I've brought the datasource deployment metadata up-to-date with the JBoss5 MCFs. I think we still need to support the old ha-*-datasource xml for backwards compatiblity don't we? We should be able to support this by just doing something like? | @XmlType(name="ha-xa-datasource") | @XmlAccessorType(XmlAccessType.FIELD) | @ManagementObject(componentType=@ManagementComponent(type="DataSource",subtype="XA")) | public class HAXADataSourceDeploymentMetaData extends XADataSourceDeploymentMetaData | { | } | and then adding the dummy classes to the ManagedConnectionFactoryDeploymentGroup?
