How to handle Exception using ExceptionHandler?

[ashwin_4421]

Hi ,
I have the following requirement:
1.An actionHandler will throw an SblException
2.After the exception is created, a mail has to be sent to an user using another ActionHandler.

My process defintion contains:




<exception-handler exception-class='com.sample.action.SblException>

</exception-handler>



SblAction can throw an SblException and then the MailerAction should send out an email-notification.

But the control never seems to rreach the MailerAction class.
Ami i missing something?
Thanks
Ashwin

The ExceptionHandler class does not use the process class loader when it loads the exception-class to verify it is assignable from the thrown exception. As a workaround, try placing the exception class in the classpath and remove it from the process archive.
