Avoid the JSTL SQL tags; they should not be used for any serious application. Using them mixes data access code with the presentation layer, which is considered really bad design.

What Ulf said.


From the JSTL Spec.

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.
