<div class="block">A <code>JMSProducer</code> is a simple object used to send messages on behalf of a <code>JMSContext</code>. An instance of
<code>JMSProducer</code> is created by calling the <code>createProducer</code> method on a <code>JMSContext</code>. It provides
various <code>send</code> 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.
<p>
Message send options may be specified using one or more of the following methods: <code>setDeliveryMode</code>,
<code>setPriority</code>, <code>setTimeToLive</code>, <code>setDeliveryDelay</code>, <code>setDisableMessageTimestamp</code>,
<code>setDisableMessageID</code> and <code>setAsync</code>.
<p>
Message properties may be may be specified using one or more of nine <code>setProperty</code> methods. Any message
properties set using these methods will override any message properties that have been set directly on the message.
<p>
Message headers may be specified using one or more of the following methods: <code>setJMSCorrelationID</code>,
<code>setJMSCorrelationIDAsBytes</code>, <code>setJMSType</code> or <code>setJMSReplyTo</code>. Any message headers set using these
methods will override any message headers that have been set directly on the message.
<p>
All the above methods return the <code>JMSProducer</code> to allow method calls to be chained together, allowing a fluid
programming style. For example:
<p>
<tt>context.createProducer().setDeliveryMode(DeliveryMode.NON_PERSISTENT).setTimeToLive(1000).send(destination, message);</tt>
<p>
Instances of <code>JMSProducer</code> 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</code> method.</div>

<pre><a href="../../javax/jms/JMSProducer.html" title="interface in javax.jms">JMSProducer</a>&nbsp;setAsync(<a href="../../javax/jms/CompletionListener.html" title="interface in javax.jms">CompletionListener</a>&nbsp;completionListener)</pre>
<div class="block">Specifies whether subsequent calls to <code>send</code> on this <code>JMSProducer</code> object should be synchronous or
asynchronous. If the specified <code>CompletionListener</code> is not null then subsequent calls to <code>send</code> will be
asynchronous. If the specified <code>CompletionListener</code> is null then subsequent calls to <code>send</code> will be
synchronous. Calls to <code>send</code> are synchronous by default.
<p>
If a call to <code>send</code> is asynchronous then part of the work involved in sending the message will be performed in
a separate thread and the specified <tt>CompletionListener</tt> will be notified when the operation has completed.
<p>
When the message has been successfully sent the JMS provider invokes the callback method <tt>onCompletion</tt> on the
<tt>CompletionListener</tt> 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.
<p>
The following information is intended to give an indication of how an asynchronous send would typically be
implemented.
<p>
In some JMS providers, a normal synchronous send involves sending the message to a remote JMS 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 JMS server and then returning without waiting for an
acknowledgement. When the acknowledgement is received, the JMS provider would notify the application by invoking the
<tt>onCompletion</tt> method on the application-specified <tt>CompletionListener</tt> object. If for some reason the
acknowledgement is not received the JMS provider would notify the application by invoking the
<tt>CompletionListener</tt>'s <tt>onException</tt> method.
<p>
In those cases where the JMS 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 JMS provider would send the message to the remote JMS server and then return without waiting for an
acknowledgement. However the JMS provider would still notify the application that the send had completed by invoking
the <tt>onCompletion</tt> method on the application-specified <tt>CompletionListener</tt> object.
<p>
It is up to the JMS 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:
<p>
<b>Quality of service</b>: 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 <tt>CompletionListener</tt>'s <tt>onCompletion</tt> method. The <tt>CompletionListener</tt>
must not be invoked earlier than this.
<p>
<b>Exceptions</b>: If an exception is encountered during the call to the <tt>send</tt> method then an appropriate
exception should be thrown in the thread that is calling the <tt>send</tt> method. In this case the JMS provider must
not invoke the <tt>CompletionListener</tt>'s <tt>onCompletion</tt> or <tt>onException</tt> method. If an exception is
encountered which cannot be thrown in the thread that is calling the <tt>send</tt> method then the JMS provider must
call the <tt>CompletionListener</tt>'s <tt>onException</tt> method. In both cases if an exception occurs it is
undefined whether or not the message was successfully sent.
<p>
<b>Message order</b>: If the same <tt>JMSContext</tt> is used to send multiple messages then JMS 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.
<p>
<b>Close, commit or rollback</b>: If the <tt>close</tt> method is called on the <tt>JMSContext</tt> then the JMS
provider must block until any incomplete send operations have been completed and all <code>CompletionListener</code>
callbacks have returned before closing the object and returning. If the session is transacted (uses a local
transaction) then when the <tt>JMSContext</tt>'s <tt>commit</tt> or <tt>rollback</tt> method is called the JMS
provider must block until any incomplete send operations have been completed and all <code>CompletionListener</code>
callbacks have returned before performing the commit or rollback. Incomplete sends should be allowed to complete
normally unless an error occurs.
<p>
A <tt>CompletionListener</tt> callback method must not call <tt>close</tt>, <tt>commit</tt> or <tt>rollback</tt> on
its own <tt>JMSContext</tt>. Doing so will cause the <tt>close</tt>, <tt>commit</tt> or <tt>rollback</tt> to throw an
<tt>IllegalStateRuntimeException</tt>.
<p>
<b>Restrictions on usage in Java EE</b> This method must not be used in a Java EE EJB or web container. Doing so may
cause a <code>JMSRuntimeException</code> to be thrown though this is not guaranteed.
<p>
<b>Message headers</b> JMS defines a number of message header fields and message properties which must be set by the
"JMS provider on send". If the send is asynchronous these fields and properties may be accessed on the sending client
only after the <tt>CompletionListener</tt> has been invoked. If the <tt>CompletionListener</tt>'s
<tt>onException</tt> method is called then the state of these message header fields and properties is undefined.
<p>
<b>Restrictions on threading</b>: 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.
<p>
Setting a <tt>CompletionListener</tt> does not cause the session to be dedicated to the thread of control which calls
the <tt>CompletionListener</tt>. The application thread may therefore continue to use the session after performing an
asynchronous send. However the <tt>CompletionListener</tt>'s callback methods must not use the session if an
application thread might be using the session at the same time.
<p>
<b>Use of the <tt>CompletionListener</tt> by the JMS provider</b>: A session will only invoke one
<tt>CompletionListener</tt> callback method at a time. For a given <tt>JMSContext</tt>, callbacks (both
<code>onCompletion</code> and <code>onException</code>) will be performed in the same order as the corresponding calls to the
<tt>send</tt> method. A JMS provider must not invoke the <tt>CompletionListener</tt> from the thread that is calling
the <tt>send</tt> method.
<p>
<b>Restrictions on the use of the Message object</b>: Applications which perform an asynchronous send must take
account of the restriction that a <tt>Message</tt> object is designed to be accessed by one logical thread of control
at a time and does not support concurrent use.
<p>
After the <tt>send</tt> method has returned, the application must not attempt to read the headers, properties or body
of the <tt>Message</tt> object until the <tt>CompletionListener</tt>'s <tt>onCompletion</tt> or <tt>onException</tt>
method has been called. This is because the JMS provider may be modifying the <tt>Message</tt> object in another
thread during this time. The JMS provider may throw an <tt>JMSException</tt> if the application attempts to access or
modify the <tt>Message</tt> object after the <tt>send</tt> method has returned and before the
<tt>CompletionListener</tt> has been invoked. If the JMS provider does not throw an exception then the behaviour is
undefined.</div>

<p>
This will override any <code>JMSCorrelationID</code> header value that is already set on the message being sent.
<p>
A client can use the <code>JMSCorrelationID</code> header field to link one message with another. A typical use is to link
a response message with its request message.
<p>
<code>JMSCorrelationID</code> can hold one of the following:
<ul>
<li>A provider-specific message ID
<li>An application-specific <code>String</code>
<li>A provider-native <code>byte[]</code> value
</ul>
<p>
Since each message sent by a JMS 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:'</code> prefix.
<p>
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</code> to hold a value referencing some external
information. Application-specified values must not start with the <code>'ID:'</code> prefix; this is reserved for
provider-generated message ID values.
<p>
If a provider supports the native concept of correlation ID, a JMS client may need to assign specific
<code>JMSCorrelationID</code> values to match those expected by clients that do not use the JMS API. A <code>byte[]</code>
value is used for this purpose. JMS providers without native correlation ID values are not required to support

This will override any <code>JMSType</code> header value that is already set on the message being sent.
<p>
Some JMS providers use a message repository that contains the definitions of messages sent by applications. The
<code>JMSType</code> header field may reference a message's definition in the provider's repository.
<p>
The JMS API does not define a standard message definition repository, nor does it define a naming policy for the
definitions it contains.
<p>
Some messaging systems require that a message type definition for each application message be created and that each
message specify its type. In order to work with such JMS providers, JMS clients should assign a value to
<code>JMSType</code>, whether the application makes use of it or not. This ensures that the field is properly set for
those providers that require it.
<p>
To ensure portability, JMS clients should use symbolic values for <code>JMSType</code> that can be configured at
installation time to the values defined in the current provider's message repository. If string literals are used,
they may not be valid type names for some JMS providers.</div>

Messages sent with a null <code>JMSReplyTo</code> value may be a notification of some event, or they may just be some data

Messages with a <code>JMSReplyTo</code> value typically expect a response. A response is optional; it is up to the client
