Class AbstractMessageEndpointFactory

java.lang.Object
  org.springframework.jca.endpoint.AbstractMessageEndpointFactory

Direct Known Subclasses:

GenericMessageEndpointFactory, JmsMessageEndpointFactory

public abstract class AbstractMessageEndpointFactory
extends java.lang.Object

Abstract base implementation of the JCA 1.5/1.6 javax.resource.spi.endpoint.MessageEndpointFactory interface, providing transaction management capabilities as well as ClassLoader exposure for endpoint invocations.

Method Detail

setTransactionManager

public void setTransactionManager(java.lang.Object transactionManager)

Set the the XA transaction manager to use for wrapping endpoint invocations, enlisting the endpoint resource in each such transaction.

The passed-in object may be a transaction manager which implements Spring's TransactionFactory interface, or a plain javax.transaction.TransactionManager.

If no transaction manager is specified, the endpoint invocation will simply not be wrapped in an XA transaction. Check out your resource provider's ActivationSpec documentation for local transaction options of your particular provider.

See Also:

setTransactionName(java.lang.String), setTransactionTimeout(int)

setTransactionFactory

public void setTransactionFactory(TransactionFactory transactionFactory)

Set the Spring TransactionFactory to use for wrapping endpoint invocations, enlisting the endpoint resource in each such transaction.

Alternatively, specify an appropriate transaction manager through the "transactionManager" property.

If no transaction factory is specified, the endpoint invocation will simply not be wrapped in an XA transaction. Check out your resource provider's ActivationSpec documentation for local transaction options of your particular provider.

setTransactionName(java.lang.String), setTransactionTimeout(int)

setTransactionName

public void setTransactionName(java.lang.String transactionName)

Specify the name of the transaction, if any.

Default is none. A specified name will be passed on to the transaction manager, allowing to identify the transaction in a transaction monitor.

setTransactionTimeout

public void setTransactionTimeout(int transactionTimeout)

Specify the transaction timeout, if any.

Default is -1: rely on the transaction manager's default timeout. Specify a concrete timeout to restrict the maximum duration of each endpoint invocation.

isDeliveryTransacted

public boolean isDeliveryTransacted(java.lang.reflect.Method method)
                             throws java.lang.NoSuchMethodException

This implementation returns true if a transaction manager has been specified; false otherwise.

Throws:

java.lang.NoSuchMethodException

createEndpoint

public MessageEndpoint createEndpoint(javax.transaction.xa.XAResource xaResource)
                               throws UnavailableException

The standard JCA 1.5 version of createEndpoint.

This implementation delegates to createEndpointInternal(), initializing the endpoint's XAResource before the endpoint gets invoked.

Throws:

UnavailableException

createEndpoint

public MessageEndpoint createEndpoint(javax.transaction.xa.XAResource xaResource,
                                      long timeout)
                               throws UnavailableException

The alternative JCA 1.6 version of createEndpoint.

This implementation delegates to createEndpointInternal(), ignoring the specified timeout. It is only here for JCA 1.6 compliance.

Throws:

UnavailableException

createEndpointInternal

protected abstract AbstractMessageEndpointFactory.AbstractMessageEndpoint createEndpointInternal()
                                                                                          throws UnavailableException

Create the actual endpoint instance, as a subclass of the AbstractMessageEndpointFactory.AbstractMessageEndpoint inner class of this factory.

Returns:

the actual endpoint instance (never null)

Throws:

UnavailableException - if no endpoint is available at present
