In serviceMix 3.3.1.11 I can't find any example really different from what I
did. There is just a camelContext bean in all examples, with a package, or
routing rules inside like this : 

<camelContext id="camel"
xmlns="http://activemq.apache.org/camel/schema/spring">
	<package>org.bridge.camel.su.MyRouteBuilder</package> 
</camelContext>

I tried to remove jbi component declaration (yes I took it from the
servicemix-camel example of apache) I had on my xml file to match these
examples, but I can't find any service or endpoint declaration example.

I tried but I still don't know how to make routing. I don't understand the
role of the tracker endpoint at 
http://servicemix.apache.org/servicemix-camel.html servicemix camel example 
and why it references a #tracker bean...

So maybe I've misunderstood : to route from a service unit like http to
another using camel I need a registered camel service with an endpoint to
route to from the http consumer, right ? (we can't deploy an http su without
specifying a target service or endpoint). 

I read documentation, I understand the architecture but the implementation
is not clear to me. Can someone give me a small explanation please ? 

Thanks, Florian

Re: Trying to route http msg with camel

Hi Florian,

In order to route from an HTTP-SU, you need to do the following 

    a> in your camel xbean.xml where you have defined a route, you need to
set up a jbi listener endpoint as follows

    <route>
      <from
uri="jbi:endpoint:http://mynamespace/myhttpservicelistener/endpoint"/>
      <to uri="jbi:endpoint:http://mynamespace/mySMXBeanService/endpoint"/>
    </route>

     Alternatively you could choose not use an HTTP-SU at all and do this
directly in the servicemix-camel route as follows

    <route>
      <from uri="http://www.mywebsite.com/myhttpservicename/endpoint"/>
      <to uri="jbi:endpoint:http://mynamespace/mySMXBeanService/endpoint"/>
    </route>

    b> If you choose to use the HTTP SU then point the target service and
target endpoint to the listener you have set up in camel as follows

<http:endpoint service="mynamespace:MyHTTPService"
               endpoint="endpoint"
               role="consumer" 
               targetService="mynamespace:myhttpservicelistener"
               targetEndpoint="endpoint"
              
locationURI="http://www.mywebsite.com/myhttpservicename/endpoint"
               defaultMep="http://www.w3.org/2004/08/wsdl/in-out" />

Hope this helps.

Cheers,

Ashwin...

P.S: If you have prolonged trouble with this please email me at
askarpe@progress.com and I will mail you a working example that may not
exactly the thing you are looking for but pretty close.
