客户端找不到 {} 的调度方法 [英] Client Cannot find dispatch method for {}

问题描述

我有这个示例代码:

    private static final String endpoint = "https://www.***.**:443/WSEndUser?wsdl";

    public static void main(String[] args) throws SOAPException {
        SOAPMessage message = MessageFactory.newInstance().createMessage();
        SOAPHeader header = message.getSOAPHeader();
        header.detachNode();
/*
        SOAPEnvelope envelope = message.getSOAPPart().getEnvelope();
        envelope.setAttribute("namespace","namespaceUrl");
*/
        SOAPBody body = message.getSOAPBody();
        QName bodyName = new QName("getVServers");
        SOAPBodyElement bodyElement = body.addBodyElement(bodyName);
        SOAPElement symbol = bodyElement.addChildElement("loginName");
        symbol.addTextNode("my login name");
        symbol = bodyElement.addChildElement("password");
        symbol.addTextNode("my password");

        SOAPConnection connection = SOAPConnectionFactory.newInstance().createConnection();
        SOAPMessage response = connection.call(message, endpoint);
        connection.close();

        SOAPBody responseBody = response.getSOAPBody();
        SOAPBodyElement responseElement = (SOAPBodyElement)responseBody.getChildElements().next();
        SOAPElement returnElement = (SOAPElement)responseElement.getChildElements().next();
        if(responseBody.getFault()!=null){
            System.out.println("1) " + returnElement.getValue()+" "+responseBody.getFault().getFaultString());
        } else {
            System.out.println("2) " + returnElement.getValue());
        }
    }

我收到了这个错误:

1) S:Client 找不到 {}getVServers

1) S:Client Cannot find dispatch method for {}getVServers

但我知道该方法存在...有什么问题?

but i know that the method exists... whats wrong?

推荐答案

如果仍有问题，请也发布 WSDL.

Please post the WSDL too if you still have problems.

1) Web 服务调用失败，因为它找不到名为 getVServers 且命名空间为 {}(空命名空间)的方法.

1) The web service invocation fails because it can't find a method called getVServers with namespace {} (empty namespace).

您的请求类似于:

<SOAP-ENV:Envelope xmlns:SOAP-ENV="http://schemas.xmlsoap.org/soap/envelope/">
    <SOAP-ENV:Body>
        <getVServers>
            <loginName>my login name</loginName>
            <password>my password</password>
        </getVServers>
    </SOAP-ENV:Body>
</SOAP-ENV:Envelope>

getVServers 位于默认命名空间.它应该是这样的，其中命名空间应该是您的 WSDL 定义中的 targetNamespace:

getVServers is on the default namespace. It should be something like this, where the namespace should be targetNamespace from your WSDL definition:

<SOAP-ENV:Envelope xmlns:SOAP-ENV="http://schemas.xmlsoap.org/soap/envelope/">
    <SOAP-ENV:Body>
        <ns:getVServers xmlns:ns="http://your-namespace-from-wsdl.com">
            <loginName>my login name</loginName>
            <password>my password</password>
        </ns:getVServers>
    </SOAP-ENV:Body>
</SOAP-ENV:Envelope>

为了添加命名空间，请更改创建 bodyName 的方式:

In order to add a namespace change the way you create bodyName:

QName bodyName = new QName("http://your-namespace-from-wsdl.com", "getVServers", "ns");

如果在您的 XML 架构上设置了 elementFormDefault="qualified" 或者 form="qualified" 存在于您的元素中.

Also loginName and password may need to be prefixed if elementFormDefault="qualified" is set on your XML Schema or if form="qualified" is present on your elements.

2) 我认为您的 URL 端点不应包含 ?wsdl.

2) I think your URL endpoint should not contain ?wsdl.

3) 您正在尝试连接到 HTTPS 网络服务.请确保相应地设置您的证书和 DefaultSSLFactory.

3) You are trying to connect to a HTTPS webservice. Make sure you setup your certificates and DefaultSSLFactory accordingly.
