Hi. I don't know is it really what you need. but you can try it anyway.
Edit file jboss-service.xml, which is located in $JBOSS_HOME/server/default/deploy/jbossweb-jetty.sar/META-INF by additing something like this:
Check that you point right you webdefault.xml.
It will create default web context for in directory which is specified in second block. That directory should include WEB-INF dir with some empty web.xml - it might works without WEB-INF i never try :=)
Then put index.html and redirect webflow to some else like error page. Obs! jsp is not supported !
Has anyone figured out how to get JSPs to work with the addWebApplication call in jboss-service.xml for Jetty?
You'd have to experiment with the following remedy as I have only examined possible configuration with an external context. I'll probably get around to a full tech note in the next couple of days but it doesn't seem too flexible.
