Unable to send an array inside a nested object using ksoap

Question

i wish to generate a soap request like :

<soapenv:Body>
    -
    <Perform xmlns="eras.in">
        -
        <request>
            <ActionName>Connect</ActionName>
            -
            <Input xmlns:ns1="eras.in" xsi:type="ns1:Record">
                <ns1:EntityName>Credential</ns1:EntityName>
                -
                <ns1:Fields>
                    -
                    <ns1:Field>
                        <ns1:Key>DomainName</ns1:Key>
                        <ns1:Value xsi:type="ns2:guid"
                            xmlns:ns2="http://schemas.microsoft.com/2003/10/Serialization/">Check2</ns1:Value>
                    </ns1:Field>
                    -
                    <ns1:Field>
                        <ns1:Key>UserName</ns1:Key>
                        <ns1:Value xsi:type="ns3:guid"
                            xmlns:ns3="http://schemas.microsoft.com/2003/10/Serialization/">utsav</ns1:Value>
                    </ns1:Field>
                    -
                    <ns1:Field>
                        <ns1:Key>Password</ns1:Key>
                        <ns1:Value xsi:type="ns4:guid"
                            xmlns:ns4="http://schemas.microsoft.com/2003/10/Serialization/">xxxxx</ns1:Value>
                    </ns1:Field>
                </ns1:Fields>
            </Input>
        </request>
    </Perform>
</soapenv:Body>

But I am able to generate something like :

<v:Body>
    <Perform xmlns="eras.in">
        <request i:type="n0:ActionRequest" xmlns:n0="eras.in">
            <ActionName i:type="d:string">Connect</ActionName>
            <sessionId i:null="true" />
            <Input i:type="n0:Record">
                <EntityName i:type="d:string">Credential</EntityName>
                <RecordId i:null="true" />
                <Fields i:type="n0:Fields">
                    <Field i:type="n0:Field">
                        <Key i:type="d:string">DomainName</Key>
                        <Value i:type="d:string">Check2</Value>
                    </Field>
                    <Field i:type="n0:Field">
                        <Key i:type="d:string">UserName</Key>
                        <Value i:type="d:string">utsav</Value>
                    </Field>
                    <Field i:type="n0:Field">
                        <Key i:type="d:string">Password</Key>
                        <Value i:type="d:string">xxx</Value>
                    </Field>
                </Fields>
            </Input>
        </request>
    </Perform>
</v:Body>

At the server when I check I see that Fields array is a null object.

Can somepne please help?

I suspect in the serverside object there is an array of type Field named Fields. Whereas i send a vector object named as Fields. Is this causing a problem?

Or is it because the field tags are missing the namespace prefix?

Thanks and Regards.

My Java code is :

       SoapObject request = new SoapObject(NAMESPACE, METHOD_NAME); 
       SoapSerializationEnvelope envelope = new        SoapSerializationEnvelope(SoapEnvelope.VER11);
      ActionRequest ERequest = new ActionRequest();
      ERequest.setActionName("Connect");
      Record r = new Record();
      r.setEntityName("Credential");
      Fields fs = new Fields();
      fs.add(new Field("DomainName","Check2"));
      fs.add(new Field("UserName","utsav"));
      fs.add(new Field("Password","xxxx"));
      r.setFields(fs);
      ERequest.setInput(r);
      request.addProperty("request",ERequest);
      envelope.setOutputSoapObject(request);
  envelope.dotNet = true;
  envelope.setAddAdornments(false);
  envelope.implicitTypes = true;

Answer 1

It is much easier to use SoapObject for arrays in ksoap as you get better control over the namespaces. An example for eras service connect request is shown below ...

private static final String NAMESPACE = "eras.in" ;
private static final String URL = "https://eras.in/Host/";
private static final String SOAP_ACTION = "eras.in/IActionService/Perform";
private static final String METHOD_NAME = "Perform";

public static void main(String[] args) {

    SoapSerializationEnvelope envelope = new SoapSerializationEnvelope(SoapEnvelope.VER11);
    SoapObject request = new SoapObject(NAMESPACE, METHOD_NAME);
    SoapObject actionRequest = new SoapObject(NAMESPACE, "ActionRequest");

    request.addProperty("request", actionRequest);
    actionRequest.addProperty("ActionName", "Connect");

    SoapObject record = new SoapObject(NAMESPACE, "Record");
    actionRequest.addProperty("Input", record);

    record.addProperty("EntityName", "Credential");

    SoapObject fields = new SoapObject(NAMESPACE, "ArrayOfField");
    record.addProperty("Fields", fields);

    SoapObject domain = new SoapObject(NAMESPACE, "Field");
    domain.addProperty("Key", "DomainName");
    domain.addProperty("Value", "<your domain name>");
    fields.addSoapObject(domain);

    SoapObject user = new SoapObject(NAMESPACE, "Field");
    user.addProperty("Key", "UserName");
    user.addProperty("Value", "<your username>");
    fields.addSoapObject(user);

    SoapObject pwd = new SoapObject(NAMESPACE, "Field");
    pwd.addProperty("Key", "Password");
    pwd.addProperty("Value", "<your password>");
    fields.addSoapObject(pwd);

    envelope.setOutputSoapObject(request);
    envelope.dotNet = true;

    HttpTransportSE httpTransport = new HttpTransportSE(URL);
    try
    {
        httpTransport.call(SOAP_ACTION, envelope);
        SoapObject response = (SoapObject)envelope.getResponse();
        System.out.println(response.toString());
    }
    catch(Exception e)
    {   
        e.printStackTrace();
    }
}   

Notice the line

SoapObject fields = new SoapObject(NAMESPACE, "ArrayOfField");
record.addProperty("Fields", fields);

Where Fields is the property of Record class and the type of this property is an array of Field, that is:

class Record
{
    Field[] Fields;
    ...
}
