The WADL produced by Jersey is a form of hypermedia. The WADL
describes capabilities of a resource and the relationships to other
resources. The information is derived via Java reflection from the
resource classes at runtime.
Such WADL has been used by JavaScript clients to dynamically create
test web pages e.g. NetBeans can do this. It all works fine as per the
REST style.
Tighter coupling can occur if a client decides to generate static code
from the WADL. That is something i discourage, but can see why some
developers might want to do that but they should be aware of the
technical restrictions that may ensue.
