Apparently you've just returned an invalid URL to it, or you misunderstood how the image URL is been resolved relative to the URL of the current page.

First, you need to figure the absolute URL of the image. It should be the URL as you see in browser address bar when you would like to obtain the image, for example:

http://localhost:8080/contextname/images/foo.png

If this returns a valid image, then you should make sure that the <h:graphicImage> value ultimately ends up with the same path:

<img src="/contextname/images/foo.png" />

You can achieve this with:

<h:graphicImage value="#{myObj.img}" />

where #{myObj.img} must return the string "images/foo.png".
