Using ADF with Eclipse

Question

Hi guys,
I'm trying to create a sample project using ADF Faces (only the JSF components, no bindings or anything else). Target server is WebLogic 10.3 and IDE is Eclipse 3.4.
First of all, I'm not entirely clear on the relationship between ADF Faces and Trinidad. I know that the former has been donated by Oracle to Apache and it later became the Trinidad project, but how is the current Trinidad project related to the ADF Faces components delivered with WebLogic 10.3? Is there any advantage in using the commercial distribution instead of Trinidad? As I said, we don't want to use the rest of the ADF framework (bindings and all).
Secondly, my deployment has been failing for multiple reasons. The current situation has the WebLogic console displaying the following warning :
28-Jan-2009 5:13:54 PM oracle.adfinternal.view.faces.renderkit.core.CoreRenderKit _addBasicHTMLRenderKit
WARNING: Could not find basic HTML renderer for family javax.faces.SelectMany, type=javax.faces.Checkbox
When I try to load the page, the console shows the following error:
java.lang.NullPointerException
     at com.sun.faces.renderkit.RenderKitUtils.getResponseStateManager(RenderKitUtils.java:253)
     at com.sun.faces.lifecycle.RestoreViewPhase.isPostback(RestoreViewPhase.java:267)

     at oracle.adf.view.faces.webapp.AdfFacesFilter.doFilter(AdfFacesFilter.java:87)
My current setup is as follows:
- WebLogic 10.3 with latest patches
- domain is configured to support Application Development Framework (is this necessary?)
- web.xml declares:
* context-param: oracle.adf.view.faces.ALTERNATE_VIEW_HANDLER = com.sun.facelets.FaceletViewHandler
* filter: adf-filter = oracle.adf.view.faces.webapp.AdfFacesFilter
* servlet: faces-servlet = javax.faces.webapp.FacesServlet (load-on-startup = 1)
* servlet: adf-resources-servlet = oracle.adf.view.faces.webapp.ResourceServlet
* listener: com.sun.faces.config.ConfigureListener
- weblogic.xml declares:
* library reference to JSF 1.2
- faces-config.xml declares:
* default-render-kit-id = oracle.adf.rich
- JAR dependencies:
* adf-faces-api
* adf-faces-impl
* adf-share
* adf-facelets
* jsf-facelets
Does this setup make any sense at all?
Thanks,
GB

Hi Shay,
Thank you for your answers. The ADF-Trinidad relationship is now clear to me.
I have installed JDeveloper 11g and succeeded in creating a simple ADF Faces application then deploying it to a stand-alone WebLogic instance. I've learned through the process that even JDeveloper struggles to deploy the application as a WAR, and only succeeds when deploying it as an EAR file.
I am now trying to upgrade this simple application to use Facelets instead of JSPs. JDeveloper 11g has Facelets support but it seems that it cannot mix Facelets and ADF components - after creating a new Facelets page, the Resource Palette only shows standard JSF components and the ADF Faces components are nowhere to be found. Surely I must be missing something?
Given this, I tried updating my setup to include Facelets rendering but I'm running into more troubles. I get one of 2 results depending on how I configure the servlet mapping for the Faces servlet.
1. If I map the Faces servlet to /faces/*, the page renders, normal HTML tags are rendered but all JSF tags (standard and ADF) are not rendered, they are simply copied verbatim to the web page (as seen in the HTML source). I also get the following message in the console:
30-Jan-2009 9:42:21 AM oracle.adfinternal.view.faces.activedata.SessionDataUpdateManager __getPageDataUpdateManager
SEVERE: cannot register active data when window has no name2. If I map the Faces servlet to *.xhtml, I get the following exception:
