First, create a web page with an HTML form. Then, create a servlet. Make the action of the form on the web page refer to the URL of the servlet, so that the form is submitted to the servlet. Set the method attribute of form to "POST".

In the servlet, implement a doPost() method. Use request.getParameter(...) to get the information that's in the submitted form. Use JDBC to insert the information into a database.

You can find tutorials about servlet programming or JDBC on Internet, or in a book like Head First Servlets & JSP.
It is sorta covered in the JavaRanch Style Guide.
