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. It also provides a framework for integrating existing custom tags with JSTL tags.
The JSTL 1.2 Maintenace Release aligns with the Unified Expression Language (EL) that is being delivered as part of the JavaServer Pages (JSP) 2.1 specification. Thanks to the Unified EL, JSTL tags, such as the JSTL iteration tags, can now be used with JavaServer Faces components in an intuitive way.
JSTL 1.2 is part of the Java EE 5 platform.
