Camel Splitter - XML content

[Robert Thullner <rt...@gmx.at>]

Hi 

I am sending a a JMSTextMessage with XML content to a SM JMS Consumer. Then
the Camel SE should take the message, split it and send it to a JMS
Provider.

My message looks like this:

<document>
   <patient>
    ....
   </patient>
   <paymentInfo>
   ...
   </paymentInfo>
   <history>
   ...
   </history>
</document>

For the splitting I use this camel route:

XPathBuilder splitNurseSystem = new XPathBuilder("/document/*");
from("jbi:endpoint:http://eip.hospital.servicemix/routing/endpoint")
.splitter(splitNurseSystem)
.to("jbi:service:http://eip.hospital.servicemix/doctorService");


When I send a message, I get the following exception:

ERROR - JmsComponent                   - Error processing exchange InOnly[
  id: ID:192.168.2.102-117cb20e17c-4:15
  status: Active
  role: provider
  service: {http://eip.hospital.servicemix}doctorService
  endpoint: enpoint
  in: null

I would think that after the splitting, the content of my messages should
still be XML, so I do not really understand the exception. 

Do I need a custom marshaller or some XSLT transformations to get the
splitter working or is there a simpler way?

Thanks for help
Robert
