+  * Jasper translates a JSP page to a servlet upon receiving the first reference to it (typically from a servlet forward).
+  * Jasper allows us to embed three things in the JSP page in addition to template (e.g. HTML) code: Expression Language EL, Directives, and Actions. These will be evaluated by Jasper and their values are served as part of the response.

+  * Actions are either standard (JSTL) or custom.
 ===== To Do =====
   * Read the rest of Chapter 6.
-  * Do Lab 4.
