wrong, i cannot use, xpath along with getHeader() expression.

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 claus,
If i use the Xpath java API, something like this:
XPathExpression expression =
xpath.compile(substring(string(/*[local-name()='Envelope']/*[local-name()='Header']/*[local-name()='ReplyTo']/*[local-name()='ReferenceParameters']/*[local-name()='ServiceGroupId']/text()),
10));
String id =
Hi,
I wanted to extract a term from my soap message, I tried using Xpath but, no
matter what I try i always use to get an error: Invalid xpath expression. So
i decided to take help of CXF.
I came up with something like this:

Hi claus,
Thanks for replying.
But why do i always get an error invalid xpath expression, when the same
xpath expression works fine with java API.
I also tried the java API version and again i got an error saying the body
is empty.
And in real the body is empty, because the content are present
Hi claus,
How can I evaluate xpath in both process method and getProcessor method?
I did something like:
Processor target = chooseProcessor(exchange);
XPathBuilder sessionID =
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.

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:

Hi,
I want to perform a sticky based load balancing based on the SOAP session ID
in the response.
As camel's loadbalance.sticky() just check for the expression in the
request, I have to implement my own custom load balancer.
I gave a look at camel in action book and the information provided in
Hi claus,
Thanks a ton for replying.
1) try to get the session id from the soap header (would not be there
on the initial call) : How should I tell camel to skip the initial call and
do not search for session id in the first request?

Hi claus,
I tried implementing your logic and it is as follow:

Hi claus,
Thanks a lot for replying.
I implemented the idea directed by you(I really appreciate that )
But due to some reason my requests are not being forwarded, camel is
continuously retrying.
Here is my code for custom load balancer:

How can I search for an Xpath expression in the SOAP response?
from(something).loadbalnce.sticky(expression).to(something) searches
for the expression in the SOAP request and doesn't checks for the expression
in the SOAP response.
How can I tell camel to search it in response instead?

Hi Claus,
Yes It was also posted by me. In that case I will delete this thread. I
didn't knew you replied on that thread of mine.

I got it working, Thanks for your support and help guys!
The code is as follow:

Hi I would like to perform sticky load balncing in apache camel based on the
SOAP session, whcih is embedded in ServiceGroupID node of the first
response.
I wrote a small route as follow:
from(uri)
.loadBalance().sticky(xpath(query).namespaces(env).namespaces(wsa).namespaces(ax))
.to(BE1,BE2);
Hi,
I just created a small java program just to check if my xpath provides me
with the appropriate infromation that I want(i.e the ServiceGroup ID) And I
go the output as
urn:uuid:99A029EBBC70DBEB221347349722532, the term after urn:uuid: is the
session Id.
So are the terms urn:uuid: culprit?
Is substring supported in camel by the way?
some thing like this
xpath.compile(substring(string(/*[local-name()='Envelope']/*[local-name()='Header']/*[local-name()='ReplyTo']/*[local-name()='ReferenceParameters']/*[local-name()='ServiceGroupId']/text()),
10));

Hello Willem,
Thanks a ton for replying.
My requests are SOAP messages and the seesion ID in AXIS2 are stored in
ServiceGroupID node of the SOAP header. How can I extract this Session ID
and use sticky session? is there any example that would help me understand
this? any help would be really
Hi Willem, My SOAP sessions are embedded in the SOAP header and my SOAP
header looks like this:
?xml version=1.0 encoding=http://schemas.xmlsoap.org/soap/envelope/;
standalone=no?

soapenv:Header
Hi Willem,
I am new to everything that on working on, And these things are still
confusing me. Could you please explain them in more simpler term?
As far I got to know, I have to get my request into camel-cxf endpoint in
PAYLOAD data format and have to extract the header, then I have to use
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;)
Dear memebers,
This would be my first post in this forum and I am glad. I have started
using camel a while back for a project of mine to create a load balancing
application.
Well to start with,
My load balncer would listen to a port, lets say 8080 and would balance all
the incoming SOAP requests
Thanks for replying. But I even tried using 0.0.0.0. Still my problem is not
resolved.

Thanks for replying. Yeah when I input http://172.28.39.138:8080/ in my
browser, apache tomcat page opens. As it is a backend server, and it runs
tomcat in it which is listening on the port 8080 for requests.
I am still struck in this part. Am I doing something wrong?
Any help would be very much
Thanks for replying. I changed from(jetty://http://localhost:8080/;) in my

Any help would be very much appreciated.
