Is there a way to configure eclipselink in order to persist numeric properties with content NULL as column with value ZERO ?
That's a requirement of a legacy database/application.

Thanks, Mauro.

The easiest way is to just change your object's type to a primitive, i.e. int instead of Integer, then it will never be null, or default the value in your constructor.

You could also configure a conversion for the specific mapping using a Converter. Or you could enable it for all mappings using a default null value for the type.

In a SessionCustomizer you can set the default null value,
i.e.

session.getLogin().setDefaultNullValue(Integer.class, 0);
