Hi,
I tried persistince with both Hibernate and Toplink for a pretty starightforward Entity in my application.


However observed that SaleItem is NOT getting persisted (when I do a select * from SaleItem) unless I uncomment EntityTransaction, xact.begin and xact.commit.
And even if it is not persisted, when I use em.find, it prints properly!

What basic am I missing here?

You must call commit() to have any changes committed to the database. In JPA changes are made to the object model in memory, to have the changes flushed to the database, either flush() or commit() must be called. The find() will find the object in the persistence context, even if it has not been flushed.
