The JavaServer Pages Standard Tag Library (JSTL), is a component of the Java EE Web application development platform. It extends the JSP specification by adding a tag library of JSP tags for common tasks, such as XML data processing, conditional execution, loops and internationalization. JSTL was developed under the Java Community Process (JCP) as Java Specification Request (JSR) 52. On May 8, 2006, JSTL 1.2 was released.
JSTL provides an effective way to embed logic within a JSP page without using embedded Java code directly. The use of a standardised tag set, rather than breaking in and out of Java code, leads to more maintainable code and enables separation of concerns between the development of the application code and user interface.
In addition to JSTL, the JCP has the following JSRs to develop standard JSP tag libraries:
- JSR 128: JESI – JSP Tag Library for Edge Side Includes (inactive)
- JSR 267: JSP Tag Library for Web Services
Famous quotes containing the words pages, standard, tag and/or library:
“Perhaps these pages are more particularly addressed to poor students. As for the rest of my readers, they will accept such portions as apply to them.”
—Henry David Thoreau (1817–1862)
“This unlettered man’s speaking and writing are standard English. Some words and phrases deemed vulgarisms and Americanisms before, he has made standard American; such as “It will pay.” It suggests that the one great rule of composition—and if I were a professor of rhetoric I should insist on this—is, to speak the truth. This first, this second, this third; pebbles in your mouth or not. This demands earnestness and manhood chiefly.”
—Henry David Thoreau (1817–1862)
“I believe in the flesh and the appetites,
Seeing, hearing, feeling, are miracles, and each part and tag of me
is a miracle.
Divine am I inside and out, and I make holy whatever I touch or am touch’d from,
The scent of these arm-pits aroma finer than prayer,
This head more than churches, bibles, and all the creeds.”
—Walt Whitman (1819–1892)
“I view askance a book that remains undisturbed for a year. Oughtn’t it to have a ticket of leave? I think I may safely say no book in my library remains unopened a year at a time, except my own works and Tennyson’s.”
—Carolyn Wells (1862–1942)
