[jboss-user] [EJB 3.0] - multiple persistence unit in one persistence.xml

Can I use two and more datasource in one persistence.xml? When I use one persistence-unit tag in persistence.xml, it's work. When I added second persistence-unit tag in persistence.xml I received next error message anonymous wrote : 2007-03-26 16:18:24,646 WARN [org.jboss.resource.connectionmanager.JBossManagedConnectionPool] Throwable while attempting to get a new connection: null | org.jboss.resource.JBossResourceException: Could not create connection; - nested throwable: (java.sql.SQLException: ?????????? ?????/??????: Connection refused(DESCRIPTION=(TMP=)(VSNNUM=153093120)(ERR=12505)(ERROR_STACK=(ERROR=(CODE=12505)(EMFI=4))))) | at org.jboss.resource.adapter.jdbc.local.LocalManagedConnectionFactory.createManagedConnection(LocalManagedConnectionFactory.java:179) | at org.jboss.resource.connectionmanager.InternalManagedConnectionPool.createConnectionEventListener(InternalManagedConnectionPool.java:565) | at org.jboss.resource.connectionmanager.InternalManagedConnectionPool.getConnection(InternalManagedConnectionPool.java:250) | at org.jboss.resource.connectionmanager.JBossManagedConnectionPool$BasePool.getConnection(JBossManagedConnectionPool.java:491) | at org.jboss.resource.connectionmanager.BaseConnectionManager2.getManagedConnection(BaseConnectionManager2.java:341) | at org.jboss.resource.connectionmanager.TxConnectionManager.getManagedConnection(TxConnectionManager.java:301) | at org.jboss.resource.connectionmanager.BaseConnectionManager2.allocateConnection(BaseConnectionManager2.java:396) | at org.jboss.resource.connectionmanager.BaseConnectionManager2$ConnectionManagerProxy.allocateConnection(BaseConnectionManager2.java:842) | at org.jboss.resource.adapter.jdbc.WrapperDataSource.getConnection(WrapperDataSource.java:88) | at org.hibernate.connection.DatasourceConnectionProvider.getConnection(DatasourceConnectionProvider.java:69) | at org.hibernate.cfg.SettingsFactory.buildSettings(SettingsFactory.java:76) | at org.hibernate.cfg.Configuration.buildSettings(Configuration.java:1933) | at org.hibernate.cfg.Configuration.buildSessionFactory(Configuration.java:1216) | at org.hibernate.ejb.Ejb3Configuration.buildEntityManagerFactory(Ejb3Configuration.java:688) | at org.hibernate.ejb.HibernatePersistence.createContainerEntityManagerFactory(HibernatePersistence.java:127) | at org.jboss.ejb3.entity.PersistenceUnitDeployment.start(PersistenceUnitDeployment.java:264) | at sun.reflect.NativeMethodAccessorImpl.invoke0(Native Method) | at sun.reflect.NativeMethodAccessorImpl.invoke(NativeMethodAccessorImpl.java:39) | at sun.reflect.DelegatingMethodAccessorImpl.invoke(DelegatingMethodAccessorImpl.java:25) | at java.lang.reflect.Method.invoke(Method.java:585) | at org.jboss.ejb3.ServiceDelegateWrapper.startService(ServiceDelegateWrapper.java:102) | ....... | My persistence.xml : <?xml version="1.0" encoding="UTF-8"?> | <persistence> | <persistence-unit name="clrProd" transaction-type="JTA"> | <jta-data-source>java:/jdbc/ClrProdDS</jta-data-source> | <properties> | <property name="hibernate.dialect" value="org.hibernate.dialect.Oracle9Dialect"/> | </properties> | </persistence-unit> | | <persistence-unit name="clrArch"> | <jta-data-source>java:/jdbc/ClrArchDS</jta-data-source> | <provider>org.hibernate.ejb.HibernatePersistence</provider> | <properties> | <property name="hibernate.dialect" value="org.hibernate.dialect.Oracle9Dialect"/> | </properties> | </persistence-unit> | </persistence> View the original post : http://www.jboss.com/index.html?module=bb&op=viewtopic&p=4031908#...
