2.5. XA Transactions

If the requesting application can participate in XA transactions, then your Connection object must override the getXAResource() method and provide the XAResource object for the application. To participate in crash recovery you must also extend the BasicResourceAdapter class and implement the public XAResource[] getXAResources(ActivationSpec[] specs) method.

Red Hat JBoss Data Virtualization can make XA-capable resource adapters participate in distributed transactions. If they are not XA-capable, the datasource can participate in distributed queries but not distributed transactions. Transaction semantics are determined by how you configured "connection-factory" in a "resource-adapter" (that is, jta=true/false).
