Subject [jira] Commented: (CXF-896) Aegis binding with @WebFault causes AegisDatabinding to throw UnsupportedOperationException
Date Tue, 11 Sep 2007 14:25:33 GMT

    [ https://issues.apache.org/jira/browse/CXF-896?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel#action_12526467
] 

Zarar Siddiqi commented on CXF-896:
-----------------------------------

Has anyone looked into this? I'm pretty sure this is a bug which makes it impossible to use
an Aegis binding while using @WebFault.  As mentioned in the original post this is happening
because Node.class is not being checked for in AegisDatabinding.createWriter().

Any ideas?

 Here's my setup starting with the Spring beans:
>     <bean id="aegisBean"
>           class="org.apache.cxf.aegis.databinding.AegisDatabinding"/>
>     <jaxws:endpoint
>             id="sportsServiceEndpoint"
>             implementor="#sportsService"
>             address="/SportsService">
>         <jaxws:serviceFactory>
>             <bean class="org.apache.cxf.jaxws.support.JaxWsServiceFactoryBean">
>                 <property name="dataBinding" ref="aegisBean"/>
>                 <property name="serviceConfigurations">
>                     <list>
>                         <bean class="org.apache.cxf.jaxws.support.JaxWsServiceConfiguration"/>
>                         <bean class="org.apache.cxf.aegis.databinding.AegisServiceConfiguration"/>
>                         <bean class="org.apache.cxf.service.factory.DefaultServiceConfiguration"/>
>                     </list>
>                 </property>
>             </bean>
>         </jaxws:serviceFactory>
>     </jaxws:endpoint>
> Here's the exception class:
> @WebFault(name="WebServiceException")
> public class WebServiceException extends RuntimeException {
>    // constructors hidden for brevity
>     public Object getFaultInfo() { .... }
> }
> Here's the stacktrace:
> java.lang.UnsupportedOperationException
>   at org.apache.cxf.aegis.databinding.AegisDatabinding.createWriter(AegisDatabinding.java:109)
>   at org.apache.cxf.jaxws.interceptors.WebFaultOutInterceptor.handleMessage(WebFaultOutInterceptor.java:82)
>   at org.apache.cxf.phase.PhaseInterceptorChain.doIntercept(PhaseInterceptorChain.java:207)

>   at org.apache.cxf.transport.servlet.ServletController.invokeDestination(ServletController.java:231)
> I can actually see this exception coming.  In WebFaultOutInterceptor.handleMessage()
the line
> DataWriter writer = service.getDataBinding().createWriter(Node.class) ;
> invokes AegisDatabinding.createWriter() where Node.class isn't being looked for:
>     public <T> DataWriter<T> createWriter(Class<T> cls) {
>         if (cls.equals(XMLStreamWriter.class)) {
>             return (DataWriter<T>)new XMLStreamDataWriter(this);
>         } else {
>             throw new UnsupportedOperationException();
>         }
>     }
> Any ideas how to avoid this exception? I think my configuration is correct and this might
be a bug.
