A few years ago, JSTL introduced the concept of EL (Expression Language) to the Java standards. Since then, the technology have been slowing climbing the JCP ladder, first becoming part of JSP 2.0, then having its own API (javax.el). Although there is a lot of documentation out there on how to use EL in places that support it (like the aforementioned JSTL and JSP technologies), there is a lack of resources on how to support EL on *your* application.
