Mapping entity bean to multiple datasources

Hi!

Is it possible to map a single container managed entity bean to multiple datasources / databases ?

I'm working with a system that has two databases and I need to keep some entities synchronized between them.

Thanks,

No. You can have two entities in different datasources, but not one entity in two different datasources.

Ok.

Is Jboss going to support this in some version?

Or is there any alternative solutions to this problem?

Maybe, but it is not very useful. You would be seriously limited in queries, because you can not join tables from different datasources.
