Re: [eclipselink-users] EclipseLink eclipselink.cache.shared.default persistence property
|
Nope, "eclipselink.cache.shared.default=true" is the default.
You can mark a class as read-only using the @ReadOnly annotation or xml.
Then it will not be cloned. You can also mark an individual query as
read-only using the "eclipselink.read-only"="true" hint.
