[jboss-user] [Beginners Corner] - How to configure XA Datasource for JBoss 4.2.2 and Postgres?

I am on JBoss 4.2.2 and I need to configure XA Datasource for Postgres. Here is exempt from my postgres-ds.xml | <datasources> | <xa-datasource> | <jndi-name>DefaultDS</jndi-name> | <connection-url>jdbc:postgresql://some_url/ecommdb</connection-url> | <driver-class>org.postgresql.Driver</driver-class> | <user-name>some_name</user-name> | <password>foo</password> | | <!-- sql to call when connection is created --> | <new-connection-sql>select count(*) from status</new-connection-sql> | | <!-- sql to call on an existing pooled connection when it is obtained from pool --> | <check-valid-connection-sql>select count(*) from status</check-valid-connection-sql> | | <!-- corresponding type-mapping in the standardjbosscmp-jdbc.xml (optional) --> | <metadata> | <type-mapping>PostgreSQL 7.2</type-mapping> | </metadata> | </xa-datasource> | ...... | </datasources> But when I try connecting to this database I get the following exception: anonymous wrote : Caused by: org.jboss.resource.JBossResourceException: Could not create connection; - nested throwable: (org.jboss.resource.JBossResourceException: No XADataSourceClass supplied!) | at org.jboss.resource.adapter.jdbc.xa.XAManagedConnectionFactory.createManagedConnection(XAManagedConnectionFactory.java:144) | at org.jboss.resource.connectionmanager.InternalManagedConnectionPool.createConnectionEventListener(InternalManagedConnectionPool.java:577) | at org.jboss.resource.connectionmanager.InternalManagedConnectionPool.getConnection(InternalManagedConnectionPool.java:262) | at org.jboss.resource.connectionmanager.JBossManagedConnectionPool$BasePool.getConnection(JBossManagedConnectionPool.java:500) | at org.jboss.resource.connectionmanager.BaseConnectionManager2.getManagedConnection(BaseConnectionManager2.java:341) | at org.jboss.resource.connectionmanager.TxConnectionManager.getManagedConnection(TxConnectionManager.java:315) | at org.jboss.resource.connectionmanager.BaseConnectionManager2.allocateConnection(BaseConnectionManager2.java:396) | at org.jboss.resource.connectionmanager.BaseConnectionManager2$ConnectionManagerProxy.allocateConnection(BaseConnectionManager2.java:842) | at org.jboss.resource.adapter.jdbc.WrapperDataSource.getConnection(WrapperDataSource.java:88) | ... 84 more What did I miss?
