Which was one thing I had already done - didn't use comments, but did
all my up-front work in one line.

For the paranoid, you probably want to be sure that the email
template

Because you're
doing an include followed by a forward, there's a *possibility* that
the
forward will throw an IllegalStateException if the include causes the
response
to be committed. You can use one of the various JSP whitespace
"hacks" to
help:
<%@ taglib uri="http://struts.apache.org/tags-bean"; prefix="bean"
%><%--
--%><bean:define id="emailStuff" toScope="request">
...
</bean:define>
Obviously, the example is unlikely to cause a problem, but a more
involved page
might.
Another approach might be to pass an HttpServletResponseWrapper to
the include
method whose output stream (or writer) just buffers the entire
response for
later retrieval.
Quoting Niall Pemberton <[EMAIL PROTECTED]>:
You can do this easily using the <bean:define> tag and the
RequestDispatcher. I've put a page up on my web site showing how:
http://www.niallp.pwp.blueyonder.co.uk/emailTemplate.html
I believe the RequestDispatcher is the "magic" JSP processor you're
looking
for.
