JSTL for Not Yet Techies

"Computer Careers: Developing Server-Side, Interactive Java Applications for the Internet"

by Richard Stooker, President Info Ring Press and author of Secrets of Changing to a Computer Career

JSTL stands for JSP (Java Server Pages) Standard Tag Library. JSP is Java version of Microsoft's Active Server Pages technology that lets you make web pages more interactive by embedding Java code into HTML files. The JSTL contains built-in tags and extensibility that allows you to build the web pages more easily than with JSP alone.

JSTL is for server-side Java, and makes JSP easier because that mixes presentation and business logic. It works only with servlet containers that support Servlet 2.3 and JSP 1.2 APIs.

Based on ECMAScript and XPath, JSTL reduces the need for JSP expresions and scriptlets

Its formatting actions let you internationalize web sites, an important concern as the number of non-English speaking Net users keeps growing. You don't want to lose customers just because they don't read English.

Although up until now most Net surfers whose native language is not English have been relatively highly educated and therefore at least able to grasp written English (because it's taught throughout the world and many school systems actually teach small child IN English), that is changing as Net access spreads to even isolated rural areas of the world. JSTL is one tool to help you let potential customers know that you're interested in helping them in their own language.

JSTL is an expressive language, contains Standard Action Libraries and Tag Library Validators.
