Here's some code I use to cleanup the html before I send it and to
generate an unsubscribe link. I also remove the /assets stuff from my
images since that breaks the images when the web server is restarted.
Html emails tend to hang around longer than web pages.
String cleanupHtml(String s, String url, User user) {
String html = s;
String safeEmail = user.getEmail().replace("@", "\\$0040");
html = regexpReplace(html, "<head>", "<head>\n <BASE HREF=\"" +
url + "\" />");
html = regexpReplace(html, "/assets/ctx/[0-9a-f]+", "");
html = regexpReplace(html, "/assets/[0-9a-f]+/ctx", "");
html = regexpReplace(html, "<SCRIPT.*?>.*?</SCRIPT>", "");
html = regexpReplace(html, "href=\"javascript:[^\"]*\"",
"href='" + url + "'");
html = regexpReplace(html, "href='javascript:[^']*'", "href='"
+ url + "'");
//clear any event handlers like 'onload'
// commented these out because it was messing with meta tags
//html = regexpReplace(html, "on[a-zA-Z]+ *= *\"[^\"]*\"", "");
//html = regexpReplace(html, " on[a-zA-Z]+ *= *'[^']*'", "");
//@import url(elements.css);
//html = regexpReplace(html, "screen.css", "presentation.css");
html = regexpReplace(html, "href=\"/liftyourgame/", "href=\"" +
url);
html = regexpReplace(html, "href=\"\\./", "href=\"" + url);
html = regexpReplace(html, "src=\"\\./", "src=\"" + url);
html = regexpReplace(html, "src=\"/liftyourgame/", "src=\"" + url);
html = regexpReplace(html, "</html>.*", "</html>");
html = regexpReplace(html, "\\[if IE][^\\[]*\\[endif]", "");
html = regexpReplace(html, "</div> <!-- footer -->", "<br/>You
are subscribed as <b>" + user.getEmail() + "</b> <a href='" + url +
"unsubscribe/" + safeEmail + "'>Unsubscribe</a></div> <!-- footer -->");
html = regexpReplace(html, "<!--[^-]*-->", "");
return html;
}
Regards,
Greg.

That's what I do, and it works fine. Make an HTTP request to render
the page and include that HTML in the email. Seems a bit unclean, but
it does work. One does have to be careful about session state, though.
Sending a request from the server to itself will not preserve the
user's session without some extra work.

I would just build a Tapestry page and call it like a web service
from your
email code and put what it returns in the email. It should not be any

complicated than that. If you want it to say
Dear Barry
then make the url /email?dear=Barry
and the tml
Dear ${dear}
