How to access complex data type objects in webdynpro

Question

Hi
Need help on the detailed procedure to access the complex data type objects.
I am importing an external wsdl file, its request and response have complex data type objects , how do i access the same as the values are nested in them.
The structure of request and response at my end is as below:
request(I level)
--complextypeobject(II level)
requestheader(III level)
field1
field2
request
--response
messages
resp1
resp2
Any help would be highly appreciated.
Thanks and Regards,

here you go
WS Structure
Request_MI_PortWellOB_MI_PortWellOB
|-- MT_PortWellOut
   |--agency ( attr)
   |--user (attr)
   |-- well ( node)
     |-- borehole
     |-- downhole
     |-- interval
     |-- surface
// code to set complex type
          wdContext.nodeRequest_MI_PortWellOB_MI_PortWellOB().bind(new Request_MI_PortWellOB_MI_PortWellOB());
          //        port well object
          Request_MI_PortWellOB_MI_PortWellOB oPWRequest = new Request_MI_PortWellOB_MI_PortWellOB();
          ComplexType_DT_PortWell oPWParameters = new ComplexType_DT_PortWell();
          oPWRequest.setMT_PortWellOut(oPWParameters);
          wdContext.nodeRequest_MI_PortWellOB_MI_PortWellOB().bind(oPWRequest);
          DT_PortWell oPWInputbean =
               this.wdContext.nodeRequest_MI_PortWellOB_MI_PortWellOB().nodeMT_PortWellOut().currentMT_PortWellOutElement().modelObject().getOriginalBean();
          //       oPWInputbean.setTEST("test");
          //          well object
          DT_CWR_Well oWParameters = new DT_CWR_Well();
          //          all object
          //        surface
          DT_CWR_Surface oSParameters = new DT_CWR_Surface();
          ComplexType_DT_CWR_Surface s = new ComplexType_DT_CWR_Surface();
          //          Borehole
          DT_CWR_BoreHole[] oBParameters = new DT_CWR_BoreHole[wdContext.nodeBoreholedetail().size()];
          //          Downhole
          DT_CWR_DownHole[] oDParameters = new DT_CWR_DownHole[wdContext.nodeDownholedetail().size()];
          //          Interval
          DT_CWR_Interval[] oIParameters = new DT_CWR_Interval[wdContext.nodeIntervaldetail().size()];
          //        add all into well object       
          oWParameters.setSURFACE(oSParameters);
          oWParameters.setBOREHOLE(oBParameters);
          oWParameters.setDOWNHOLE(oDParameters);
          oWParameters.setINTERVAL(oIParameters);
          //       oPWParameters.setWELL(oWParameters );      
          oPWInputbean.setWELL(oWParameters);
          oPWRequest.setMT_PortWellOut(oPWParameters);
          wdContext.nodeRequest_MI_PortWellOB_MI_PortWellOB().bind(oPWRequest);
          wdContext.currentMT_PortWellOutElement().setUSERID("user");
          wdContext.currentMT_PortWellOutElement().setAGENCY("agency");
