webservice

Hello everyone,

I am calling a web service from android using ksoap2. However I am having a problem in sending complex type parameters. I have a wsdl which has a method "invokeservice" :

<message name="invokeService">
<part name="serviceName" type="xsd:string"/>
<part name="documents" type="tns:uriList"/>
<part name="literalDocs" type="ns1:stringArray"/>
<part name="connID" type="xsd:long"/>
<part name="gateParams" type="tns:gateRuntimeParameterArray"/>
<part name="userCtx" type="tns:userContext"/>
</message>

for the property "gateParams" which is of type "gateRuntimeParameterArray" , you have :
<xs:complexType name="gateRuntimeParameterArray" final="#all">
<xs:sequence>
<xs:element name="item" type="tns:gateRuntimeParameter" minOccurs="0" maxOccurs="unbounded" nillable="true"/>
</xs:sequence>
</xs:complexType>

this "item" of type "gateRuntimeParameter" has :
<xs:complexType name="gateRuntimeParameter">
<xs:sequence>
<xs:element name="booleanValue" type="xs:boolean" minOccurs="0"/>
<xs:element name="corpusValue" type="xs:anyType" nillable="true" minOccurs="0" maxOccurs="unbounded"/>
<xs:element name="defaultValueString" type="xs:string" minOccurs="0"/>
<xs:element name="doubleValue" type="xs:double" minOccurs="0"/>
<xs:element name="intValue" type="xs:int" minOccurs="0"/>
<xs:element name="label" type="xs:string" minOccurs="0"/>
<xs:element name="optional" type="xs:boolean"/>
<xs:element name="PRName" type="xs:string" minOccurs="0"/>
<xs:element name="paramName" type="xs:string" minOccurs="0"/>
<xs:element name="pipelineName" type="xs:string" minOccurs="0"/>
<xs:element name="stringValue" type="xs:string" minOccurs="0"/>
<xs:element name="type" type="xs:string" minOccurs="0"/>
<xs:element name="urlValue" type="xs:anyURI" minOccurs="0"/>
</xs:sequence>
</xs:complexType>

I created classes gateRuntimeParameter.java and "gateRuntimeParameterArray.java" which implement kvmserializable.

public class gateRuntimeParameterArray implements KvmSerializable{

    public gateRuntimeParameter[] item ;//= new gateRuntimeParameter[1];
    //public List<gateRuntimeParameter> item = new ArrayList<gateRuntimeParameter>();
    public void setItemArray(int index,gateRuntimeParameter value)
    {
        System.out.println("Filling array of gate params at "+index+" with value: "+value.prName);
        item[index] = value;
        //item.add(value);
        System.out.println("Filling is done ! "+item[index].defaultValueString);
    }
    @Override
    public Object getProperty(int arg0) {
        switch (arg0){
        case 0:
            return item;
        default:
            return null;

        }
    }

    @Override
    public int getPropertyCount() {

        return 1;
    }

    @Override
    public void getPropertyInfo(int arg0, Hashtable arg1, PropertyInfo arg2) {
        switch(arg0)
        {
        case 0:
            arg2.type = gateRuntimeParameter.class;
            //arg2.type = uriList.getClass();
            arg2.name = "item";
            break;

        default:break;
        }

    }

    @Override
    public void setProperty(int arg0, Object arg1) {
        switch(arg0)
        {
        case 0:

            item = (gateRuntimeParameter[])arg1;
            //item = (List<GateRuntimeParameterArray>)arg1;

            break;

        default:
            break;
        }

    }

}

public class gateRuntimeParameter implements KvmSerializable

}

}
}

and I am doing:

gateRuntimeParameterArray gtParamArr = new gateRuntimeParameterArray();

gateRuntimeParameter gtRTparam = new gateRuntimeParameter();

Then I fill the gtRTparam, then I do following:

pi = new PropertyInfo();
pi.setName("gateParams");
pi.setValue(gtParamArr.item);

pi.setType(gateRuntimeParameterArray.class);

sobj.addProperty(pi);

and then I add mapping plus marshalling:

soapEnvelope.addMapping(namespace, gateRuntimeParameter.class.getSimpleName(), gateRuntimeParameter.class);
soapEnvelope.addMapping(namespace, gateRuntimeParameterArray.class.getSimpleName(), gateRuntimeParameterArray.class);
Marshal floatMarshal = new MarshalFloat();
floatMarshal.register(soapEnvelope);

However I keep getting Exception : Cannot serialize: [Lcom.example.NLPAndroid.gateRuntimeParamer;@44f05d38

I have been trying since 3 days, but can't understand what am i doing wrong? I have the following stack trace:

I know I wrote a lot but please I need your help, I have a demo in a week and if this doesn't work, I won't be able to show anything :(

Thanks a lot.
