Subject ClassCastException in BindingProvider casting when using CXF 2.4.2 on WAS 6.1 environment
Date Tue, 07 Aug 2012 19:56:28 GMT
My Web service Project is running on WAS 6.1 version with using CXF 2.4.2
libraries and it is configured in Maven pom files. This web service project
is working fine through our My tester application ( Dummy Consumer
Application ) and Non mavenized consumer application.  If one of the
consumer application ( which is mavenized ) is adding same jar dependencies
in their pom files and try to launch Credit Card application then it is
hitting with below error at runtime. In below code for JAXWSExecutor class
we are casting webServiceEndpoint object ( which is the instance of
JaxWsClientProxy) to BindingProvider. As per IBM recommendation to handle
this situation we did some settings in Server admin console for the
classloader if we are using third party JAX-WS web services and it is
working fine. But Consumer application want different solution which is
without classloader setting and it should be handled through Maven pom
settings or some other configuration without class loader. Because changing
the class loader policy is not acceptable by the Runtime team at my client.

Error :

java.lang.ClassCastException: $Proxy48 incompatible with
javax.xml.ws.BindingProvider
	at
sf.reqfwk.executor.JAXWSExecutor.setHeaderDetails(JAXWSExecutor.java:119)
	at sf.reqfwk.executor.JAXWSExecutor.execute(JAXWSExecutor.java:106)



JAXWSExecutor code where it is hitting with classcast exception

BindingProvider bp = (BindingProvider) webServiceEndpoint;  ( where
BindingProvider is of geronimo-jaxws_2.2_spec-1.0.jar )

So, Could you please suggest what is the solution without changing
classloader policy.
