Hi All,
 
         I am developing a desktop application using swings.I am using Netbeans. I want to fetch database

 records and display it inside a jinternalframe. I have used jscrollpane. But not able to display records in

 jinternalframe. I am placing jscrollpane inside jpanel, and jpanel inside jinternal frame. Not able to

 add up code as the generated code from netbeans,doesnt allow to edit anything. Even if I try to add up

 code,not able to place in right place and execute my program.


  Please help...

  Thanks in advance
