Changing the exception thrown using ServerRequestInterceptor

Hi,

Is it possible to change a SystemException thrown by an object
implementation to a UserException using Interceptors?

I haven't been able to use the send_exception api to do this.

Is there any other way to do this.

It is not possible to change the object implementation behaviour.

Would help if I could get some pointers.

Thanks and Regards,
M Shetty
