CXFRS consumers - is there a better way?

Hi there,

I've been using the Camel CXFRS component and I have to say that I've found
the learning curve steep. Perhaps this is due to not being familliar with
CXF. Regardless, given my high level of familiarity with Camel and general
experience, implementing a RESTful JSON endpoint was just too hard.

My expectation is that I could express a route for consuming CXFRS requests
using something like this:

from("jetty:http://localhost/").to("cxfrs:consumer?services=#myService1,#myService2");

where my service instances ("#myService1" etc.) are JAX-RS annotated
instances configured in my Spring XML.

All that I want CXF to do is marshall RESTful exchanges into JAX-RS
invocations of beans as I think that this is a good separation of concerns.
Is this possible somehow?

Kidn regards,
Christoppher

Hi Willem,

Just a FYI, I've resolved this issue and provided a patch on the JIRA issue.
Let me know if you think it warrants a test case as I found it pretty
trivial to implement.

Kind regards,
Christopher

Hi Willem,

Thanks for the response. I've now raised a JIRA at 
https://issues.apache.org/activemq/browse/CAMEL-3117

Current cxfbeans doesn't support to configure the provider as you do in the
cxf:rsServer.
I think we can introduce some kind of spring configuration to it.
Please feel free to create a JIRA for it.

OK, previously I specified a provider in the providers element of a
cxf:rsServer element. How do I now specify a provider when using cxfbean? 

This is what I had when using cxfrs:


  &lt;cxf:rsServer id="rsServer"
   
address="http://localhost:${com.classactionpl.gpstrackerservices.httpPort}"
   
serviceClass="com.classactionpl.gpsTrackerReference.GPSTrackerCollectionService"
    staticSubresourceResolution="true"&gt;
    &lt;cxf:providers&gt;
      &lt;bean
       
class="com.classactionpl.gpsTrackerReference.GPSTrackerCollectionProvider"&gt;
        &lt;property name="gpsTrackerCollectionTransformer"
ref="gpsTrackerCollectionTransformer" /&gt;
      &lt;/bean&gt;
    &lt;/cxf:providers&gt;
  &lt;/cxf:rsServer&gt;


...so now that I have the following route declaration, how do I specify the
provider?


  from("jetty:http://localhost:" + httpPort + "?matchOnUriPrefix=true")
        .to("seda:gpsTrackerCollectionWebService");

  from("seda:gpsTrackerCollectionWebService?concurrentConsumers=2").to(
        "cxfbean:gpsTrackerCollectionWebService");


Thanks for your help. I shall update the wiki with the solution you provide.

Kind regards,
Christopher

Gosh, how did I miss that... I've now updated the non-bean CXF pages of the
Wiki to emphasise the benefits of using the bean component with a short note
at the top of each page.

Hi,

You can take a look at cxfbeans[1], it does the exact thing that you 
want to do.
