Just as a note, if you are interested in running on AS7, you may want to take a look at :http://community.jboss.org/blogs/mariusb/2011/07/13/spring-and-jboss-as7-part-1-getting-started.
This covers the very basics for now, and if course, more complex applications may have their own specific issues, so Red5 may have its own special settings. If you can post an article in the Articles documenting what you did, it would be great!
Thanks,
Marius
