In a j2ee tutorial I have seen the paths to the action attribute of a form have been specified by retrieving from pageContext implicit variable like below

<form action="${pageContext.request.contextPath}/orderForm" method=post>

Is it a best practice to do so?

I think it is.
Even if the application's root changes, your links won't be broken.
Waiting for some experts to bring light on that

Of course it is. Otherwise the path gets hard-coded everywhere. How fragile.
