/**
 * 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); * *

If the specified {@code CompletionListener} is not null then subsequent calls to {@code send} will be * 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}. * @return this {@code JMSProducer} * * @throws JMSRuntimeException if an internal error occurs * * @see jakarta.jms.JMSProducer#getAsync * @see jakarta.jms.CompletionListener */ JMSProducer setAsync(CompletionListener completionListener); /** * If subsequent calls to {@code send} on this {@code JMSProducer} object have been configured to be asynchronous then * this method returns the {@code CompletionListener} that has previously been configured.

* A client can use the {@code JMSCorrelationID} header field to link one message with another. A typical use is to link * a response message with its request message. * *

* {@code JMSCorrelationID} can hold one of the following: *

    *
  • A provider-specific message ID *
  • An application-specific {@code String} *
  • A provider-native {@code byte[]} value *
* *

* Since each message sent by a Jakarta Messaging provider is assigned a message ID value, it is convenient to link messages via * message ID. All message ID values must start with the {@code 'ID:'} prefix. * *

* In some cases, an application (made up of several clients) needs to use an application-specific value for linking * messages. For instance, an application may use {@code JMSCorrelationID} to hold a value referencing some external * information. Application-specified values must not start with the {@code 'ID:'} prefix; this is reserved for * provider-generated message ID values. * *

* If a provider supports the native concept of correlation ID, a Jakarta Messaging client may need to assign specific * {@code JMSCorrelationID} values to match those expected by clients that do not use the Jakarta Messaging API.

* Some Jakarta Messaging providers use a message repository that contains the definitions of messages sent by applications. The * {@code JMSType} header field may reference a message's definition in the provider's repository. * *

* The Jakarta Messaging API does not define a standard message definition repository, nor does it define a naming policy for the * definitions it contains. * *

* Some messaging systems require that a message type definition for each application message be created and that each * message specify its type.
