I’m using persistence API and want to load jdbc URL from web.xml. URL should be a context parameter of servlet. I can’t find how to construct EntityManagerFactory not using persistence.xml. May be I should create PersistenceUnit in servlet and set some parameters? Can you give me some short example?
Thank you
you can use method
createEntityManagerFactory(String persistenceUnitName, Map properties)of classjavax.persistence.Persistence. and insert all your parameters in the map
