Hi Mathi,
It is better to create the project by your self.
Here is the following  Steps
Step 1: Create a WebDynpro project.
Step2 :  Right click on the model =>create Model => Import Adaptive Web Service Model=>Next=>Give Model Name(say FlightDetails)/PackageName/Model Instances/RFC Meta Data =>Next => Give SAP logon information for single server(Host Name/System Number/client/logon name/password/language)=>Next=>Give the Function Name(Bapi_Flight_Getlist) =>Next=>Finished
Step3 : Create a Webdynpro component(say FlightDetailsComp).
Step4: Right Click on the Used Model add the model(FlightDetails) that you have created using RFC.
Step 4 :   Double-Clicks on the Component controller and Create a Value node(FlightInput) set Cardinality(0..1) and a Value Attribute(airlineid) under the node.
                                  FlightInput
                                     |_ airlineid
Step5 : Double-Clicks on the ComponentName(FlightDetailsComp) and open the the Diagram view and do the Mapping between component controller and used model (FlightDetails), views and component controller.
[In the context Model node structure will be like
                            Bapi_Flight_Getlist_Input
                                     |-Output
                                               |------ Flight_List
                                                        |---Attributes
                                     |- Airline
Step6: Go to the Component Controller then select “Method” Tab and create the following three methods.
i>     getOVSInputNode return type com.sap.tc.webdynpro.progmodel.api.IWDNode
ii>     getOVSListener return type com.sap.tc.webdynpro.progmodel.api.IWDOVSContextNotificationListener
iii>     getOVSOutputNode retun type
                com.sap.tc.webdynpro.progmodel.api.IWDNode
Step7:
Go to the Implementation tab and provide the following implementation for the functions
1>   public void wdDoInit()
    //@@begin wdDoInit()
     wdContext.nodeFlightInput().bind(wdContext.createFlightInputElement());
     Bapi_Flight_Getlist_Input bapiInput = new Bapi_Flight_Getlist_Input();
     wdContext.nodeBapi_Flight_Getlist_Input().bind(bapiInput);
    //@@end
2>  public com.sap.tc.webdynpro.progmodel.api.IWDNode getOVSInputNode( )
    //@@begin getOVSInputNode()
    return wdContext.nodeBapi_Flight_Getlist_Input();
    //@@end
3> public com.sap.tc.webdynpro.progmodel.api.IWDOVSContextNotificationListener getOVSListener( )
    //@@begin getOVSListener()
    return ovsListener;
    //@@end
4>  public com.sap.tc.webdynpro.progmodel.api.IWDNode getOVSOutputNode( )
    //@@begin getOVSOutputNode()
    return wdContext.nodeFlight_List();
    //@@end
5>
//@@begin others
  private IWDOVSContextNotificationListener ovsListener = new OVSNotificationListener();
       private class OVSNotificationListener implements IWDOVSContextNotificationListener {
            public void onQuery(
                 IWDNodeElement queryInputNodeElement,
                 IWDNode queryOutputNode) {
                      //Type custing of node element
                 IPublicFilghtDetailsComp
                      .IBapi_Flight_Getlist_InputElement ovsInput =
                      ( IPublicFilghtDetailsComp
                    .IBapi_Flight_Getlist_InputElement) queryInputNodeElement;
                                     IPublicFilghtDetailsComp.IFlight_ListNode ovsOutput =
                                     (IPublicFilghtDetailsComp.IFlight_ListNode) queryOutputNode;
                 try {
                      ovsInput.modelObject().execute();
                      ovsInput.node().getChildNode("Output", 0).invalidate();
                 } catch (Exception e) {
                      IWDMessageManager msgMgr = wdComponentAPI.getMessageManager();
                      msgMgr.reportException(e.getLocalizedMessage(), false);
            // Setting result to Value node elwment
            public void applyResult(IWDNodeElement applicationNodeElement,IWDNodeElement queryOutputNodeElement)
                 IWDMessageManager msg = wdControllerAPI.getMessageManager();
                 IPrivateFlightDetailsView.IFlightInputElement  flightElement = (IPrivateFlightDetailsView.IFlightInputElement) applicationNodeElement;
                 IPublicFilghtDetailsComp.IFlight_ListElement outputElm = (IPublicFilghtDetailsComp.IFlight_ListElement)queryOutputNodeElement;
               flightElement.setAirlineid(outputElm.getAirlineid());
            //Setting Input for search
            public void applyInputValues(IWDNodeElement applicationNodeElement,IWDNodeElement queryInputNodeElement)
Step7: Go to the View(FilightDetailsView) then select “Layout” Tab and design the layout.
    Like    Airline : FlightInput.airlineid
Take a ToolbarInputField  and give the “labelText” value Airline and “value” property value “value     FlightInput.airlineid.
Step8: Go to the Implementation and provide the code.
  public void wdDoInit()
    //@@begin wdDoInit()
     IWDAttributeInfo[] ovsStartUpAttributes =
               wdContext.nodeFlightInput()
                              .getNodeInfo()
                              .getAttribute("airlineid")
          IWDOVSContextNotificationListener listener =
               wdThis.wdGetFilghtDetailsCompController().getOVSListener();
               if (listener != null) {
                    WDValueServices.addOVSExtension(
                         "Flight Details",
                         ovsStartUpAttributes,
                         wdThis.wdGetFilghtDetailsCompController().getOVSInputNode(),
                         wdThis
                              .wdGetFilghtDetailsCompController()
                              .getOVSOutputNode(),
                         listener);
    //@@end
Step9: Create an Application(say FilghtApp) .
Step10 : Build and Deploy.
