}
}

i have checked the directory structure and it looks fine,kindly revert me asap.

dopost != doPost

This is Java. Case counts!

You are trying to POST the HTML page but there is no method in your servlet to handle this request.

As correctly pointed out in the previous post, here is the signature of the doPost method you should be using to handle POST requests:

Make sure you have the correct method in place and you should be fine.
