Re: Need Help: How to configure CXF Client use a CommonsHttpClientTransportFactory

Tue, 29 Jul 2008 05:34:58 -0700
Right. That would do it. Since Jetty subclasses the same stuff as the ClientOnly stuff, it would also replace the client only stuff with it's version.

Hi Dan,

It seems that I just need change my cxf-extension-commons-http.xml
to depends on "JettyHTTPTransportFactory" instead and my simple
CommonsHTTPClientConduit prototype was called finally. It would be

great that you can confirm that is the right way to inject HTTP  
Conduit

into CXF Client.

Thanks a lot for your help!

Hi Dan,

I just went to some code debugging, it seems like that:
AbstractConduitSelector.getSelectedConduit(), which is called by

UpfrontConduitSelector.selectConduit(), returns  
JettyHTTPTransportFactory
for "http://schemas.xmlsoap.org/soap/http";, it'll initiate  
HTTPConduit,



I just quickly searched cxf configuration file, I'm not sure that  
the

following configuration in bus-extensions.xml in cxf-2.1.1.jar is
related to this:
==================================================

<extension  
class 
="org.apache.cxf.transport.http_jetty.JettyHTTPTransportFactory"

deferred="true">
  <namespace>http://schemas.xmlsoap.org/wsdl/soap/http</namespace>

  <namespace>http://cxf.apache.org/transports/http/configuration</

  <namespace>http://cxf.apache.org/bindings/xformat</namespace>
</extension>
==================================================

Any suggestion or tip to resolve this would be really appreciated.

Thanks a lot for your help!

Hi Dan,


The ClientOnly factory should register first (since you depend  
on it), then yours
should get called and register.   (You have a @PostConstruct  
method, right?)


The following is my code snippet for PostConstruct:
=============================================================
@PostConstruct
public void registerWithBindingManager() {
  // ...
  ConduitInitiatorManager cim =
bus.getExtension(ConduitInitiatorManager.class);
  if (null != cim && null != activationNamespaces) {
    for (String ns : activationNamespaces) {
      try {
        ConduitInitiator initor = cim.getConduitInitiator( ns );
        if ( initor != null ) {

         System.out.println( "For " + ns + ", " +  
initor.getClass().getName() );

         cim.deregisterConduitInitiator( ns );
        } else {
         System.out.println( "For " + ns + ", null" );
        }
      } catch (BusException e) {
        e.printStackTrace();
      }

     cim.registerConduitInitiator(ns, this);
   }

   System.out.println();
   System.out.println( "Checking ConduitInitiator Mapping:" );

   for (String ns : activationNamespaces) {
    try {
     ConduitInitiator initor = cim.getConduitInitiator( ns );
     if ( initor != null ) {

       System.out.println( "For " + ns + ", " +  
initor.getClass().getName() );

     } else {
       System.out.println( "For " + ns + ", null" );
     }
   } catch (BusException e) {
      e.printStackTrace();
   }
 }
}

initHttpClient();

if ( this.httpClientInitialized.get() ) {
 System.out.println( "Commons HttpClient Initialized" );
} else {
 System.out.println( "Commons HttpClient Failed to initialize" );
}
//...
}

But, I can see my Client still is still using HTTPConduit. Is it  
too later

or any other configuration point or name
"org.apache.cxf.transport.http.ClientOnlyHTTPTransportFactory" is
referenced?  so far I can only make it work by renaming them as
ClientOnlyHTTPTransportFactory and delete the original one from
cxf-2.1.1.jar.


I guess my suggestion would be to put breakpoints in the Conduit  
manager stuff

to see what is registered.


I'll try to do it.

Thanks a lot for your help!

Hi Dan and Ulhas,

Thanks a lot for answering my previous message!


I tried to create a simple CommonsHttpClientTransportFactory  
with a simple
CommonsHttpClientConduit, and I tried to follow the suggestion  
Dan gave

at:

http://www.nabble.com/Using-HTTPClient-as-a-transport-td14715325.html#a16815394

I created a simple cxf-extension-commons-http.xml as:
===================================================

<import resource="classpath:META-INF/cxf/cxf-extension-

<bean

class 
= 
"org.apache.cxf.transport.http.CommonsHTTPClientTransportFactory"

<value>http://cxf.apache.org/bindings/xformat</value>

</property>
</bean>
====================================================

I created a simple WSDL2Java generated client, and I can see my
client logging output as:
====================================================

====================================================


Also, from my registerWithBindingManager() method, I tried to  
ensure

that the following namespaces are registered with the new
CommonsHTTPClientTransportFactory as:
====================================================
For http://schemas.xmlsoap.org/soap/http,
org.apache.cxf.transport.http.CommonsHTTPClientTransportFactory
For http://schemas.xmlsoap.org/wsdl/http/,
org.apache.cxf.transport.http.CommonsHTTPClientTransportFactory

org.apache.cxf.transport.http.CommonsHTTPClientTransportFactory
For http://cxf.apache.org/transports/http/configuration,
org.apache.cxf.transport.http.CommonsHTTPClientTransportFactory
For http://cxf.apache.org/bindings/xformat,
org.apache.cxf.transport.http.CommonsHTTPClientTransportFactory
===================================================


But, my client still uses the HTTPConduit as the following code  
snippet

==================================================
Client client = ClientProxy.getClient( port );


System 
.out.println( client.getConduit().getClass().getSimpleName() );
System 
.out 
.println( client.getConduitSelector().getClass().getSimpleName()

);
System.out.println(
client.getEndpoint().getEndpointInfo().getTransportId() );
==================================================
with output:

HTTPConduit
UpfrontConduitSelector
http://schemas.xmlsoap.org/soap/http


Is there any extra configuration steps required to let CXF  
Client use

my CommonsHttpClientConduit?

I really appreciate any tip and suggestion from your guys.

Thanks a lot for your help!
