Consuming ABAP Webservice in Webdynpro app

Question

Hi,
I have wrote a webdynpro app for consuming ABAP webservice. I used the procedure in the link below
http://wiki.sdn.sap.com/wiki/display/WDJava/ConsumingABAPWebServiceinJavaWD
Everything seemed to be went well, I created model and Webservice destinations. I have written the code for calling the webservice, which does not return data as part of response. I mean though the RFC returns data at the backend,its not showing the returned records in the webdynpro table.
I have also tried checking the same by setting external break point. when the webservice is executed from my webdynpro app,it goes to the ABAP debugger and i could clearly see the records in the export parameters of RFC,but the same is not returned in the reponse object.
Could any one let me know what could be missing. Any help is greatly appreciated?
I have used the following code in Init method of my View
Request_ZMYRFC input=new Request_ZMYRFC (model);
wdContext.nodeRequest_ZMYRFC ().bind(input);
ZMYRFC  req= new ZMYRFC (model);
req.setPUserid("EDLAS00C");
req.setPLtc("E");
input.setMYRFC (req);
IWDMessageManager manager = wdComponentAPI.getMessageManager();
    try
    wdContext.currentRequest_ZMYRFCElement().modelObject().execute();
      wdContext.nodeResponse().invalidate();
      wdContext.nodeZMYRFCResponse().invalidate();
      wdContext.nodeReturn_res().invalidate();
     wdContext.nodeItem_res_ret().invalidate();
      wdContext.nodeILtcg_res().invalidate();
      wdContext.nodeItem_res_ltcg().invalidate();
    catch(Exception e)
      manager.reportException(e.getMessage(), false);
Thanks

santosh,
Check provider system defination in nwa for webservice.After this mapp the provider system and service group after wd app deployed.This is mandatory while consuming webservice in webdynpro for latest versions of CE7.11 or later.for reference check this article/document. http://www.sdn.sap.com/irj/scn/index?rid=/library/uuid/50d70a19-45a3-2b10-bba0-807d819daf46
Thanks,
