Teamcenter Engineering - Setting up Eclipse RCP

[kevsmi]

TcEng 10.0, Eclipse 3.2, Java SDK 1.4.2_05
Trying to setup Eclipse for RCP Customization of TcEng
I have done the following basic steps:
1. set up a new project in Eclipse
2. have added all the .jar files listed in the portal.bat file in the IMAN_Root\portal directory
3. have created a new configuration with com.ugsolutions.aif.AIFPortal as the main class

I am getting the following error:
Error occurred.Registry Error
java.lang.Exception: Registry Errog
at com.ugsolutions.aif.AIFDesktopToolBAr.<init>(Unknown Source)
at com.ugsolutions.aif.AIFDesktop.constructToolBar(Unknown Source)
at com.ugsolutions.aif.AIFPortal.main(Unknown Source)
and similar.......

In DEBUG mode -
AIFPortal.Class - Class File Editor
Source Not Found

Any IDEAS ? / Suggestions ?

Thanks
