Unable to generate Entity Classes from Database in Netbeans v 6.8

[SanjayPethe]

Hello,
I get the following error when trying to generate entity classes from database (right click on Project - New - Enttity Classes from Database ...)

This is with Netbeans 6.8 using a MySQL database (MySQL 5.1.41-3ubuntu12.9) on Ubuntu 10.04

The project properties shows that it is using the Java Server Faces framework, thought it does not seem I can add any more (Add button is grayed out).

Am I missing some required component?

Any help is much appreciated.

Thanks,
SGP
