OK. Thanks for the advice. I tried to use Tiles2 because my user interface is
used with Tiles2. If I get a Tile for the email, the email received has the
same look&feel as the web pages. And I can re-use JSP/JSTL/OGNL parts.
I'll give FreeMarker a try... just a question... in the code you sent... the
"String template" argument is just the file name of the Freemarket content
(mail.ftl) file?
Thanks,
Ignacio
