Re: [eclipselink-users] javax.persistence.NoResultException

EclipseLink only weaves Entities so as long as you're only using AOP on non-Entity classes you should be ok.

Remember that EclipseLink weaves as well so there could be some
funkiness using another agent, but ya that's a good way to do it :)

I ended up using AOP to intercept the exception and return null because our
previous ORM returned null and I didn't want to rewrite/redesign the entire
system. I guess that's always an option.

Unfortunately the JPA spec requires the exception.  However I agree that
null
would be more useful, I would recommend you log an enhancement request in
Bugzilla for a query hint or persistence property that allows null to be
returned instead of an exception.

Hello

I did get the following exception:
javax.persistence.NoResultException: getSingleResult() did not retrieve
any entities.

This exception is correct, because there was nu such object in the db.
But if the object doesn't exist, I want to return a null object and not
a NoResultException

Is there a way how I can do that?

Leon
