tried servlets it doesnt run

err msg-

Not Found

The requested URL /~touchdstar/touchdstar/HelloWorldServlet was not found on this server.

Installation how to says-

class files can be kept anywhere but should have package name as username

Servlet container mappings:

Servlets /servlet/*

JSP *.jsp

Apache Cocoon *.cocoon.xml

I started to learn servlets n jsp lately n can run it on tomcat but dont understand where m i going wrong on myjavaserver

can anybody tell me abt this?
