Subject Re: Migrating ejb 2.1 entity beans to jpa in weblogic

Hi Craig,
Thanks for the help.  Let me see if I understand correctly.

1.  our oracle 10g database only supports "read committed", "serializable"
and "read only" tranasction isolation levels.
2.  on the "write side", issuing an entitymanager.flush(), forces the
changes to the database.

my question: "I thought since the underlying database is set to
"read-committed", after executing the flush, only connections within the
current transaction would be able to read the changes to the database until
commit time."  Is this correct?
