The BodyTag interface extends IterationTag by defining additional methods that let a tag handler manipulate the content of evaluating its body.
For a tag to declare that it accepts dynamic attributes, it must implement this interface.
The IterationTag interface extends Tag by defining one additional method that controls the reevaluation of its body.
Serves as a base class for Tag and SimpleTag.
Interface for defining Simple Tag Handlers.
The interface of a classic tag handler that does not want to manipulate its body.
The auxiliary interface of a Tag, IterationTag or BodyTag tag handler that wants additional hooks for managing resources.
An encapsulation of the evaluation of the body of an action so it is available to a tag handler.
A base class for defining tag handlers implementing BodyTag.
Information for a function in a Tag Library.
Encapsulates a portion of JSP code in an object that can be invoked as many times as needed.
Translation-time information on a JSP page.
A base class for defining tag handlers implementing SimpleTag.
Wraps any SimpleTag and exposes it using a Tag interface.
Information on the attributes of a Tag, available at translation time.
The (translation-time only) attribute/value information for a tag instance.
Optional class provided by the tag library author to describe additional translation-time information not described in the TLD.
Tag information for a tag file in a Tag Library; This class is instantiated from the Tag Library Descriptor file (TLD) and is available only at translation time.
Tag information for a tag in a Tag Library; This class is instantiated from the Tag Library Descriptor file (TLD) and is available only at translation time.
Translation-time information associated with a taglib directive, and its underlying TLD file.
Translation-time validator class for a JSP page.
A base class for defining new tag handlers implementing Tag.
Variable information for a tag in a Tag Library; This class is instantiated from the Tag Library Descriptor file (TLD) and is available only at translation time.
A validation message from either TagLibraryValidator or TagExtraInfo.
Information on the scripting variables that are created/modified by a tag (at run-time).
The JavaServer Pages(tm) (JSP) 2.0 specification provides a portable mechanism for the description of tag libraries.
A JSP tag library contains
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 http://java.sun.com/products/jsp. Some readers may want to consult those to get a quick feel for how the mechanisms work together.
