Which Java templating system should I use to generate emails?



I have a website that uses JSP as its view technology (and Spring MVC underneath). Unfortunately, JSP is just a pain to use for anything that doesn't involve an HTTP session. I would like to be able to occasionally send my users some email, and I want to use something JSP-like to render the email's contents. Technologies I'm aware of include:

  • JSP -- It can be forced to work for this sort of thing, I think. Very worst case, I could request the page from my own webserver and render that into an email (ugh!)
  • Velocity -- I've heard good things about this one, and am leaning towards it.
  • StringTemplate -- Looks okay, but I'm worried that no new releases have come out in a year.

Is there a preferred technology for templating in a Java system? Would folks generally recommend Velocity? Is there a good way to use JSP for more generic tasks?

I used Freemarker a lot for e-mail templating and it worked great and was easy to use..

I have used StringTemplate several times successfully for sending emails.

It is simple and extremely easy to integrate.. The simplicity of StringTemplate makes it straightforward to substitute different parts of the message, for example, subject.

Not sure how to do this with Velocity.. I wouldn't worry about the release frequency -- maybe it is just good enough and doesn't need to be actively developed any more..
