The taglib directive in JSP is used to declare a set of custom tags defined in tag libraries that are used in the JSP page. It must be placed at the top of the JSP page and specifies the location of the tag library descriptor (TLD) file and the prefix to use when referencing the custom tags within the page. This allows developers to use custom tags in their JSP pages to encapsulate reusable functionality.
