Method Details

registerXAResource

public static void registerXAResource(String uniqueName,
 XAResource xaResource)

Register an XAResource of a cache with BTM. The first time a XAResource is registered a new EhCacheXAResourceProducer is created to hold it.

Parameters:

uniqueName - the uniqueName of this XAResourceProducer, usually the cache's name

xaResource - the XAResource to be registered

unregisterXAResource

public static void unregisterXAResource(String uniqueName,
 XAResource xaResource)

Unregister an XAResource of a cache from BTM.

Parameters:

uniqueName - the uniqueName of this XAResourceProducer, usually the cache's name

xaResource - the XAResource to be registered

startRecovery

public XAResourceHolderState startRecovery()
                                    throws RecoveryException

Prepare the recoverable XAResource producer for recovery.

Specified by:

startRecovery in interface XAResourceProducer

Returns:

a XAResourceHolderState object that can be used to call recover().

Throws:

RecoveryException - thrown when a XAResourceHolderState cannot be acquired.

endRecovery

public void endRecovery()
                 throws RecoveryException

Release internal resources held after call to startRecovery().

Specified by:

RecoveryException - thrown when an error occured while releasing reserved resources.

setFailed

public void setFailed(boolean failed)

Mark this resource producer as failed or not. A resource is considered failed if recovery fails to run on it.

Specified by:

setFailed in interface XAResourceProducer

Parameters:

failed - true is the resource must be considered failed, false it it must be considered sane.

findXAResourceHolder

public XAResourceHolder findXAResourceHolder(XAResource xaResource)

Find in the XAResourceHolders created by this XAResourceProducer the one which this XAResource belongs to.

Specified by:

findXAResourceHolder in interface XAResourceProducer

Parameters:

xaResource - the XAResource to look for.

Returns:

the associated XAResourceHolder or null if the XAResource does not belong to this XAResourceProducer.

init

public void init()

Parameters:

xaFactory - the vendor's resource-specific XA factory.

bean - the resource-specific bean describing the resource parameters.

Returns:

a XAStatefulHolder that will be placed in an XAPool.

Throws:

Exception - thrown when the XAStatefulHolder cannot be created.
