Hi,
In Glassfissh, the application client container publishes applications via Java Web Start. I looked into the wiki, forum and JIRA and no found related information about such a feature in JBoss.
I know that I could have the same behaviour in building a war archive which embed the application and a servlet to publish the app but, in Glassfish it's already done ;o)
Let me know whether this feature have been planned or if you've got some interesting pointers and resources to speed up the dev.
Thanks.
