What Is a Custom Tag?
A custom tag is a user-defined JSP language element. When a JSPpage containing a custom tag is translated into a servlet, the tag isconverted to operations on a tag handler. The web container then invokes thoseoperations when the JSP page’s servlet is executed.
Custom tags have a rich set of features. They can
Be customized by means of attributes passed from the calling page.
Pass variables back to the calling page.
Access all the objects available to JSP pages.
Communicate with each other. You can create and initialize a JavaBeans component, create a public EL variable that refers to that bean in one tag, and then use the bean in another tag.
Be nested within one another and communicate by means of private variables.
