Hi all, I have managed to create two sample OAuth aplications: ordinary OAuth 1.0a client: http://www.oauthclient.appspot.com and authorization server that uses CXF OAuth module: http://www.cxfoauthserver.appspot.com
Both sample applications and changes in oauth library are commited in sandbox. OAuth configuration in sample authorization server app looks a bit awfully but I think most of that can be hidden and done out of band. There is still some areas in specification not covered by implementation, so I would like to take care of that in next steps. Thanks in advance for some feedback. Cheers, Lukasz
