Return parameter of a Webservice model in web dynpro

Question

Hii,
I have imported one webservice model in my web dynpro application.
After execution, when web service returns 'NULL'  ( i checked in web service navigator)
but at the same time, the response node in web dynpro is NOT NULL and it is showing size 1 ??
How come this is possible? When i check the attributes of response node, they are all NULL...
Im checking response node this way==>
          wdContext.currentRequest_BodyShopUAViDocument_checkUsernamePasswordElement().setUsername(uniqueName);
wdContext.currentRequest_BodyShopUAViDocument_checkUsernamePasswordElement().setPassword("dummy");
wdThis.executeRequest_BodyShopUAViDocument_checkUsernamePassword();
if(wdContext.nodeResponse() == null){
      WDClientUser.forceLogoffClientUser("someURL");
Pls help me in resolving this...
regards,
Amey

Hi Manoj,
I'm checking webservice, this is the session bean method for which i hav created web service==>
public UserDTO checkUsernamePassword(String username, String password) {
// TODO : Implement
                UserDTO UserMasterResult = null;
          java.sql.Date sqlDate = null;
          java.util.Date utilDate = null;     
          try{
               Collection result = userMasterLocalHome.findByUsernamePassword(username,password);
               // If invalid user
               if (result.size() == 0)
                    return UserMasterResult;
               }else {
                    // Valid user found. Returning the details                              
                    UserMasterResult = new UserDTO();
                    for (Iterator it = result.iterator(); it.hasNext();) {
                         userMasterLocal = (UserMasterLocal) it.next();
                         UserMasterResult.setLoginid( userMasterLocal.getLoginid() );                         
                         UserMasterResult.setUsername(userMasterLocal.getUsername());
                         UserMasterResult.setPassword(userMasterLocal.getPassword());                         
                         UserMasterResult.setUserrole(userMasterLocal.getUserrole());
                         UserMasterResult.setEmail(userMasterLocal.getEmail());
                         UserMasterResult.setCreatedAt(userMasterLocal.getCreatedAt());
                         UserMasterResult.setCreatedBy(userMasterLocal.getCreatedBy());
                         UserMasterResult.setChangedAt(userMasterLocal.getChangedAt());
                         UserMasterResult.setChangedBy(userMasterLocal.getChangedBy());
                         UserMasterResult.setData1UserMaster(userMasterLocal.getData1UserMaster());
                         UserMasterResult.setData2UserMaster(userMasterLocal.getData2UserMaster());
                         UserMasterResult.setData3UserMaster(userMasterLocal.getData3UserMaster());     
          }catch(Exception e){               
               e.printStackTrace();
          return UserMasterResult;
