                }
                data.addElement(rowdata);
            }
            t=new JTable(data,cNames);
        }
        catch(SQLException se){new SQLExceptionGUI(se).printMessage();}
        finally {}
        return t;
    }

but it is not displaying table on frame.

plz suggest any change...
thanks

Few things.

You usually put a Jtable in a scroll panel. You could make the return
object a JComponent and do a Return (new ScrollPane(t));

Secondly, you code does not show what you do with he table once it is
loaded. Example, where do you added it to your into a layout manager for
the Frame?
