This week's book giveaway is in the General Computing forum. We're giving away four copies of Arduino in Action and have Martin Evans, Joshua Noble, and Jordan Hochenbaum on-line! See this thread for details.
Many web applications need to access relational databases as the source of dynamic data for their presentation layer. While it is generally preferred to have database operations handled within the business logic of a web application designed with an MVC architecture, there are situations where page authors require this capability within their JSP pages (e.g. prototyping/testing, small scale/simple applications, lack of developer resources). The JSTL SQL actions provide the basic capabilities to easily interact with relational databases.
