• Key Concepts: 
  A JSP tag handler is a Java class that is used to process custom tags in a JSP page. It is part of the JavaServer Pages (JSP) technology, which is a server-side technology used to create dynamic web pages. The tag handler is responsible for generating the output of the custom tag and for providing access to the attributes of the tag. 
  
  How to use it: 
  To use a JSP tag handler, you must first create a tag library descriptor (TLD) file that contains information about the custom tags. This file must be placed in the WEB-INF directory of your web application. Then, you must create a Java class that implements the javax.servlet.jsp.tagext.Tag interface and register it in the TLD file. Finally, you can use the custom tag in your JSP page by referencing it in the TLD file. 
  
  Tips & Tricks: 
  When creating a JSP tag handler, it is important to remember that the tag handler must be thread-safe and should not contain any state information. Additionally, it is important to ensure that all resources used by the tag handler are properly released when it is finished processing.
