create a new persistence unit programmatically and map it to a new datasource without redeploy or server restart ---------------------------------------------------------------------------------------------------------------- Key: JBAS-7474 URL: https://jira.jboss.org/jira/browse/JBAS-7474 Project: JBoss Application Server Issue Type: Feature Request Security Level: Public (Everyone can see) Components: Hibernate service Affects Versions: JBossAS-5.1.0.GA Environment: JBoss 5.1.0.GA Reporter: Dave Chen Assignee: Steve Ebersole Currently we use the persistence.xml to map a persistenceUnit to data source. Our application got a requirement: create a new persistence unit programmatically and map it to a new datasource without redeploy or server restart. How to achieve this functionality? EntityManagerFactory emf = Persistence.createEntityManagerFactory("manager1"); //or Map configOverrides = new HashMap(); configOverrides.put("hibernate.hbm2ddl.auto", "create-drop"); EntityManagerFactory programmaticEmf = Persistence.createEntityManagerFactory("manager1", configOverrides); But the persistence unit "manager1" needs to be defined in persistence.xml. What we need is: EntityManagerFactory emf = Persistence.createEntityManagerFactory("foo", "dataSourceName"); the persistence unit "foo" is not defined in any persistence.xml. -- This message is automatically generated by JIRA. - If you think it was sent incorrectly contact one of the administrators: https://jira.jboss.org/jira/secure/Administrators.jspa - For more information on JIRA, see: http://www.atlassian.com/software/jira
