android - Pass Object to WCF service -

i totally new wcf service. don't know how pass complex type wcf service.

public class mainactivity extends activity implements onclicklistener { soapobject result; button b; private static string namespace = "http://tempuri.org/"; private static string method_name = "insertdata"; private static string soap_action = "http://tempuri.org/iwcfmastertable/insertdata"; private static string url = "http://172.16.0.1:55355/wcfmastertable.svc";  @override protected void oncreate(bundle savedinstancestate) {     super.oncreate(savedinstancestate);     setcontentview(r.layout.activity_main);     b = (button) findviewbyid(r.id.button1);     b.setonclicklistener(this); }  @override public void onclick(view v) {     if (v.getid() == r.id.button1) {         myclass mc = new myclass(mainactivity.this);         mc.execute("");     } }  class myclass extends asynctask<string, void, soapobject> {     jsonobject jobj;     mainactivity activity;      public myclass(mainactivity activity) {         this.activity = activity;     }      @override     protected soapobject doinbackground(string... params) {         try {             clsmastertable ct = new clsmastertable();             soapobject request = new soapobject(namespace, method_name);             ct = ct.getdata();             system.out.println(ct.tableid);             request.addproperty("args", ct);              soapserializationenvelope envelope = new soapserializationenvelope(                     soapenvelope.ver12);             envelope.setoutputsoapobject(request);             envelope.dotnet = true;             httptransportse transport = new httptransportse(url);             try {                 transport.call(soap_action, envelope);             } catch (exception e) {                 e.printstacktrace();             }              soapfault fault = (soapfault) envelope.bodyin;             system.out.println("fault : " + fault.tostring());             result = (soapobject) envelope.bodyin;             system.out.println("result : " + result);         } catch (exception e) {             system.out.println("exception : " + e.tostring());         }         return result;     }      @override     protected void onpostexecute(soapobject result) {         super.onpostexecute(result);     } } } 

and

public class clsmastercasetype { string id, name, mark;  public clsmastercasetype getdata() {     mark= "88";     id = "ctypaaaa0005";     name= "karthik";     return this; } } 

this way have tried pass complex type. throws following exception

08-08 12:53:42.376: w/system.err(7845): java.lang.runtimeexception: cannot serialize:   com.elintsys.wcfservice.clsmastercasetype@40fcbdf0 08-08 12:53:42.376: w/system.err(7845):     @ org.ksoap2.serialization.soapserializationenvelope.writeelement(soapserializationenvelope.java:687) 08-08 12:53:42.376: w/system.err(7845):     @ org.ksoap2.serialization.soapserializationenvelope.writeproperty(soapserializationenvelope.java:671) 08-08 12:53:42.386: w/system.err(7845):     @ org.ksoap2.serialization.soapserializationenvelope.writeobjectbody(soapserializationenvelope.java:640) 08-08 12:53:42.386: w/system.err(7845):     @ org.ksoap2.serialization.soapserializationenvelope.writeobjectbody(soapserializationenvelope.java:624) 08-08 12:53:42.386: w/system.err(7845):     @ org.ksoap2.serialization.soapserializationenvelope.writeelement(soapserializationenvelope.java:681) 08-08 12:53:42.386: w/system.err(7845):     @ org.ksoap2.serialization.soapserializationenvelope.writebody(soapserializationenvelope.java:597) 08-08 12:53:42.386: w/system.err(7845):     @ org.ksoap2.transport.transport.createrequestdata(transport.java:101) 

how pass object in soap request have tried way too. please me friends. wasted 3 days this. in advance.

i have made changes in code.

1)

soapserializationenvelope envelope = new soapserializationenvelope( soapenvelope.ver12);

change

soapserializationenvelope envelope = new soapserializationenvelope(soapenvelope.ver11);

2)

soapobject response = (soapobject) envelope.bodyin;

change into

soapprimitive response = (soapprimitive)envelope.getresponse();
