DefaultServlet cannot (currently) be targeted at a directory other than the root of the webapp. You could probably subclass DefaultServlet and modify its behavior such that you could re-target it to another directory using init-param elements or something like that. It looks like the init() method of DefaultServlet grabs a ProxyDirContext from the application scope. I'm guessing that's a JNDI context that is rooted in the current application's webapp root. By overriding init() (make sure you call super.init()!), you could probably re-target the "resources" member to another directory, and simply leave everything else alone.

For example, place the following in conf/Catalina/[host]/ourshare.xml: You can then forward or redirect references to the images to "/ourshare/[image].gif" and the DefaultServlet will handle them properly. - Chuck THIS COMMUNICATION MAY CONTAIN CONFIDENTIAL AND/OR OTHERWISE PROPRIETARY MATERIAL and is thus for use only by the intended recipient.

Chuck, This a great idea. Now I am trying for find where to put ourshare.xml file. We are using Tomcat under Jboss, I didn't find conf\Catalina yet. Thanks a lot!

Re: Using DefaultServlet for directory outside of webapps
You could write a simple servlet to serve up these images from any accessible file system. The URL for it would look something like this: http://yourtomcatserver/yourwebappcontext/getImage?name=Foo.gif The the servlet would know what directory to look for images in and handle streaming them out to the client. That would be a very flexible way of solving the problem.
