Java Development Tools

I am using JDeveloper 3.1 to develop a fixed asset application. I have designed a logon frame with userid Textfield,password Textfield, OK button and Cancel button so that all users should enter a USERID and PASSWORD at the logon frame. When the OK button is clicked the application should authenticate the user whose userid and password are stored in a table calles USERAUTHENTICATION in Oracle database. After which the main application frame should display. The first problem i'm having is that the driver is not loading and Hence it does not do what i want. Can any one help me?. my email:winnersln@onebox.com

Below is my code:
