java - 无法将 ServiceClient 转换为 WSBindingProvider

Question

所以我有这个网络服务（基于axis2），它应该作为其他网络服务的客户端。但是当尝试将我的 servicePort (docManClient) 转换为 WSBindingProvider 时，我收到 ClassCastException 错误：

com.sun.proxy.$Proxy283 无法转换为 com.sun.xml.internal.ws.developer.WSBindingProvider

让我感到困惑的是，当从简单的 Java 应用程序执行时，这段代码可以正常工作，但是当从 Web 服务执行时它会失败。我还注意到，当从简单的 java 应用程序执行时，docManClient 是一个 SEIStub 对象，但是当此代码在我的axis2 webservice 中执行时，docManClient 是 JAXWSProxyHandler。我不知道这是否有帮助或我应该怎么做。

如何修复或深入分析此 classcast 异常？有没有办法避免将其转换为 WSBindingProvider 并使用 JAXWSProxyHandler 设置标头？

提前致谢。

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));
