One way to develop dynamic page content on a web application is to use JavaServer Pages technology. This allows you to embed bits of Java code, or scriptlets, within the HTML page. The web server interprets the scriptlet when the page is called and produces the content that is coded. This is all good, but there are common tasks (such as looping) that each developer had to reinvent from scratch each time it was used in a page. To prevent this repetitive coding, a common set of JSP tags were created to allow developers to concentrate on business logic instead of coding structures. This creation is known as the JSP Standard Tag Library (JSTL). That's what this book is all about...
The book starts with an examination of how JSP and XML tags come together to form the basis of JSTL. This is followed by a number of chapters that cover the different tags that are used to control branching, flow, text formatting, and other various structures. After the basics of JSTL, the author looks at a number of common tasks encountered by JSP developers and how they would be coded using JSTL. Finally, the book wraps up with reference data needed on a regular basis as you use JSTL, such as the API.
The writing is clear and concise, with an abundance of diagrams and code to illustrate the points. The mix of reference, tutorial, and practical examples is perfect, and every developer will be able to use this book in a number of situations.
Websphere developers (both web application and portlet development) will get the most out of this book when it comes to the IBM/Lotus world. The use of JSTL will reduce the code complexity of your JSP pages and speed up your development efforts.
If you are developing JSP pages and haven't looked into the use of the JSTL area, get this book. It will save you time and effort in your coding, and you'll be glad you did.
