Hi
The code given above has to be written in Web Dynpro at appropriate palce.
You have to follow following procedure for Creating a Web Dynpro iView as described in Help of NWDS.
   1.      In the portal, navigate to Content Administration ® Portal Content. The Portal Content Studio is opened.
       2.      In the Portal Catalog, navigate to the folder in which you want to create your new Web Dynpro-based iView. Create a new folder, if needed.
       3.      Click a folder in the Portal Catalog with the secondary mouse button and choose New ® iView in the context menu.
       4.      The iView wizard appears on the right. Select the appropriate standard iView template SAP Web Dynpro iView.
       5.      Choose Next.
       6.      On the next screen define the iView Name and the iView ID of the iView. The name is used as the title for the iView. The key is the technical name and the iView ID prefix can be used to define your own namespace.
       7.      Choose Next.
       8.      To specify the application variant select the definition type ABAP or Java.
       9.      On the next screen you have to define the Web Dynpro-specific properties:
                            a.      System
Choose the system alias you want to use for your Web Dynpro application from the dropdown list box. You have to create a system alias for each J2EE Engine first before you can run a Web Dynpro application on it. How to create a system and a system alias is described in detail earlier in Define a system
(If the Web Dynpro Application is deployed on the same J2EE Engine on which your portal is running then just Select SAP_LOCALSYSTEM from the dropdown)
                            b.      WebDynproNamespace
You have to define the development component containing your Web Dynpro application. If you are working locally without the DTR you have to define the Web Dynpro project used here. Make sure that both a development component and a Web Dynpro project contain the vendor name. For example, the following are possible values: sap.com/tcwdtools for a development component or local/MyWebDynproProject for a Web Dynpro project. For example in the “Creating a Simple Web Dynpro Application“ the project is called local/WebDynpro_Basics.
Note: The specified name of the development component is the same as displayed in the J2EE Engine console using the LIST_APP command or as used in the Web Dynpro application URL.
                            c.      Application Name
The application name is the name of the Web Dynpro application, for example WelcomeApplication.
                            d.      Application Parameters
If your Web Dynpro application has startup parameters you can define specific values for this iView. Imagine you have two parameters parameter1 and parameter2. In this case you could define the following application parameter string:  parameter1=value1&parameter2=value2.
   10.      After defining the Web Dynpro-specific properties the next wizard screen is displayed, which allows you to define other iView properties.
   11.      Choose Finish.
You can now use your Web Dynpro iView in the same way as any other iView, i.e. you can add the iView to pages, worksets or roles.
To preview the Web Dynpro iView, choose the Preview action in either the Portal Catalog (using the secondary mouse button) or in the iView Editor.
