Overview

Introducing Web page authors and programmers to the JSP Standard Tag Library (JSTL), this guide covers all features of the JSTL 1.0 standard. Whether users need to add dynamic content to a static Web page or are in need of providing back-end code, nonprogrammers are shown how to manipulate XML, access relational databases, format text, internationalize Web applications, and introduce general-flow logic into JSP—all with HTML-like tags that are accessible to authors of Web pages. Also addressed are techniques for utilizing and extending JSTL's functionality.

JSTL is a Java standard for developing dynamic web sites. It gives non-programmers access to powerful operations through HTML-like tags. This makes JSTL an evolutionary step forward in simplifying the Javaweb platform.

introduces and shows off JSTL's capabilities. It include slots of useful code snippets so you can start using JSTL quickly. Large, working examples show you how to tie JSTL's features together. The book shows how to manipulate XML, use relational databases, format text, internationalize web applications, and an advanced part of the book covers configuration and integration of Java code with JSTL.

This book is written both for programmers and page authors. The coverage is comprehensive and still manages to guide the reader through the subject gently and with humor.

Editorial Reviews

From Barnes & Noble
The Barnes & Noble Review
The whole idea of JSTL is to make Java’s power accessible to anyone who builds or runs web sites, whether they’re programmers or not. JSTL in Action takes that promise seriously. Even if you only know HTML, this book can help you implement some pretty slick server-side functionality. And if you’re already a Java programmer, you’ll love its thoroughness and insight -- no surprise, since the author was lead developer on Sun’s JSTL reference implementation.

Shawn Bayern starts with an overview of the simple ideas behind dynamic web content; JSP and XML, JSTL’s foundation technologies; and JSTL’s goals. In Part II, he walks you through nearly every JSTL tag, starting with the most fundamental -- those that handle simple decisions and loops. Gradually, with easy examples, he covers importing text; working with XML fragments; using JSTL’s database support (even transactions); and formatting numbers, dates, and locales. Pay especially close attention to the chapter on JSTL expressions. If you’re using JSTL, you can’t rely on JavaScript for expressions. Fortunately, JSTL’s expression language is simpler than JavaScript’s -- especially the way Bayern explains it.

Part III presents case studies -- starting with “small-scale” tasks like error handling and input validation, but moving on to sophisticated layout management, RSS channel delivery, registration, authentication, and personalization. The book ends with coverage aimed specifically at Java professionals, including JSTL configuration and custom tag development.

We’d be remiss if we didn’t note that Bayern’s a terrific writer -- and that goes for both his narrative and his samples. Highly recommended. Bill Camarda

    Good book on JSTL

    Those interested in custom tags or third party tag libraries may want to purchase the book. Having read the official specification a dozen times or more, some of the finer details can be hard to grasp. JSTL includes alot of features, but specifications are often written for experts in the field and are not always obvious to those outside of the expert group. Even though I've been using JSP since 0.9 spec, there's plenty of valuable information contained in shawn's book. If you like to see examples of how things work, this book will help clarify a lot of ambiguities.
