public static oracle.toplink.sessions.Session getSession(SessionFactory sessionFactory, boolean allowCreate) throws DataAccessResourceFailureException, IllegalStateException
true
.
This is the getSession
method used by typical data access code,
in combination with releaseSession
called when done with
the Session. Note that TopLinkTemplate allows to write data access code
without caring about such resource handling.
sessionFactory
- TopLink SessionFactory to create the session withallowCreate
- if a non-transactional Session should be created when no
transactional Session can be found for the current thread
DataAccessResourceFailureException
- if the Session couldn't be created
IllegalStateException
- if no thread-bound Session found and
"allowCreate" is false
releaseSession(oracle.toplink.sessions.Session, org.springframework.orm.toplink.SessionFactory)
,
TopLinkTemplate
public static oracle.toplink.sessions.Session doGetSession(SessionFactory sessionFactory, boolean allowCreate) throws oracle.toplink.exceptions.TopLinkException, IllegalStateException
true
.
Same as getSession
, but throwing the original TopLinkException.
