The <%@ include %> directive is processed at JSP load time, reading in the
contents of the target file and dropping it inline into the body of the JSP.
(You can't specify this file name dynamically because this would effectively
change the source code of the JSP file, requiring recompilation.)
The <jsp:include/> tag, on the other hand, reads the processed results of
the target URI (i.e. as if you'd requested it from a browser - after
executing any server-side code). You can specify it dynamically:
<jsp:include file="<%= myURIString >" flush="true" />
The results of this request are inserted into the output of the JSP doing
the include (as opposed to the source code of the JSP doing the include).
For this reason, it's feasible to <jsp:include/> all manner of strange
resources, such as CGI scripts.

Subject: Using the include file tag
Does anyone know how to use the <%@ include file="" %> tag with a variable
as
the file name. I need to be able to select the file to include at runtime
and I
thought assigning a variable to the file name would be the easiest way.
Thanks,
Dave
