Re: How to create a Spring-CXF Client Proxy

Tue, 06 May 2008 14:33:12 -0700 


Are you on CXF 2.1 or 2.0.6?

If so, I would suggest just doing:

  <import resource="classpath:META-INF/cxf/cxf-all.xml"/>
That will get all the cxf stuff with a single import and not need the wildcard (which in spring is pretty slow). 


Next question:
Have you tried using the jaxws:client bean definition we show at the bottom of: 
http://cwiki.apache.org/CXF20DOC/jax-ws-configuration.html
Your two bean defs can drop to a single line.

<jaxws:client
    id="foodBeverageFacilityServiceProxy"
serviceClass ="com.wdpr.core.facility.wsdl.FoodBeverageFacilityServiceSEI" 
    address="${food.beverage.facility.service.provider.url}"/>
Actually, the other option might be to not import any of the cxf stuff and DON'T set the bus property on the factory. In that case, it may create a default bus which would load everything anyway.

Thanks for the pointer, Willem. Sadly it did not work:

   <import resource="classpath:META-INF/cxf/cxf.xml"/>
   <import resource="classpath*:META-INF/cxf/cxf-extension-*.xml"/>

   <context:component-scan
base-package="com.wdw.avail.service.consumer.food.beverage.facility"/>

   <bean id="foodBeverageFacilityServiceProxyFactory"
         class="org.apache.cxf.jaxws.JaxWsProxyFactoryBean">
       <property name="serviceClass"
value="com.wdpr.core.facility.wsdl.FoodBeverageFacilityServiceSEI"/>
       <property name="address"
value="${food.beverage.facility.service.provider.url}"/>
       <property name="bus" ref="cxf"/>
   </bean>

   <bean id="foodBeverageFacilityServiceProxy"
class="com.wdpr.core.facility.wsdl.FoodBeverageFacilityServiceSEI" 
         factory-bean="foodBeverageFacilityServiceProxyFactory"
         factory-method="create"/>

The same exception is thrown:

I get your point on the 'cxf' bus being initialized via the cxf.xml. But the DestinationFactoryManager appears to be null, despite being created as well 
(and being on the classpath in cxf-2.0.6.jar).
Has anybody successfully created a JAX-WS client proxy and deployed via a war file? Again, the above Spring configuration works outside of a war in a 
unit test.

Thanks!

Aha, another bus issue.
Please see my comments in the mail.

You should not define the bus explicitly without any other cxf
components (such as the DestinationFactoryManager instance) injected.



   <bean id="foodBeverageFacilityServiceProxyFactory"
         class="org.apache.cxf.jaxws.JaxWsProxyFactoryBean">
       <property name="clientFactoryBean">
<bean class="org.apache.cxf.jaxws.JaxWsClientFactoryBean"/> 
       </property>
       <property name="serviceClass"
value="com.wdpr.core.facility.wsdl.FoodBeverageFacilityServiceSEI"/>
       <property name="address"
value="${food.beverage.facility.service.provider.url}"/>
       <property name="bus" ref="bus"/>


You need to change the reference bean's name to "cxf ", which is the
default bus that you import with "META-INF/cxf/cxf.xml"[1]

   </bean>

   <bean id="foodBeverageFacilityServiceProxy"

class="com.wdpr.core.facility.wsdl.FoodBeverageFacilityServiceSEI"
         factory-bean="foodBeverageFacilityServiceProxyFactory"
         factory-method="create"/>
I have tried creating the above client proxy with or without the 'bus' 
and
'clientFactoryBean'. Either way, I always get this exception:

Caused by: java.lang.NullPointerException
        at
org .apache .cxf .frontend .AbstractWSDLBasedEndpointFactory .createEndpointInfo(AbstractWSDLBasedEndpointFactory.java:155) 
        at
org .apache .cxf .frontend .AbstractWSDLBasedEndpointFactory .createEndpoint(AbstractWSDLBasedEndpointFactory.java:97) 
        at
org .apache .cxf.frontend.ClientFactoryBean.create(ClientFactoryBean.java:51) 
        at
org .apache .cxf .frontend .ClientProxyFactoryBean.create(ClientProxyFactoryBean.java:92) 

We all know the offending code:

154.                DestinationFactoryManager dfm =
getBus().getExtension(DestinationFactoryManager.class);
155. df = dfm.getDestinationFactoryForUri(getAddress());
That said, my unit (integration) test works like a charm. Once I deploy 
the
above client proxy in a web app to WAS6.1, though, the exception occurs. FWIW, I have followed the WAS cxf wiki instructions, which did not alter 
the
outcome.

Any thoughts?

Thanks!
