Adding to the fine responses you've already received:

The build-time include is useful for sharing a JSP fragment amongst
several full JSPs.  If you use a full-blown layout system such as Tiles,
this is moot; but for a more homegrown setup, <%@ include%> is a nice
approximation.

Two notes if you go this route:
1/ name your JSP fragments something other than ".jsp" (".jspf" is the
unofficial standard) such that they aren't picked up by a precompiler

2/ watch those file sizes.  Overusing the build-time include can fatten
up the resultant .java file to the point it doesn't compile.  (or was
that the JSP itself gets too big to be translated to Java source?
Either way, it's ugly.)
