So far, you’ve seen five different types of elements that can appear in a JSP: scriptlets, directives, declarations, Java expressions, and EL expressions.
But we haven’t seen actions. They come in two flavors: standard and...not.
<jsp:include page="wickedFooter.jsp" />
For now, don’t worry about what these do or how they work, just recognize an action when you see the syntax in a JSP. Later, we’ll go into the details.
<c:set var="rate" value="32" />
Although that’s misleading, because there are some actions that aren’t considered standard actions, but which are still part of a now-standard library. In other words, you’ll later learn that some of the non-standard (the objectives refer to them as custom) actions are... standard, but yet they still aren’t considered “standard actions”. Yes, that’s right—they’re standardized non-standard custom actions. Doesn’t that just clear it right up for you?
In a later chapter when we get to “using tags”, we’ll have a slightly richer vocabulary with which to talk about this in more detail, so relax. For now, all we care about is recognizing an action when you see it in a JSP!
