Subject AW: AW: AW: Problem with SOAP/JMS and transactions
Date Mon, 02 Nov 2009 15:19:27 GMT
Hi Willem,

thanks for the help. I can not compile camel at work - will try this from
home later. If it works I could even get it into our local distribution
quickly as I had to build a custom version of camel-cxf anyway because of
the annotation issue.

Greetings

Christian

Hi Christian,

I'm glade it works on camel side.
For the CXF side , I think we need to check the CXF message's exception 
in the Camel transport and let camel throw the exception.

Here is my patch on the latest trunk code (not be verified yet), please 
feel free to give it a try.

### Eclipse Workspace Patch 1.0
