Developing JSP Custom Tags - Project (Continue...)


Custom tags are distributed in a tag library, which defines a set of related custom tags and contains the objects that implement the tags. The object that implements a custom tag is called a tag handler.

JSP technology defines two types of tag handlers: simple and classic.
Simple tag handlers can be used only for tags that do not use scripting elements in attribute values or the tag body.
Classic tag handlers must be used if scripting elements are required.
