Now that the basics are done with, it's time to begin applyingthat theory to Web development. This week, The JSP Files investigates theJSP Request object, and demonstrates how it can be used to process formdata. Learn about JSP's array variables, find out what chocolate chipcookies and couch potatoes have in common, and explore a very unusualpharmacy.
Last time out, we gave you a crash course in the numerous controls structures available to you in JSP - operators, conditional statements, and loops. But there's a big difference between learning theory in a classroom and actually practicing it in the real world - which is why this issue of The JSP Files is devoted to a discussion of how JSP can be used to extract and use data from HTML forms.
Over the next few pages, we're going to show you how JSP can be used to process the data entered into a Web form - everything from simple text boxes to lists and checkboxes - and we're also going to demonstrate how to use array variables in JSP.
