JSTL stands for JSP Standard Tag Library which is a collection of very useful core tags and functions. These tags and functions will help you write JSP code efficiently. JSTL has support for common, structural tasks such as iteration and conditionals, tags for manipulating XML documents, internationalization tags, and SQL tags.
