pp11222 Exception Handling in a global class which can be consumed by VF page or other apex classes
how to do the exception handling in a global void apex class, which can be consumed by VF page or other apex classes.
I have some global void apex classes which were created in a manged release packages and now I cannot change their signatures or return value. These classes are called from VF pages and are also avaiable for other customers so that can use them in their custom code. but they do not have proper exception handling.
I want to know how can I trap the exceptions (DML Exceptions) in other classes or VF Pages.
Please provide some sample code.
Thanks
