Interface MessageExchangeFactory

public interface MessageExchangeFactory

A message exchange factory is used used to create new instances of MessageExchange. Service consumers use these factories to create message exchanges when initiating a new service request. Message exchange factories are created using the ComponentContext given to the component during its initialization (see ComponentLifeCycle). There are a variety of ways to creating such factories, each of which creates a context that is used to provide some of the default properties of MessageExchange instances created by the factory instances. For example, a factory can be created for a particular endpoint, ensuring that all exchanges created by the factory have that endpoint set as the default endpoint property of the exchange. This allows components to retain factories as a way of aligning internal processing context with the context contained in the factory, ensuring that the exchanges created consistently reflect that context.

Method Detail

createExchange

MessageExchange createExchange(QName serviceName,
                               QName operationName)
                               throws MessagingException

Creates a new MessageExchange instance used to initiate a service invocation. JBI defines a set of four basic message exchange types, corresponding to the predefined in-* WSDL 2.0 Message Exchange Patterns.

Parameters:

serviceName - name of the service to be invoked

operationName - name of the operation to be invoked

Returns:

new message exchange, initialized for invoking the given service and operation

Throws:

MessagingException - if the given service or operation are not registered with the NMR or the factory was created for a particular interface, and the given serviceName does not implement that interface.

createExchange

MessageExchange createExchange(URI pattern)
                               throws MessagingException

Creates a new MessageExchange instance used to initiate a service invocation. JBI defines a set of eight fundamental message exchange types which are created using binding and engine delivery channels. This base method is provided for extensibility, to satisfy the need for vendor-specific message exchange patterns. The registration and administration of these patterns is not addressed by JBI.

Parameters:

pattern - message exchange pattern

Returns:

new message exchange

Throws:

MessagingException - specified pattern is not registered to a message exchange type

createInOnlyExchange

InOnly createInOnlyExchange()
                            throws MessagingException

Convenience method that creates an In-Only message exchange.

Returns:

new In-Only message exchange

Throws:

MessagingException - failed to create exchange

createInOptionalOutExchange

InOptionalOut createInOptionalOutExchange()
                                          throws MessagingException

Convenience method that creates an In-Optional-Out message exchange.

Returns:

new In-Optional-Out message exchange

Throws:

MessagingException - failed to create exchange

createInOutExchange

InOut createInOutExchange()
                          throws MessagingException

Convenience method that creates an In-Out message exchange.

Returns:

new In-Out message exchange

Throws:

MessagingException - failed to create exchange

createRobustInOnlyExchange

RobustInOnly createRobustInOnlyExchange()
                                        throws MessagingException

Convenience method that creates an Robust-In-Only message exchange.

Returns:

new Robust-In-Only message exchange

Throws:

MessagingException - failed to create exchange
