I'm using hibernate inside JBoss with an Oracle datasource. Usually when I do JDBC queries against the datasource it uses the schema as defined in the -ds.xml. But with hibernate I have to add the hibernate.default_schema property in persistence.xml too: | <persistence-unit name="jpaPersistence"> | <jta-data-source>java:/MainDS</jta-data-source> | ... | <properties> | <property name="hibernate.default_schema" value="guy" /> | ... | I've got a set up where the schema changes a lot between environments and ususally I can change the -ds.xml in deploy/ and that's all that needs doing. However with hibernate have to change the persistence.xml file inside the EAR too - I want to avoid have to change the EAR file if I can help it. I was wondering if there was a way of making hibernate pick up the default schema from the datasource? View the original post : http://www.jboss.org/index.html?module=bb&op=viewtopic&p=4250078#...
