Custom tags are user defined tags. They eliminate the possibility of scriptlet tag and separates the business logic from JSP page and makes it reusable.Some examples of tasks that can be performed by custom tags include operating on implicit objects, processing forms, accessing databases and other enterprise services such as email and directories, and implementing flow control. Custom tags increase productivity because they can be reused in more than one application.
