I tried in JBuilder3 which uses JDK1.2. I am getting this exception when I
incorporate my bean just derived from JTabbedPane and try to run. Even in
the designer I cannt see the tabs eventhough i added panels to it.

//
Exception occurred during event dispatching:
java.lang.ClassCastException: com.borland.jbcl.layout.XYLayout
 at
javax.swing.plaf.basic.BasicTabbedPaneUI.ensureCurrentLayout(BasicTabbedPane
UI.java:757)

javax.swing.plaf.basic.BasicTabbedPaneUI.paint(BasicTabbedPaneUI.java:350)

 at javax.swing.JComponent.paint(Compiled Code)
 at javax.swing.JComponent.paintChildren(Compiled Code)
 at javax.swing.JComponent.paint(Compiled Code) .........

I am really confussed ?
