Hi.
I have been checking PetClinic example of Spring framework in order to know how to handle exceptions in Spring&Hibernate&Web-based interface.
The example throughs DataAccessException which is a sucbclass of RuntimeException.
When an exception accured at Hibernate level, a stack trace web page is displayed.
This is not what I want to do -I can't let the user see this page, it is unfriendly-.
So, how to handle data access exceptions in Spring&Hibernate&Web interface ?
Thanks.

What are you using at the web layer? If using struts, you can define an a general exception handler for dataaccessexception. And for specific cases of data access exception, you might want to catch them in the Action layer and render differently.
