Hi,
I have primitive java long type field on my POJO. If there is a record in the database table for this POJO and the corresponding column value for the long type is of value null, the exception:

org.hibernate.PropertyAccessException: Null value was assigned to a property of primitive type setter.....

in cases when the entity is queried.

I read the hibernate spec, it says one way around this is to use a Java wrapper object and make the field a Long instead of a long.

Now, I want to keep it a primitive. I would have thought if this field is optional, it should be allowed to null, even if it is a primitive.

My understanding is that optional=true is the default but I mark the field explictly to be optional using:

@Basic(optional=true)

I still get the same exception.

Any ideas how I can get around this?

I wish to use primitives who's setters will be ignored should the value be null in the database.

Thanks

As soon as you manage to compile

I'll make the change :-)

BTW you can achieve what you want by using @Type and writing your own user type that does the magic

Hi,

I am facing the same problem. Why would you create your own UserType?
Can't you just work with the Long wrapper class. That class should be able to handle NULL values, doesn't it?

Kind regards,
