Serve files from folder outside web application in Jetty

Question

I have a Java web application (Eclipse/OSGI) on a Jetty server. I want to be able to serve static files to my web application from a folder outside of the web root. In my web application, I don't yet know the file name of the file I want to be served, so I want to take the filename (and/or path) as a VM parameter when I start my web application. For example:

I have an image - myImg.jpg - that I have put in a folder on the server file system, for example root/images/myImg.jpg. I want to take this as a VM parameter, e.g. "-DmyImg=/images/myImg.jpg/" so that I can get the image and display it on my web page. How can I accomplish this? Can I do this without creating a new Servlet?

Thanks in advance for any help!

Solved it!

This is what I added to my jetty.xml file:

<Set name="handler">
    <New id="Handlers" class="org.eclipse.jetty.server.handler.HandlerCollection">
        <Set name="handlers">
            <Array type="org.eclipse.jetty.server.Handler">
                <Item>
                    <New class="org.eclipse.jetty.server.handler.ContextHandler">
                        <Set name="contextPath">/myContextPath</Set>
                        <Set name="handler">
                            <New class="org.eclipse.jetty.server.handler.ResourceHandler">
                                <Set name="directoriesListed">false</Set>
                                <Set name="resourceBase">/actual/folder/on/file/system</Set>
                            </New>
                        </Set>
                    </New>
                </Item>
                [...other handlers...]
            </Array>
        </Set>
    </New>
</Set>
