I got this working... thank you to Sergey and Kalyan for your assistance. After following your trails around and learning some more, I found that the main issue was that I had defined the return type for my REST operation as String, so Camel was dutifully converting to that and I did not have a Response to get the code from. After I changed the return type from String to Response, things started working.
If it appears that I've got something confused still, I'm happy to hear about it. -Steve > -----Original Message----- > From: Steve Huston [mailto:shus...@riverace.com] > Sent: Monday, November 02, 2015 6:36 PM > To: users@camel.apache.org > Subject: Re: How to access payload from REST 404 reply in cxfrs? > > Thanks again, Sergey.
