Hi Raul,
Thanks for replying.
But for saving the extracted element, I use a Hashmap.
I just want to extract the element and store it in the Hashmap and not in
the header itself.

Hi Lars,
I would like to get that element, and not to set my header. If i am not
wrong, i cannot use, xpath along with getHeader() expression.

If i use the Xpath java API, something like this:

xpath.compile("substring(string(/*[local-name()='Envelope']/*[local-name()='Header']/*[local-name()='ReplyTo']/*[local-name()='ReferenceParameters']/*[local-name()='ServiceGroupId']/text()),

Hi claus,
How will I add an processor onto the hash map?
Something like this yields me error
map.put(id , getProcessors());
And also My code is as follow:
public void process(Exchange exchange) throws Exception {
Processor target = chooseProcessor(exchange);
Hi claus,
How would i perform xpath evaluation in
exchange.getOut().getHeader("ServiceGroupID", String.class);
I did not find any example where xpath is evaluated in the getheader()
function.

As camel's loadbalance.sticky() just check for the expression in the

Hi Claus
I am extremely sorry, But it doesn't make any sense to perform the path
operation after the loadbalncer? If I perform the xpath after loadbalancer,
does it searches for the expression in the resposne? And if I perform it
after balancer, does it performs sticky load balancing based on the

How can I tell camel to search it in response instead?

I got it working, Thanks for your support and help guys!

I figured it out. Instead of localhost or 0.0.0.0 in the from if I directly
insert the IP address of the local host and remove / after the port number
in URI, everything works fine. :)
So the code would would be something like this
from("jetty://http://192.168.39.204:8080?matchOnUriPrefix=true";)
Yes I tried! But still it didn't work. I am getting this error with the
bridgeEndpoint added in the code.
Any help would be very much appreciated.
