Thanks for getting back so quick.
It wasn't the space, I removed it
and still got the same error so
I guess it must be how resin
looks for the files.
By the way, my class is located in
the WEB-INF/classes directory if that helps.

I have not used the resin server so there may be issues with that as we
have found inconsistencies between scanning techniques on different web
containers. But see below... it looks like you have a additional space
character for the package name.

Is that a space character?
What happens if you delete the space character?
If that solves things it is a bug in Jersey, it should call
String.trim(). Plus we should have logging for packages that are not
found.
