I used the SlSvcUtil from the Windows Phone SDK to generate the proxy classes for c# SlSvcUtil.exe test.wsdl.

This is a part from the generated code:

[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;
    }
}

The FaultException is thrown by that getPOIResponse _result = ((getPOIResponse)(base.EndInvoke("getPOI", _args, result)));.

I call the WebService with following code:

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);
}

On the server side there is following exception:

Message captured with Fiddler (Axis2):

How can I fix it? The generated java code (Apache Axis2) works great.

Thanks for any advices.

I found the solution. When you are creating the WebService with Java EE you have to add all namespaces, otherwise you will get the errors above.
After fixing the FaultException, I got a NullReferenceException, which indicates that I have to fix the response handling, too.

Thanks a lot to @calum.

Here is a sample implementation of the WebService, which works together with Axis2 and the SLsvcUtil tool:

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);
    }
}

The new message looks like following:

<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>

The new genereated getPOI class:

[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;
    }
}
