[news.eclipse.technology.jsr220-orm] Re: Could not determine type for: [

["Robert Greene" <rgreene@xxxxxxxxxxx>]

Hi Mathias,

I doubt this is a bug.

This is a standard Hibernate mapping exception that usually happens when you
have a non-primitive attribute in your class that has not been properly
mapped.   I bet this has to do with another class that references your
customer, not the actual Customer class.    Is there another class that has
an attribute that is of type Customer.     If so, you probably need to
specify the OneToOne or ManyToOne annotation on that attribute.   That
should be where the problem resides.

Hope this helps ..
