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:
“The degree to which the child-rearing professionals continue to be out of touch with reality is astounding. For example, a widely read manual on breast-feeding, devotes fewer than two pages to the working mother.”
—Sylvia Ann Hewitt (20th century)
“Any honest examination of the national life proves how far we are from the standard of human freedom with which we began. The recovery of this standard demands of everyone who loves this country a hard look at himself, for the greatest achievments must begin somewhere, and they always begin with the person. If we are not capable of this examination, we may yet become one of the most distinguished and monumental failures in the history of nations.”
—James Baldwin (1924–1987)
“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)
“A man’s library is a sort of harem.”
—Ralph Waldo Emerson (1803–1882)
