J2EE deployment folders are meant to block access to the filesystem directly because it breaks application portability - so you can't access an images file in a folder outside of your deployment via a URL through the server on purpose. You might be able to create an external empty war deployment, and work it that way but you're still working within a deployable artifact attached to a context. I'd recommend taking a look at something like <a href="http://www.webdav.org/" rel="nofollow">webdav</a> to offload images to an exterior non deployment dependent location. I should mention that jboss 3.2.8 is way out of date - 7 is out and sticking with 3.x... Well - it'd definitely be worth trying your deployment on 7 and seeing what breaks. If you've done it right your deployments should be minimally impacted. Stick as closely as you can to the specs so server upgrades don't break your application.

The closest you can get is a hosted contextual mapping to a local directory as explained in this article: http://community.jboss.org/wiki/ExternalDirectories, but it will only serve up static content, no jsps or dynamically compiled resources. One purpose of the j2ee spec is to formulate some kind of standard so that multiple vendors can deploy a standard enterprise application and you can migrate. If your application uses custom descriptors however, you roll the dice if you ever want to explore the idea of migrating to a different vendor. That's the choice you end up with - either stick to the standards or risk locking yourself into a single vendor's platform. I've been in your situation before, and I've been burned before by it so I tend to lean towards using the standard. Unfortunately there is no direct equivalent in JBoss.

It the connector which does it. But then I dont understand how to achieve this in jBoss. Any thoughts would be very helpful Yes, I think your what you say is correct. It the connector which does it.
