proper insertion of code in pre and post initialization to fetch records and display from database in jinternalframes

 Not able to fetch and display database records in jinternalframe. I am using palette manager to create

 jinternalframe,and then jpanel, and then i have placed jscrollpane. I hv tried to insert code in pre and post

 initialization,i.e. properties defined in palette manager. I hv used jtable to display records and I am adding

 that jtable to jscrollpane. Jinternal frame displays nothing when i run this program.

 PLEASE HELP.....
