are you sure that the value attribute points to the resource ? Is your rf.png in the root of the deployed .war ? Are you not getting 404 error on Chrome console ? Otherwise it has to work.
Doc for h:graphicImage
Docs for <rich:panel>
thanks for the links, i checked the docs on it, seems to be right.
the .png file is in the same folder my xhtml. that´s why there is no long path. Me and a friend here tried some things and seems like the graphic tag is not generating the proper img tag. The output i meant before is a <h:graphic tag. I ´ll look into that.
It worked, finally.
The problem was with rich configuration itself, not just the tag. The tag panel also was not working.
I just put an index.html for initial page and linked an xhml and made the propper changes in the web.xml.
Now the right html output is generated.
