Hi friends !
I want my dynamic data to be displayed in my portlet which i will give it thro' my preferences..
Im able to access my preferences.. But my problem is im getting my default value only.. Not my dynamic value..

My java file...


protected void doView(RenderRequest rRequest, RenderResponse rResponse) throws PortletException, IOException, UnavailableException
{
PortletPreferences pref = rRequest.getPreferences();
System.out.println("Hello______Portlet: oView:Entered");
rResponse.setContentType("text/html");
PrintWriter writer = rResponse.getWriter();
writer.write("doView :: "+ pref.getValue("color","0"));
writer.close();
System.out.println("Hello______Portlet: oView:Exiting");
}



My Porlet.xml....

<portlet-app>
