I just want to include an HTML file server-side into another HTML file, using JSP. PHP is not available. Is this what I want?
<jsp:include page="/include.html"></jsp:include>

A:
You have a couple of options. The first is <jsp:include>. The second is <c:import>. The c: tags are JSTL, the JavaServer Pages Standard Tag Library.
What's the difference? Primarily <jsp:include> inserts the contents of another JSP page within the same JAR relative to the current page whereas <c:import> can read in an absolute or relative URL and display those contents on the page, retrieve a Reader or store the contents in a variable.
The syntax for both is XML-like so:
<jsp:include page="header.jsp"/>
or
<jsp:include page="header.jsp"></jsp:include>
Note: both can take parameters.

+1. Looking at the docs, it does appear that <jsp:include> will do what the OP is asking for; however, it does not appear to be completely analogous to PHP's include(). Notably, the included file does not share the same global scope; functions/classes created by the included file won't become available in the including script, etc. Instead, it executes the included script, and returns the output.

Where's your vote, Frank? I did the first upvote, but I don't see a second one :)

Thanks, so the example I have above is the proper syntax?

@devils-avacado: yes. @cletus' edit: the actual difference between `jsp:include` and `c:import` is that the first includes the *source* and that the second includes the *output* (apart from having the possiblity to get it from an external URL).

@cletus or @BalucC, can I include .html, .shtml, .js, or .css using either method? Excuse my ignorance, I'm completely new to JSP.

The included document is arbitrary so it could be CSS, Javascript or HTML ie what you could normally have in an HTML document.
