Persisting an object using JPA with predetermined ID

I need to persist() an object with an id, that I can specify. However I can't annotate the base class with a different @GeneratedValue. Can you assign a value generator just for a single persist? I have a specific use, please don't tell me that the id shouldn't be set manually.

Is there a way this can be done with JPA? Appreciate any hints!

[edited] @GeneratedValue annotation is present in the base class

@GeneratedValue is precisely used to tell JPA that it should generate the ID. If you want to assign the ID explicitely and don't want JPA to generate one for you, just don't use the @GeneratedValue annotation, assign the ID explicitely, and call persist().
