How to call ws endpoint from LoanBroker

Hi,

I'm learning ServiceMix and JBI and would like to modify the ESB LoanBroker
example to call 
one of the web services configured in the cxf-wsdl-first example.  I've
looked around but
can't find an explanation of how to reference the web-service endpoint. Can
someone point
me in the right direction?

Thanks, Garry

Hi Garry,
Let's me explain how the client proxy configuration per as blow works

<cxfse:endpoint>
        <cxfse:pojo>
          <bean 
class="org.apache.servicemix.cxfse.GreeterImplForClientProxy" 
autowire="false">
              <property name="calculator">
                  <cxfse:proxy service="calculator:CalculatorService" 
context="#context" type="org.apache.cxf.calculator.CalculatorPortType" />
              </property>
          </bean>
        </cxfse:pojo>
      </cxfse:endpoint>

this snippet shows that a pojo GreeterImplForClientProxy has a property 
calculator (as type org.apache.cxf.calculator.CalculatorPortType) , 
which is a client proxy of another cxf endpoint (I believe here "client 
proxy of another cxf endpoint" == "CXF endpoint reference" in your 
mail),  so you can invoke another cxf endpoint from pojo 
GreeterImplForClientProxy.
[1] is the code for GreeterImplForClientProxy. Also, in this class you 
can see servicemix ComponentContext is also injected in, so that you can 
get ServicemixClient by means of
ServiceMixClient client = new ServiceMixClientFacade(this.context);

Yeah, you can configure this pojo's client proxy(reference) in another 
cxf endpoint as I show you how

I don't think you need write these code your self, since client proxy

Since we support inject context into pojo as I show, you can create a 
ServicemixClient from the context if you really want. But from the code 
shows in GreeterImplForClientProxy, you can see it's very easy to invoke 
another endpoint inside pojo without ServicemixClient.

Re: How to call ws endpoint from LoanBroker

Hi Freeman,

My CXF service is configured as below, which looks
about like what you show in your message:

  <beans xmlns:cxfse="http://servicemix.apache.org/cxfse/1.0">

      <cxfse:endpoint>
          <cxfse:pojo>
            <bean
class="org.apache.servicemix.samples.cxf_wsdl_first.PersonImpl" />
          </cxfse:pojo>
      </cxfse:endpoint>

  </beans>

My CXF service deploys just fine and for testing 
purposes, I can invoke it via simple JavaScript. Of
course, what I'm really trying to do is invoke my CXF
service from a POJO deployed to the lightweight container
(servicemix-lwcontainer).  From the code snippet you kindly
sent me (CxfSeClientProxyTest.java), I gather I should do
something like this inside my POJO:

  client = new DefaultServiceMixClient(container);
  io = client.createInOutExchange();
  io.setService(new QName("http://apache.org/hello_world_soap_http",
"SOAPService"));
  io.setInterfaceName(new QName("http://apache.org/hello_world_soap_http",
"Greeter"));
  io.setOperation(new QName("http://apache.org/hello_world_soap_http",
"greetMe"));

Have I got it right? If so, a couple more questions:

My POJO looks like this:

  public class LoanBroker extends ComponentSupport implements
MessageExchangeListener

and I'm having a hard time figuring out how to create
a ServiceMixClient. I can't seem to get a JBI container
reference and so the technique in your example won't work.
Obviously, I'm still learning the API; how can I create a
ServiceMixClient from a POJO extending ComponentSupport?

While I intend to explore the ServiceMixClient approach,
I'm wondering if I can't simply configure a CXF endpoint
declaratively in my lightweight container configuration file
(servicemix.xml) and inject it into my POJO.  Is the  
"programmatic" ServiceMixClient approach the only way to
go or can I configure a CXF endpoint reference? (Got an 
example for that?)

Thanks again, Garry

Re: How to call ws endpoint from LoanBroker

Posted by Freeman Fang <fr...@gmail.com>.

Hi Garry,

If you want to reference cxf web-service inside jbi container, you can 
see how client proxy is used inside cxf-se.
the configuration is per as below

      <cxfse:endpoint>
        <cxfse:pojo>
          <bean 
class="org.apache.servicemix.cxfse.GreeterImplForClientProxy" 
autowire="false">
              <property name="calculator">
                  <cxfse:proxy service="calculator:CalculatorService" 
context="#context" type="org.apache.cxf.calculator.CalculatorPortType" />
              </property>
          </bean>
        </cxfse:pojo>
      </cxfse:endpoint>

And [1] is a test to illustrate how client proxy is used
