All Implemented Interfaces:

RecoverableResource, TransactionalResource

public class TemporaryXATransactionalResource
extends XATransactionalResource

A class for temporary resources. This is useful for configurations that don't register any XATransactionalResources in advance (zero setup). These cases require a dynamic and temporary XATransactionalResource to be added. This resource will be closed with the connection it is created on, and therefore is temporary.

refreshXAConnection

protected XAResource refreshXAConnection()
                                  throws ResourceException

Description copied from class: XATransactionalResource

Utility method to establish and refresh the XAResource. An XAResource is actually a connection to a back-end resource, and this connection needs to stay open for the transactional resource instance. The resource uses the XAResource regularly, but sometimes the back-end server can close the connection after a time-out. At intialization time and also after such a time-out, this method is called to refresh the XAResource instance. This is typically done by (re-)establishing a connection to the server and keeping this connection open!.

Specified by:

refreshXAConnection in class XATransactionalResource

Returns:

XAResource A XAResource instance that will be used to represent the server.
