Re: [eclipselink-users] EM.clear() within a transaction and out of any t

[Andrei Ilitchev <andrei.ilitchev@xxxxxxxxxx>]

As far as committing objects to the data base is concerned, the comment 
to the method states:
/**
* Clear the persistence context, causing all managed
* entities to become detached. Changes made to entities that
* have not been flushed to the database will not be
* persisted.
*/

Another aspect is shared cache, which Eclipselink uses.
Calling clear in transaction means some objects may have been flushed to 
the data base, but won't be merged into the shared cache.

http://www.eclipse.org/eclipselink/api/1.1/org/eclipse/persistence/config/FlushClearCache.html 
describes the options.
