我有一个带有以下wsdl文件的WebService：

我使用Windows Phone SDK中的SlSvcUtil生成c＃SlSvcUtil.exe test.wsdl的代理类。

这是生成代码的一部分：

[System.Diagnostics.DebuggerStepThroughAttribute()]
[System.CodeDom.Compiler.GeneratedCodeAttribute("System.ServiceModel", "4.0.0.0")]
[System.ComponentModel.EditorBrowsableAttribute(System.ComponentModel.EditorBrowsableState.Advanced)]
[System.ServiceModel.MessageContractAttribute(WrapperName="getPOI", WrapperNamespace="com.test", IsWrapped=true)]
public partial class getPOI {

        [System.ServiceModel.MessageBodyMemberAttribute(Order=0)]
        [System.Xml.Serialization.XmlElementAttribute(Form = System.Xml.Schema.XmlSchemaForm.Unqualified)]
        public int ID;

        public getPOI() {
        }

        public getPOI(int ID) {
            this.ID = ID;
        }
}

private class BBAppWebAccessClientChannel : ChannelBase<BBAppWebAccess>, BBAppWebAccess
{

    public BBAppWebAccessClientChannel(System.ServiceModel.ClientBase<BBAppWebAccess> client) : 
            base(client)
    {
    }

    public System.IAsyncResult BegingetPOI(getPOI request, System.AsyncCallback callback, object asyncState)
    {
        object[] _args = new object[1];
        _args[0] = request;
        System.IAsyncResult _result = base.BeginInvoke("getPOI", _args, callback, asyncState);
        return _result;
    }

    public getPOIResponse EndgetPOI(System.IAsyncResult result)
    {
        object[] _args = new object[0];
        getPOIResponse _result = ((getPOIResponse)(base.EndInvoke("getPOI", _args, result)));
        return _result;
    }
}

getPOIResponse _result = ((getPOIResponse)(base.EndInvoke("getPOI", _args, result))); 抛出 FaultException 。

我使用以下代码调用WebService：

private void Load_Initial_Data()
{
    try
    {
        BBAppWebAccessClient wac = new BBAppWebAccessClient();
        wac.getPOICompleted += new EventHandler<getPOICompletedEventArgs>(client_GetDataCompleted);
        wac.getPOIAsync(1);
    }
    catch (Exception e)
    {
        Console.WriteLine(e.StackTrace);
    }

}
void client_GetDataCompleted(object sender, getPOICompletedEventArgs e)
{
    //this.DataContext = e.Result;
    Console.WriteLine(e.Result.poiID);
}

在服务器端有以下例外：

使用Fiddler（Windows Phone）捕获的消息：

<s:Envelope xmlns:s="http://schemas.xmlsoap.org/soap/envelope/">
    <s:Body xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:xsd="http://www.w3.org/2001/XMLSchema">
        <getPOI xmlns="com.test">
            <ID>1</ID>
        </getPOI><
    /s:Body>
</s:Envelope>

使用Fiddler（Axis2）捕获的消息：

<soapenv:Envelope xmlns:soapenv="http://schemas.xmlsoap.org/soap/envelope/">
    <soapenv:Body>
        <ns1:getPOI xmlns:ns1="com.test">
            <ID>1</ID>
        </ns1:getPOI>
    </soapenv:Body>
</soapenv:Envelope>

我该如何解决？生成的java代码（Apache Axis2）效果很好。

感谢您的任何建议。

我找到了解决方案。使用Java EE创建WebService时，必须添加所有名称空间，否则将出现上述错误 在修复 FaultException 之后，我得到了一个 NullReferenceException ，这表明我也必须修复响应处理。

非常感谢 @calum 。

以下是WebService的示例实现，它与Axis2和SLsvcUtil工具一起使用：

package com.test;

//imports here

@WebService(targetNamespace = "com.test")
public class BBAppWebAccess {
    @WebMethod
    @WebResult(targetNamespace="com.test.poi")
    public POI getPOI(
            @WebParam(name="ID", targetNamespace="com.test.poi")
            int id) {

        return new POI(id);
    }
}

新消息如下所示：

<s:Envelope xmlns:s="http://schemas.xmlsoap.org/soap/envelope/">
    <s:Body xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:xsd="http://www.w3.org/2001/XMLSchema">
        <getPOI xmlns="com.test">
            <ID xmlns="com.test.poi">1</ID>
        </getPOI>
    </s:Body>
</s:Envelope>

新生成的 getPOI 类：

[System.Diagnostics.DebuggerStepThroughAttribute()]
[System.CodeDom.Compiler.GeneratedCodeAttribute("System.ServiceModel", "4.0.0.0")]
[System.ComponentModel.EditorBrowsableAttribute(System.ComponentModel.EditorBrowsableState.Advanced)]
[System.ServiceModel.MessageContractAttribute(WrapperName="getPOI", WrapperNamespace="com.test", IsWrapped=true)]
public partial class getPOI {

    [System.ServiceModel.MessageBodyMemberAttribute(Namespace="com.test.poi", Order=0)]
    public int ID;

    public getPOI() {
    }

    public getPOI(int ID) {
        this.ID = ID;
    }
}

答案 1 :(得分：1)

看起来您正在向服务发送错误的类型（我假设这是因为错误表明发现了意外的元素'ID'，这意味着您的请求未正确形成）。 使用fiddler（如果可能）查看您要发送到服务器的内容。您可能能够弄清楚发生了什么，然后您可以更新生成的代码，以便发送正确的类型。
