Discover how to connect a JSP website to a database and allow end-users to perform database operations from the web UI using this course. Learn how to set up a MySQL database, use JDBC to connect to and run queries against this database, and utilize the JSTL library in order to iterate over the data that is returned and render them on your web page. You'll also explore write operations, JSP action tags like useBean and setProperty, and implementing update and delete operations on the database. After finishing this course, you'll have the skills and knowledge to allow users of a JSP website to interact with a database.
