[opencms-dev] OpenJpa - best way to access EntityManager inside OpenCms

[Georgi Naplatanov]

Hi,

You have looked where the methods are - > org.opencms.db.jpa.CmsSqlManager

If you want to use EntityManager instances from OpenCms' persistence 
unit and use corresponding db pool, use 
getEntityManager()/returnEntityManager, but if you want to use different 
persistence unit - use getFactory() or createEntityManager().

The source code is very simple so it's your friend :)

HTH

Best regards
Georgi
