Andy,

apparently you do some db stuff inside your jbInit which is 
causing the problem. Do you share a DataSet between login dialog
and main window? If so just do what the exceptions says: 
"Close the DataSet first" before reusing it inside jbInit.

If not you might want to repost to borland.public.jbuilder.database. 
It is not a Swing problem for sure. 

Good luck,
Torsten
