I would like to know if simple Java types (i.e. int) are supported with the non-null set to false. I am getting a null exception when the value retrieved from the DB is NULL. It works if I use the wrapper class (i.e. Integer).

Thanks.

The primitive types in java cannot be null. Each will default to a certain value (e.g. boolean is false) when added as a field on a class without being initialised.

Wrapper classes are objects, so they can be null.
