Subject Re: Start new route after transaction completed
Date Fri, 02 Aug 2013 08:25:01 GMT
Hi

You cannot do this using onCompletion. For 2 different TX in the same
unit of work, you can use the propagation behaviors with REQUIRES_NEW
to start a new TX for the 2nd part.

This use-case is covered in Camel in Action book from page 305 onwards.
