java - 如何使用 AXis 1.4 创建 Java 客户端以使用 wsHttpBinding 使用 WCF 服务

Question

我创建了一个 java 客户端，用于使用 axis 1.4 使用 WCF 服务。如果我使用 basicHttpBinding 则一切正常，但如果我使用 wsHttpBinding 则出现以下错误:-

Did not understand "MustUnderstand" header(s):{http://www.w3.org/2005/08/addressing}Action

请告诉我如何解决此错误。谢谢。

当您使用 Axis 为 WCF 服务生成代理时，它会生成自动为 http://www.w3.org/2005/08/设置 MustUnderstand header 的 stub 寻址

下面的代码将 MustUnderstand 标志重置为 false。对于被调用的方法。我今天遇到了类似的问题，并且能够使用此处发布的代码解决

//maybe someother service stub,i show you a case
    CommentWcfServiceLocator locator =new CommentWcfServiceLocator();
    WSHttpBinding_ICommentServiceStub stub;
    try {       
    //get a stub and set service url
    stub = (WSHttpBinding_ICommentServiceStub)   locator.getWSHttpBinding_ICommentService(new         java.net.URL("http://www.google.com/CommentWcfService.svc"));

    // the key is here , importantest!!! follow this
    // set action, action path,you can find in your java code
    SOAPHeaderElement action = new SOAPHeaderElement(new QName("wsa:Action"),     "http://tempuri.org/ICommentService/GetCommentSummaryByHotelId");
    SOAPHeaderElement to = new SOAPHeaderElement(new QName("wsa:To"),
    stub._getProperty(javax.xml.rpc.Stub.ENDPOINT_ADDRESS_PROPERTY));
        action.setActor(null);
        action.setNamespaceURI("http://www.w3.org/2005/08/addressing");
        to.setActor(null);
        to.setNamespaceURI("http://www.w3.org/2005/08/addressing");
         // set header
                stub.setHeader(action);
        stub.setHeader(to);
                // must set this property
        stub._setProperty(Call.CHECK_MUST_UNDERSTAND, Boolean.FALSE);
            stub.getCommentSummaryByHotelId("","02201158", 0);
    } 
catch(Exception EX){}

我找到了 this post关于 MustUnderstand 非常有帮助。
