How Custom Tag Works

Conclusions:

• Custom tag is an action tag defined by the user through the JSP tag extension facility.
• Custom tag is independent of JSTL (JSP Standard Tag Libraries).
• All custom tag classes are extended from javax.servlet.jsp.tagext.TagSupport or javax.servlet.jsp.tagext.SimpleTagSupport.
• JSP pages access custom tags through TLD (Tag Library Descriptor) files.
