Does Struts 2 have support for (or plans for supporting) either Comet processing or HTML5 WebSockets. Googling suggests that the answer for Comet may be no, but the latest page I've found that states this, is from 2008!
Having read the link, I didn't suppose that you were. In this day and age, I am reluctant to put any personal identifiers into an on-line forum, however well intentioned the forum may be. Having said that I fully appreciate that it's "your" forum and your rules, so I'll just say thanks for all the help that you've provided to date and goodbye.
