Hey Esa. No. not to my knowledge, but I made a rest client out of the jersey HTTP client which worked, you can get a bare bones bit of starter code here: https://community.jboss.org/thread/152018?start=15&tstart=0
If you read that thread and grab the zip file (on the 2nd page) to get the code you should be able to make your own client / gateway / etc. Good luck!
