/**
* A {@code JMSProducer} is a simple object used to send messages on behalf of a {@code JMSContext}. An instance of
* {@code JMSProducer} is created by calling the {@code createProducer} method on a {@code JMSContext}. It provides
* various {@code send} methods to send a message to a specified destination. It also provides methods to allow message
* send options, message properties and message headers to be specified prior to sending a message or set of messages.
*
*
* Message send options may be specified using one or more of the following methods: {@code setDeliveryMode},
* {@code setPriority}, {@code setTimeToLive}, {@code setDeliveryDelay}, {@code setDisableMessageTimestamp},
* {@code setDisableMessageID} and {@code setAsync}.
*
*
* Message properties may be may be specified using one or more of nine {@code setProperty} methods. Any message
* properties set using these methods will override any message properties that have been set directly on the message.
*
*
* Message headers may be specified using one or more of the following methods: {@code setJMSCorrelationID},
* {@code setJMSCorrelationIDAsBytes}, {@code setJMSType} or {@code setJMSReplyTo}. Any message headers set using these
* methods will override any message headers that have been set directly on the message.
*
*
* All the above methods return the {@code JMSProducer} to allow method calls to be chained together, allowing a fluid
* programming style. For example:
*
*
* context.createProducer().setDeliveryMode(DeliveryMode.NON_PERSISTENT).setTimeToLive(1000).send(destination, message);
*
*
* Instances of {@code JMSProducer} are intended to be lightweight objects which can be created freely and which do not
* consume significant resources. This interface therefore does not provide a {@code close} method.

* Specifies whether subsequent calls to {@code send} on this {@code JMSProducer} object should be synchronous or

* asynchronous. If the specified {@code CompletionListener} is null then subsequent calls to {@code send} will be
* synchronous. Calls to {@code send} are synchronous by default.
*
*
* If a call to {@code send} is asynchronous then part of the work involved in sending the message will be performed in
* a separate thread and the specified CompletionListener will be notified when the operation has completed.
*
*
* When the message has been successfully sent the Jakarta Messaging provider invokes the callback method onCompletion on the
* CompletionListener object. Only when that callback has been invoked can the application be sure that the
* message has been successfully sent with the same degree of confidence as if the send had been synchronous. An
* application which requires this degree of confidence must therefore wait for the callback to be invoked before
* continuing.
*
*
* The following information is intended to give an indication of how an asynchronous send would typically be
* implemented.
*
*
* In some Jakarta Messaging providers, a normal synchronous send involves sending the message to a remote Jakarta Messaging server and then waiting
* for an acknowledgement to be received before returning. It is expected that such a provider would implement an
* asynchronous send by sending the message to the remote Jakarta Messaging server and then returning without waiting for an
* acknowledgement. When the acknowledgement is received, the Jakarta Messaging provider would notify the application by invoking the
* onCompletion method on the application-specified CompletionListener object. If for some reason the
* acknowledgement is not received the Jakarta Messaging provider would notify the application by invoking the
* CompletionListener's onException method.
*
*
* In those cases where the Jakarta Messaging specification permits a lower level of reliability, a normal synchronous send might not
* wait for an acknowledgement. In that case it is expected that an asynchronous send would be similar to a synchronous
* send: the Jakarta Messaging provider would send the message to the remote Jakarta Messaging server and then return without waiting for an
* acknowledgement. However the Jakarta Messaging provider would still notify the application that the send had completed by invoking
* the onCompletion method on the application-specified CompletionListener object.
*
*
* It is up to the Jakarta Messaging provider to decide exactly what is performed in the calling thread and what, if anything, is
* performed asynchronously, so long as it satisfies the requirements given below:
*
*
* Quality of service: After the send operation has completed successfully, which means that the message has been
* successfully sent with the same degree of confidence as if a normal synchronous send had been performed, the JMS
* provider must invoke the CompletionListener's onCompletion method. The CompletionListener
* must not be invoked earlier than this.
*
*
* Exceptions: If an exception is encountered during the call to the send method then an appropriate
* exception should be thrown in the thread that is calling the send method. In this case the Jakarta Messaging provider must
* not invoke the CompletionListener's onCompletion or onException method. If an exception is
* encountered which cannot be thrown in the thread that is calling the send method then the Jakarta Messaging provider must
* call the CompletionListener's onException method. In both cases if an exception occurs it is
* undefined whether or not the message was successfully sent.
*
*
* Message order: If the same JMSContext is used to send multiple messages then Jakarta Messaging message ordering
* requirements must be satisfied. This applies even if a combination of synchronous and asynchronous sends has been
* performed. The application is not required to wait for an asynchronous send to complete before sending the next
* message.
*
*
* Close, commit or rollback: If the close method is called on the JMSContext then the JMS
* provider must block until any incomplete send operations have been completed and all {@code CompletionListener}
* callbacks have returned before closing the object and returning. If the session is transacted (uses a local
* transaction) then when the JMSContext's commit or rollback method is called the JMS
* provider must block until any incomplete send operations have been completed and all {@code CompletionListener}
* callbacks have returned before performing the commit or rollback. Incomplete sends should be allowed to complete
* normally unless an error occurs.
*
*
* A CompletionListener callback method must not call close, commit or rollback on
* its own JMSContext. Doing so will cause the close, commit or rollback to throw an
* IllegalStateRuntimeException.
*
*
* Restrictions on usage in Jakarta EE This method must not be used in a Jakarta EE EJB or web container. Doing so may
* cause a {@code JMSRuntimeException} to be thrown though this is not guaranteed.
*
*
* Message headers Jakarta Messaging defines a number of message header fields and message properties which must be set by the
* "Jakarta Messaging provider on send". If the send is asynchronous these fields and properties may be accessed on the sending client
* only after the CompletionListener has been invoked. If the CompletionListener's
* onException method is called then the state of these message header fields and properties is undefined.
*
*
* Restrictions on threading: Applications that perform an asynchronous send must confirm to the threading
* restrictions defined in JMS. This means that the session may be used by only one thread at a time.
*
*
* Setting a CompletionListener does not cause the session to be dedicated to the thread of control which calls
* the CompletionListener. The application thread may therefore continue to use the session after performing an
* asynchronous send. However the CompletionListener's callback methods must not use the session if an
* application thread might be using the session at the same time.
*
*
* Use of the CompletionListener by the Jakarta Messaging provider: A session will only invoke one
* CompletionListener callback method at a time. For a given JMSContext, callbacks (both
* {@code onCompletion} and {@code onException}) will be performed in the same order as the corresponding calls to the
* send method. A Jakarta Messaging provider must not invoke the CompletionListener from the thread that is calling
* the send method.
*
*
* Restrictions on the use of the Message object: Applications which perform an asynchronous send must take
* account of the restriction that a Message object is designed to be accessed by one logical thread of control
* at a time and does not support concurrent use.
*
*
* After the send method has returned, the application must not attempt to read the headers, properties or body
* of the Message object until the CompletionListener's onCompletion or onException
* method has been called. This is because the Jakarta Messaging provider may be modifying the Message object in another
* thread during this time. The Jakarta Messaging provider may throw an JMSException if the application attempts to access or
* modify the Message object after the send method has returned and before the
* CompletionListener has been invoked. If the Jakarta Messaging provider does not throw an exception then the behaviour is
* undefined.
*
* @param completionListener If asynchronous send behaviour is required, this should be set to a
* {@code CompletionListener} to be notified when the send has completed. If synchronous send behaviour is required,
* this should be set to {@code null}.
