Unable to implement JUErrorHandler

Question

I'm trying to make my application show the simple error dialog every time jbo raise exception, not the error dialog of class JUErrorHandlerDlg.
I had already implemented JUErrorHandler and overrided method reportException() but it's still not work.
My code:
public class FormCurrenciesView extends JFrame implements JUErrorHandler
public static void main(String [] args)
try
JUApplication app = JUMetaObjectManager.createApplicationObject(...);
JUPanelBinding panelBinding = new JUPanelBinding(...);
app.getApplicationModule().fetchAttributeProperties(...);
panelBinding.setApplication(app);
FormCurrenciesView1 frame = new FormCurrenciesView(panelBinding);
JUMetaObjectManager.setBaseErrorHandler(frame);
catch(Exception ex)
JUMetaObjectManager.reportException(null, ex);
System.exit(1);
public void reportException(JUFormBinding formBnd, Exception ex){
JOptionPane.showMessageDialog(null, ex.getMessage(), "Error", JOptionPane.INFORMATION_MESSAGE);
Pls help me to solve this problem.
Thanks.

Sorry, I mean the JOptionPane.ShowMessageDlg() function doesn't show error dialog as it's supposed to do. The error handler, instead, print its error stacktrace in Jdev's debug window.
One more thing, I has tested my application with some changes:
I write a new class name MyJUErrorPane which is also implemented JUErrorHandler and overrided method reportException, my code right now is:
1: JUMetaObjectManager.setBaseErrorHandler(new MyJUErrorHandler());
2: JUApplication app = JUMetaObjectManager.createApplicationObject(...);
3: JUPanelBinding panelBinding = new JUPanelBinding(...);
4: app.getApplicationModule().fetchAttributeProperties(...);
5: panelBinding.setApplication(app);
6: FormCurrenciesView frame = new FormCurrenciesView(panelBinding);
The above code worked perfectly, class MyJUErrorHandler show the error mess correctly. But when I moved the top line to the bottom (moved line 1 to line 7)... nothing show but the stacktrace on debug window.
Have you got any idea ???
Thank you for your reply.
