What are Custom Tags in JSP? How do you create it?

The custom tags are just user-defined elements that are converted into some operation on an object when the JSP is translated into a servlet. Custom tags are instantiated from the SimpleTagSupport class. With this, scriptlet tag use is removed. And also, the custom tags can be reused.

To create a custom tag in jsp, do the following steps.

• Create the tag handler class and override the doStartTag() method.
• Create the TLD file which contains information about the tag and the tag handler class.
• Create the JSP file and use the created tag in it.
