How to capture DB Errors and display as pop-up message

Question

Hi All,
I am using Jdeveloper 11g Release 2 (11.1.2.3.0).
In my AppModuleImpl.java, I defined a class to call PL/SQL procedure and exposed the same as Client interface. Pulled this method from data control on to a page a Button. The functionality is working fine.
Can you suggest me, what is best way to achieve the below functionality.
1. If there is any DB errors during PL/SQL procedure, how to catch and display the Errors / Warning in Pop-up message.
2. How to display info message on successful completion in Pop-up.

Throw a custom exception that extends the JboException class.

Option 1.
you can either return "true" or "false" from the method so that you can call
OperationBinding plsqlOperationBinding = .... get access to themethod binding to invoke the PLSQL method call ....
String result = plsqlOperationBinding.execute();
if(result.equlasIgnoreCase("true"){
RichPopup popup = ... get reference to popup defined on the page
RichPopup.PopupHints hints = new RichPopup.PopupHints ();
popup.show(hints);
Option 2
OperationBinding plsqlOperationBinding = .... get access to themethod binding to invoke the PLSQL method call ....
plsqlOperationBinding.execute();
if(plsqlOperationBinding.getErrors().size == 0){
RichPopup popup = ... get reference to popup defined on the page
RichPopup.PopupHints hints = new RichPopup.PopupHints ();
popup.show(hints);
