Hi Knut, Thank you for your reply. So now, I use the ClientConnectionPoolDataSource as DataSource into my OpenJPA configuration. But getPooledConnection[X](...) methods aren't invoked by the ORM, only getConnection[X]() methods inherited from ClientBaseDataSource are invoked.
I don't know if this is the good behaviour, should getConnection[X](...) methods be overloaded into ClientConnectionPoolDataSource and return getPooledConnection[X](...). getConnection() ? Regards, Guillaume
