Java Standard Template Library (JSTL)
JavaServer Standard Tag Library (JSTL) is a collection of JSP tags that simplify the development of Java web applications by providing common functionalities like iteration, conditionals, and formatting. It helps reduce Java code embedded in JSP pages, promoting cleaner and more maintainable views. JSTL supports core, XML, internationalization, and database tags for efficient page development.
Key Features of Java Standard Template Library (JSTL)
- Provides standard tags for common tasks like loops and conditionals
- Eliminates scriptlets in JSP, promoting cleaner code
- Supports internationalization and localization (i18n)
- Enables easy formatting of numbers, dates, and text
- Includes XML tags for parsing and transforming XML data
- Facilitates database access using SQL tags
- Works seamlessly with Expression Language (EL)
Before learning JSTL, you should have a good understanding of core Java and basic web development concepts. Familiarity with JSP (JavaServer Pages) and how web applications work is essential. Knowledge of HTML and Expression Language (EL) will also be beneficial.
