Jakarta Standard Tag Library (JSTL) is a collection of custom tags for JavaServer Pages (JSP) that encapsulate core functionalities common in JSP applications. It simplifies the development of dynamic web pages by providing tags for tasks such as iteration, conditionals, XML manipulation, internationalization, and database access, reducing the need for scriptlets and Java code within JSP files.

A Jakarta Standard Tag Library expert must have strong knowledge of JSP, proficiency in JSTL tag libraries, and experience with Java EE. They should also be skilled in XML and JSON processing, familiar with SQL for database interactions, and capable of integrating JSTL with other web technologies like Servlets and JavaBeans.
