I been using JPA since 1.0 (hibernate I must admint...) so,
How to handle new entities's IDs in an horizontal patitioned entities?

For example, I always use a sequence, in partitioned entities how I should do that?

How are you partitioning your entities? Are you using EclipseLink's partitioning support?

You don't need to partition the sequence object, just define it on one database and have all ids allocated from there (use a large preallocation size to improve performance).
