[eclipselink-users] @EmbeeddedId vs @IdClass

[Christopher.Mathrusse@xxxxxxxxxx]

Is there any preference in which one to
use when it comes to composite Primary Keys? I can see from the documentation
that I can use either or, but I'm wondering which one is preferable. 

And if I decide to use the @Embeddable
annotation on my PrimaryKey class, and @EmbeddedId in my entity,  do
I need to annotate the Pk fields with @Column and @Id?

Thanks for the help...
