Hi
   Using request.getParameter("<fieldname>") you will get the values to the page.

Then you can use those values in your insert statement. These things should be done in doPost() or doGet() method depending on the submission method.

Hi
  get method will append all the form data in the url itself. also there will be a limit on size of data that is submitted in get.

In post you wont see the values in the url that are being submitted. also there is no limit on the size of data being send.

You have to use doGet() for get submission and doPost() for post submission
