what is the use of JSTL in java

01-May-2023JSTL (JavaServer Pages Standard Tag Library) is a collection of custom tags that provide a standard way to access and manipulate data in JavaServer Pages (JSP). It is a standard component of the Java Enterprise Edition (J2EE) platform and is used to simplify JSP development by providing reusable, pre-built tags that perform common tasks.
JSTL includes a set of tags for core functionality, such as iterating over collections, conditionally displaying content, and formatting data. It also includes tags for working with XML documents, handling internationalization, and performing database queries.
JSTL tags are written in XML and are processed by a JSTL-enabled JSP container. The container interprets the tags and generates the appropriate HTML, which is sent to the client's web browser.
JSTL is designed to be used in conjunction with other web development technologies, such as Servlets, JavaBeans, and JSPs. It provides a way to separate the presentation layer of an application from the application logic, which promotes code reuse, makes maintenance easier, and makes it possible to change the presentation layer without affecting the underlying logic.
In summary, JSTL is a collection of tags that provide a standard way to access and manipulate data in JSPs, and it is a key component of the J2EE platform. It simplifies JSP development, promotes code reuse, and separates the presentation layer from the application logic.

20-May-2011The JavaServer Pages Standard Tag Library (JSTL) encapsulates, as simple tags, core functionality common to many JSP applications. For example, instead of suggesting that you iterate over lists using a scriptlet or different iteration tags from numerous vendors, JSTL defines a standard
JSTL has support for common, structural tasks such as iteration and conditionals, tags for manipulating XML documents, internationalization and locale-sensitive formatting tags, and SQL tags. It also introduces a new expression language to simplify page development, and it provides an API for developers to simplify the configuration of JSTL tags and the development of custom tags that conform to JSTL conventions.
