About JSTL The JavaServer Pages Standard Tag Library (JSTL) encapsulates as simple tags the core functionality common to many Web applications. JSTL has support for common, structural tasks such as iteration and conditionals, tags for manipulating XML documents, internationalization tags, and SQL tags.

JSTL integration is built into the framework - there are no steps required to enable it. Simply refer to your JSTL expressions just as you would with a normal SAF JSP tag, such as the property tag.
