Seenu,
Note: the embedded HTTP server is automatic with the startup of WAS 4.0 (i.e. you do not start it and stop it manually. As far as I know, you can't even do this with the embedded server).
The internal (embedded) HTTP server is automatically part of the WebSphere Application Server (i.e. not a seperate install). The IBM HTTP Server is the external one, which uses the plugin-cfg.xml. You don't need to mess with the external HTTP server with AEs for development ... and learning.
Can you run the admin console. /localhost:9090/admin
If so, I bet your problem is a
jsp or
servlet mapping problem for your application.
