Can't cast ServiceClient to WSBindingProvider

[Maxim Che]

Hello!

So I have this web service(based on axis2) which is supposed to act as a client to other web service. But when trying to cast my servicePort (docManClient) to WSBindingProvider I get ClassCastException error:

com.sun.proxy.$Proxy283 cannot be cast to com.sun.xml.internal.ws.developer.WSBindingProvider

What confuses me is that this code works ok when execution from simple java application, but when execution from web service it fails. Also I've noticed that when executed from simple java application docManClient is a SEIStub object but when this code is executed inside my axis2 webservice, docManClient is JAXWSProxyHandler. I don't know if that helps or what should I do.

How can I fix or analyse deeply this classcast exception? Is there a way to avoid casting it to WSBindingProvider and set headers with JAXWSProxyHandler?

Thanks in advance.

DocumentManagement_Service docManService = new DocumentManagement_Service();
DocumentManagement docManClient = docManService.getBasicHttpBindingDocumentManagement();
DocumentManagement docManClientP = docManService.getBasicHttpBindingDocumentManagement(null);
		
try
{
	// The namespace of the OTAuthentication object
	final String ECM_API_NAMESPACE = "urn:api.ecm.opentext.com";

	// Create a SOAP header
	SOAPHeader header = MessageFactory.newInstance().createMessage().getSOAPPart().getEnvelope().getHeader();

	// Add the OTAuthentication SOAP header element
	SOAPHeaderElement otAuthElement = header.addHeaderElement(new QName(ECM_API_NAMESPACE, "OTAuthentication"));

	// Add the AuthenticationToken SOAP element
	SOAPElement authTokenElement = otAuthElement.addChildElement(new QName(ECM_API_NAMESPACE, "AuthenticationToken"));
	authTokenElement.addTextNode(authToken);

	// Set the SOAP header on the docManClient
	
	//Object pt = docManService.getPort(do);

	//ServiceClient sc = docManService.getServiceClient(docManService.getServiceName())
	
	//BindingProvider bp =  ((BindingProvider) docManClient);
	
	((WSBindingProvider) docManClient).setOutboundHeaders(Headers.create(otAuthElement));

For those who found this topic and facing the same problem. My solution was to use javax.xml.ws.BindingProvider class instead of com.sun.xml.internal.ws.developer.WSBindingProvider. This way casting went well.

One good man from a different forum suggested not to use packages from JDK(com.sun.* или com.oracle.*) because their methods could be deprecated or changed without notice. I guess something like that happened because I used an old WebService API manual and something could change.

What changes did you make in the code?
