Re: Conflict between aries-jax-rs-whiteboard and pax-web jetty handler

[Nhut Thai Le]

Thank you for your suggestion, however, that approach binds a patterns to
one resource location only. I have few bundles, each have an icons folders
that need to be served with the same pattern /icons/*. The reason for this
is that the url to the static resources (icons) are dynamically generated
and the generator does not know in advance which bundle should provides the
icon so it just generated something like "http://mysite.com/icons/car.png";.
