Exclude Field in Class from JPA

Question

I have an entity in JPA. I recently added a field to my entity. I do not want this field to be persisted. However, Eclipselink is complaining about it not being in the table (which it obviously isnt).

How can I exclude this class from be looked at by JPA. Please note that this field cannot be transient.

You can add JPA's @Transient. Field annotated with Transient will not be persisted.

Awesome, will this still allow the field to be serialized too? – user489041 Feb 26 '15 at 16:12
Great, just implemented it, worked like a charm. I will accept this in a few min – user489041 Feb 26 '15 at 16:15

One option is adding @Transient annotation if on the other hand you use transient keyword that means the field won't be serialized. More on Why does JPA have a @Transient annotation?
