Classes and interfaces for the definition of Jakarta Pages Tag Libraries.

The Jakarta Pages specification provides a portable mechanism for the description of tag libraries.

A JSP tag library contains

  • A Tag Library Descriptor
  • A number of Tag Files or Tag handler classes defining request-time behavior
  • Additional classes and resources used at runtime
  • Possibly some additional classes to provide extra translation information

The JSP 2.0 specification and the reference implementation both contain simple and moderately complex examples of actions defined using this mechanism. These are available at JSP's web site, at Some readers may want to consult those to get a quick feel for how the mechanisms work together.
