Method Detail

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.
Throws:
ResourceException - On failure.
See Also:
XATransactionalResource.refreshXAConnection()

usesXAResource

public boolean usesXAResource(XAResource res)
Description copied from class: XATransactionalResource
Test if the XAResource is used by this instance.

Overrides:
usesXAResource in class XATransactionalResource
Parameters:
res - The XAResource to test.
Returns:
boolean True iff this instance uses the same back-end resource, in as far as this can be determined by this instance.

recover

protected void recover()
Description copied from class: XATransactionalResource
Recover the contained XAResource, and retrieve the xid instances that start with our server's name.

Overrides:
recover in class XATransactionalResource

endRecovery

public void endRecovery()
Description copied from interface: RecoverableResource
Notify the resource that recovery is ended. Called by TM at end of recovery; any remaining resourcetransactions (i.e., that have not been associated with any recover call) should be rolled back. This is because if the were not recovered by the TM, then surely they are not supposed to be indoubt (the TM recovers ALL indoubt work!) and should be rolled back.

Specified by:
endRecovery in interface RecoverableResource
Overrides:
endRecovery in class XATransactionalResource
