Issue with Hibernate validation

[mrt2100]

Hi all,
I'm attempting to use a hibernate validation annotation inside one of the generated service layer classes. I added the hibernate validation jar to my build path but still come up with errors based inside my package declaration. Attached is a screenshot of the errors I receive. What could be a way to fix this?

Also is it a good idea to place hibernate validator annotations in my generated classes? Are there other annotations that would be better/easier to use inside any class in the service layers? (ie spring validator annotations)

Any help is appreciated, thanks.
