Sessions and Transactions I want to make sure I understand the session-per-conversation pattern where there is a long running Session (cache) and multiple database transactions.

A single application transaction usually spans several database transactions. It will be atomic if only one of these database transactions (the last one) stores the updated data, all others simply read data.

13. Session-per-conversation with HB really the holy grail?    forum.hibernate.org

Hi, experts. After reading and testing a little bit the Session-per-conversation-pattern using Hibernate's FlushMode.MANUAL (as described in "JPA with HB") i'm quite disappointed about it. Since nothing is flushed to the database until the final manual flush, its impossible to use queries to find new or changed entites from the current conversation! With the default flush-mode AUTO the Session is flushed ...
