Ideally i'd have a template directory under WEB-INF where numb-nuts dreamweaver types can edit email templates and i particularly like the expression syntax which is like jsp2. So i was trying to think of a way of using just that.
Velocity would be a really tidy way of doing things if the VelocityEngine class had a getTemplate method that takes in a file rather than just a string. At the moment I've a velocity servlet thats really only there to get around this problem.
But as things are its not that bad i've have just preferred not having to have a velocity servlet running just to find the where abouts of the template.
Using jsp even better as everythings already there, just how to drill to what i need. RequestDispatcher could be an option request the file get its context and then stuff the map in there, but could be tree-barking or/and smoking too much crack.

Mark,
I'd like to know how to do what you're but, unless someone else knows, how
about a different approach:
You could have a "store" tag which gets the body of a tag and stores it
somewhere (in the request or session or in a bean in the request or session)
and then forwards to an email action which then gets the stored content and
sends an email. Something like:
------EmailTemplate.jsp----- <custom:store name="myForm" property="emailContent" scope="session"> ------ format your email here ----- </custom:store> <logic:forward name="emailForward"/>
------- StoreTag.java---------
