Hi Wilson

The first error is caused by the Exchange that you get from activeMQQueue misses the CXF message which is came from cxfRouter.

My question why do you want to put the router message into the activeMQQueue and then put it to the cxfService endpoint. If you want the request to be put into the activeMQQueue, you could write your router configuration like this.

--------JAVA CODE--BEGIN-------------
 from(cxfRouter).multicast(new UseLatestAggregationStrategy())
 .to(activeMQQueue, cxfService);
--------JAVA CODE--END-------------

Hope this will help you :)

Hi Willem,

I've got the last 1.3 SPAPSHOT and the problem is gone.

Now I have another one.
It is possible to do this?

--------JAVA CODE--BEGIN-------------
  from(cxfRouter).to(activeMQQueue);
  from(activeMQQueue).to(cxfService);
--------JAVA CODE--END-------------

When I try this configuration, I got this exception:

If I try this route:
--------JAVA CODE--BEGIN-------------
  from(cxfRouter).to(activeMQQueue).to(cxfService);
--------JAVA CODE--END-------------

The external client is called but the message is note dequeued from the JMS
queue.

Thank you,

Hi Wilson,

I just traced the code and find a way to fix this issue and it will be in the trunk soon :)

Yes , it must be a camel-cxf component's bug. Could you fill a JIRA[1] for it ?

Hi,

I found a workaround for the problem. I added a processor after the CXF
router endpoint:

-------JAVA-CODE--BEGIN-------------------------------------------
        String anyEndpoint = "activemq:pedidos";
        
        from(StringUtils.join(cxfRouterURI)).process(new Processor(){
                        public void process(Exchange exchange) throws Exception 
{
                                exchange.setOut(exchange.getIn());
                        }
        }).to(anyEndpoint).to(StringUtils.join(cxfServiceURI));
-------JAVA-CODE--END-------------------------------------------

Now it is working.

I think there is a bug in CXF Camel code.

Hi Willem,

I am using Camel 1.3. I am using Maven to build the project. Today I
updated to the snapshot released on 2008-01-09 but the problem is
still
there.

Thank you.

Hi Wilson,

Which version of Camel are you using?
Please try out Camel 1.3 snapshot which fixed a camel-cxf component's issue which can't pass the exchange back form the cxf producer.

Hi Willem,

Thank you for your reply!

I changed my code in order to use a SEI to describe the Web Service.
Now
it
is working fine but I am having problems when I add an endpoint
between
the
cxf endpoints.

The (working) code looks like this:

--------------------------------------------------------
package com.tc.eai;

import org.apache.camel.builder.RouteBuilder;
import org.apache.camel.spring.Main;
import org.apache.commons.lang.StringUtils;

public class MyRouteBuilder extends RouteBuilder {

        private static String ROUTER_ADDRESS =
"http://localhost:9003/pedidoService";;
        private static String DATA_FORMAT = "dataFormat=MESSAGE";
        private static String SERVICE_NAME =
"serviceName=%7bhttp://www.tc.com/pedido%7dpedido";;
        private static String SERVICE_CLASS =
"serviceClass=com.tc.eai.PedidoService";
        private static String PORT_NAME =
"portName=%7bhttp://www.tc.com/pedido%7dpedidoSOAP";;
        private static String SERVICE_ADDRESS =
"http://localhost:9000/pedidoService";;
        
    /**
     * A main() so we can easily run these routing rules in our IDE
     */
    public static void main(String... args) {
        Main.main(args);
    }

    /**
     * Lets configure the Camel routing rules using Java code...
     */
    public void configure() {
        //-- Router receives requests from external clients and send to
channel
        String[] cxfRouterURI = {
                "cxf://"
                ,ROUTER_ADDRESS
                ,"?"
                ,DATA_FORMAT
                ,"&"
                ,SERVICE_NAME
                ,"&"
                ,SERVICE_CLASS
                ,"&"
                ,PORT_NAME
        };

        //-- Service points to external web service. The request routed
by
the
Router //-- is send to the external service provider
        String[] cxfServiceURI = {
                "cxf://"
                ,SERVICE_ADDRESS
                ,"?"
                ,DATA_FORMAT
                ,"&"
                ,SERVICE_NAME
                ,"&"
                ,SERVICE_CLASS
                ,"&"
                ,PORT_NAME
        };

from(StringUtils.join(cxfRouterURI)).to(StringUtils.join(cxfServiceURI));
    }
}
--------------------------------------------------------

When change the route this way:

        String anyEndpoint = "log:org.apache.camel?level=DEBUG";
        
from(StringUtils.join(cxfRouterURI)).to(anyEndpoint).to(StringUtils.join(cxfServiceURI));

I get this error:

The same problem happens with seda and activemq endpoints.

Thank you,

Hi Wilson,

I am afraid you need to provide the SEI  class for camel-cxf
component to initiate the endpoint.
If you do not want to unmarshal the request message , I think you
could use soap message or raw message data formate. Now I am thinking to do some refactoring work to enable the web services endpoint without SEI class.

Willem.
