It seems that you're expecting that image to be served by the default servlet or as a JSF resource since it's on your filesystem. This won't happen unless that imagine is part of your web-app.

In order to serve it, return a StreamedContent object from your method, something like this return new StreamedContent(new FileInputStream(getPathFromDatabase()));. Note that the returned property should be available in session scope or request scope, because the image is served by the Primefaces resource handler in a separate request. This means that if you return the StreamedContent object from a view scoped bean, it won't be available on subsequent requests.

The value attribute of graphicImage is a relative url (or a binary stream if you implement StreamedContent), relative to your context. That means it is appended to the url of your application, resulting in something like: http://hostname:port/appname/relative_image_url.
