how to use portlet preferences in jboss

[kuttima vs]

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..

Its all to worked in jboss... And i had attached some samples of code..

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>
<portlet>
<portlet-name>HelloWorldPortlet</portlet-name>
<portlet-class>org.jboss.portlet.hello.HelloWorldPortlet</portlet-class>

Which portal are you deploying to?

Correct me if I'm wrong, but isn't the portlet-instances.xml file unique to JBoss?
