Issue while accessing properties of the PCD iview using PCD API

Hi,

    I am trying to access PCD iview properties using PCD API. I got the below exception:

    com.sap.portal.pcm.iview.admin.AttributeSetiView incompatible with com.sap.portal.pcm.iview.IiView

    Here is the code:

         Hashtable env = new Hashtable();

        env.put(Context.INITIAL_CONTEXT_FACTORY,IPcdContext.PCD_INITIAL_CONTEXT_FACTORY);

        env.put(Context.SECURITY_PRINCIPAL, request.getUser());

        env.put(Constants.REQUESTED_ASPECT, PcmConstants.ASPECT_SEMANTICS);

        String id = "pcd:portal_content/google";

        InitialContext iCtx = null;

        try {

        iCtx = new InitialContext(env);

        IiView result=(IiView) iCtx.lookup(id); // getting Exception at this line

        response.write(result.getAttribute("com.sap.portal.pcm.Title",request.getLocale()));

            }

        catch ( Exception e)

{

        response.write(e.getMessage());

}

   Can someone help me on this.

Regards,

Lakshmi
