Obtaining Textfield Input from the User

This free, multimedia tutorial shows you how to use IBM's Rational Application Developer (IRAD) 6.0 to create an HTML file containing a form. Once the user submits the form, a Servlet is invoked, and the contents of the textfields of the form are read on the server side by the Servlet in question.
