Camel cxfrs with XML

Question

The website that I'm trying to access sends xml only. With Camel's XML DSL I'm trying to get that XML and send it off to another site via cxrfs. For right now I can settle for it going to a bean and merely being able to access the data.

When I execute my route I dont necessarily get any errors. It just doesnt do anything with the XML probably because its not getting stored in the body. Not sure though.

Output

Route

<bean id="proc" class="com.b2bservicep1.httpserv.Proc"/>

<camelContext id="camel" xmlns="http://camel.apache.org/schema/spring">
    <route>
        <from uri="timer://foo?repeatCount=1"/>
       <setHeader headerName="CamelHttpMethod">
            <constant>GET</constant>
        </setHeader>
        <to uri="cxfrs://http://myxmlsitethatimcalling.com?resourceClasses=com.b2bservicep1.httpserv.Proc"/>
        <to uri="bean:proc?method=process"/>
    </route>
</camelContext>

</beans>

Processor that I wrote

package com.b2bservicep1.httpserv;

import javax.ws.rs.GET;

import org.apache.camel.Exchange;
import org.apache.camel.Processor;

public class Proc implements Processor{

    @Override @GET
    public void process(Exchange arg0) throws Exception {
        // TODO Auto-generated method stub
        System.out.println("My Processor! Get In");
        System.out.println(arg0.getIn().getBody());
        System.out.println("My Processor! Get out");
        System.out.println(arg0.getOut());
    }

You need to specify more than just one Method header. Here is an example

@Test
public void testGetCustomerWithCxfRsEndpoint() {
    Exchange exchange 
        = template.send("cxfrs://http://localhost:" + getPort1() + "/" + getClass().getSimpleName() + "/?httpClientAPI=true", new Processor() {
            public void process(Exchange exchange) throws Exception {
                exchange.setPattern(ExchangePattern.InOut);
                Message inMessage = exchange.getIn();
                // set the Http method
                inMessage.setHeader(Exchange.HTTP_METHOD, "GET");
                // set the relative path
                inMessage.setHeader(Exchange.HTTP_PATH, "/customerservice/customers/123");                
                // Specify the response class , cxfrs will use InputStream as the response object type 
                inMessage.setHeader(CxfConstants.CAMEL_CXF_RS_RESPONSE_CLASS, Customer.class);
                // since we use the Get method, so we don't need to set the message body
                inMessage.setBody(null);                
            }
        });

    // get the response message 
    Customer response = (Customer) exchange.getOut().getBody();
    assertNotNull("The response should not be null ", response);
    assertEquals("Get a wrong customer id ", String.valueOf(response.getId()), "123");
    assertEquals("Get a wrong customer name", response.getName(), "John");
    assertEquals("Get a wrong response code", 200, exchange.getOut().getHeader(Exchange.HTTP_RESPONSE_CODE));
}
