Hi,

You can set the request context on the message to workaround this issue.
Here is an example from camel-cxf unit test[1] that you can take a look.

I did take a look at the sources and I think I found the
root of my problem, though I'm not sure how to get around it:

RecipientList class contains a producer cache,
in this cache the RecipientListProcessor class does store the
endpoints depending on the uri as key.
Now since only my header changes I don't know how to get around this.
Any ideas?

Thanks in advance, Achim

Ok,

some more worrying details.

Right now I have two Remote Hosts
After a successful run on Host A a second run is done (not parallel
but sequential) on Host B.
And I'm able to see that the header.address is set to host B still I
see that the request is made on Host A.

Is this intentional, are there any ways of not "remembering" which
call did go to which Host?

Thanks again, Achim

Hi

using Camel 2.8.0 I'm having the following scenario.
I'm using the CXF for connecting to a couple .NET Webservices.

        <!-- CXF config -->
        <cxf:cxfEndpoint id="productionServer"
                
serviceClass="net.testservices.productionservice._2011_07.IService"
                endpointName="s:basicHttpProductionService" 
serviceName="s:ProductionService"
                wsdlURL="classpath:/wsdl/_1.wsdl" xmlns:s="http://tempuri.org/";
                
xmlns:a="http://schemas.microsoft.com/2003/10/Serialization/Arrays";
                xmlns:i="http://www.w3.org/2001/XMLSchema-instance";>
                <cxf:properties>
                        <entry key="dataFormat" value="POJO" />
                </cxf:properties>
                <cxf:outInterceptors>
                        <ref bean="loggingOutInterceptor" />
                </cxf:outInterceptors>
        </cxf:cxfEndpoint>


Now I have a route for looking up some data in the DB for example also
looking for a free
WebService to call:

                <camel:route id="pollQueue">
                        <camel:from 
uri="timer://pollQueueTimer?fixedRate=true&amp;period=30000" />

... do preparation ....
... also set the address of the remote host into the header of the exchange ...
... call the "production" route ...

                                        <camel:to uri="seda:production" />
                </camel:route>

the production route does call the Webservice on the available remote
host as follows

... again a couple of preparations beforehand ....

                        <!-- Altering Body to contain no data -->
                        <camel:setBody>
                                <camel:mvel>[ ]</camel:mvel>
                        </camel:setBody>

                        <!-- service call -->
                        <camel:setHeader headerName="operationName">
                                <camel:constant>ProduceData</camel:constant>
                        </camel:setHeader>

... the address of the remote webservice was previously added to the
header in the starting route ...


... I needed to set the parallelProcessing to true, if not everything
fails because the Timer Route tries to start another recipientList ...

                        <camel:recipientList parallelProcessing="true">
                                
<camel:simple>cxf:bean:productionServer?address=${header.address}</camel:simple>
                        </camel:recipientList>

... some more calls checking data, errorhandling  and so forth ....


Now the following happened to me when I had more than one Remote Host
available:

Calls to Host A did run on Host B
Results expecting to be retrieved from Host A where polled from Host B.
Now I wonder if the calls to certain Methods are cached or if the
"re-running" timmer route does
interfere somehow with the already running route.

A Complete run of a route can take up to about 30 Minutes after that
the "Production"-Route is done.
Since there are multiple hosts available we want to do parallel processing.

Any hints are welcome,

Achim
