What is missing, when I render my Application for Mobile Support, like PDA?

Question

Hello @ all,
I have a question about ADF Mobile.
I implemented a bean, which has a Method:
getRenderKitId(){
AdfFacesContext afc = AdfFacesContext.getCurrentInstance();
Agent agent = afc.getAgent();
if(Agent.TYPE_PDA.equals(agent.getType().toString()))               return "oracle.adfinternal.view.faces.ui.laf.simple.pda";          
else if(Agent.AGENT_GECKO.equals(agent.getAgentName()))
     return "com.apress.projsf.xul.ajax";
else if(Agent.AGENT_IE.equals(agent.getAgentName()) &&
Agent.TYPE_DESKTOP.equals(agent.getType()))
     return "com.apress.projsf.htc.ajax";
else if(Agent.AGENT_WEBKIT.equals(agent.getAgentName()))
     return "com.apress.projsf.html.ajax";
else
     return RenderKitFactory.HTML_BASIC_RENDER_KIT;
When I debug my Application on an PDA, this Method returns the right String for PDAs "oracle.adfinternal.view.faces.ui.laf.simple.pda".
I also have the public class DynamicRenderKitViewHandler extends ViewHandlerWrapper{
public String calculateRenderKitId(FacesContext context){
     String renderKitId = super.calculateRenderKitId(context);
     Matcher matcher = DYNAMICRENDER_KIT_ID.matcher(renderKitId);
     if(matcher.matches()){
     String expression = matcher.group(1);
          Application application = context.getApplication();
          ValueBinding binding = application.createValueBinding(expression);
          if(binding.getType(context) == String.class)
               renderKitId = (String) binding.getValue(context);
          return renderKitId;
The return Value of this Method is also oracle.adfinternal.view.faces.ui.laf.simple.pda.
So know my question is, what else do I have to implement, to render my components on a PDA. Because, when i run my Application on a Pocket PC 2003 with Windows CE, the Mobile Internet Browser shows me the same rendering page like it is on the "normal" PC Internet Browser.
Do I have to work with the ADF Faces Tags, like the <af:commandButton ...>
because, i don't use these tags.
The Libraries i have imported are, the adf-faces-api-10_1_3_0_4.jar file and simular the impl-jar.
Please could anybody help me?

Hello Jrozier,
first I wanne thank you for your reply.
Know my ApplicationBean getRenderKitId Method returns "oracle.adf.core"
I had wrote a little JSP that looks like the following:
<%@ taglib uri="http://xmlns.oracle.com/adf/faces/html" prefix="afh"%>
<afh:html>
<afh:head>
     <title>Test Page</title>          
</afh:head>
<afh:body>
Testing
</afh:body>
</afh:html>
But when I try to run my Application, I get the following error:
type Exception report
message
description The server encountered an internal error () that prevented it from fulfilling this request.

What could go wrong?
