If an error is displayed when you access a remote service,
it might be one of these issues.
Resource availability
Click on the link, and make sure that it takes you to the
external application and loads the resource. This allows you to check
that the resource exists or if there is a configuration issue. If
the resource is available, and friendsconfig.rdf is
populated, that points to a configuration issue between applications.
It might be the case that the OAuth key and OAuth secret values stored
in Rational DOORS Web Access do not match the values in
the remote service.
Remote service configuration errors
When Rational DOORS (not Rational DOORS Web
Access) is started it connects to each remote server configured in
the database properties Remote Server tab and
requests each remote server’s rootservices document. If the remote
server is unavailable or the information configured in Rational DOORS is
incorrect, Rational DOORS Web Access displays an error
message when it tries to access the remote resource.
Displaying errors
Remote service errors are usually displayed once only.
Later attempts to access an invalid entry are ignored.
