+<p>Apache ActiveMQ Artemis provides a simple bootstrap class,
+<code>org.apache.activemq.integration.spring.SpringJmsBootstrap</code>, for
+integration with Spring. To use it, you configure Apache ActiveMQ Artemis as you always
+would, through its various configuration files like
+<code>broker.xml</code>.</p>
+<p>Here we've specified a <code>javax.jms.ConnectionFactory</code> we want bound to a
+<code>ConnectionFactory</code> entry as well as a queue destination bound to a
+<code>/queue/exampleQueue</code> entry. Using the <code>SpringJmsBootStrap</code> bean will
+automatically populate the Spring context with references to those beans
+so that you can use them. Below is an example Spring JMS bean file
+taking advantage of this feature:</p>
+<pre><code><beans xmlns="http://www.springframework.org/schema/beans"
+ xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
+ xsi:schemaLocation="http://www.springframework.org/schema/beans
+ http://www.springframework.org/schema/beans/spring-beans-3.0.xsd">
+
+ <bean id="EmbeddedJms" class="org.apache.activemq.integration.spring.SpringJmsBootstrap" init-method="start"/>
+
+ <bean id="listener" class="org.apache.activemq.tests.integration.spring.ExampleListener"/>
+
+ <bean id="listenerContainer" class="org.springframework.jms.listener.DefaultMessageListenerContainer">
+ <property name="connectionFactory" ref="ConnectionFactory"/>
+ <property name="destination" ref="/queue/exampleQueue"/>
+ <property name="messageListener" ref="listener"/>
+ </bean>
+</beans>
+</code></pre><p>As you can see, the <code>listenerContainer</code> bean references the components
+defined in the <code>activemq-jms.xml</code> file. The <code>SpringJmsBootstrap</code> class
+extends the EmbeddedJMS class talked about in <a href="embedding-activemq.html">JMS API</a> and the same defaults
+and configuration options apply. Also notice that an <code>init-method</code> must
+be declared with a start value so that the bean's lifecycle is executed.
+See the javadocs for more details on other properties of the bean class.</p>

+ <h1 id="thread-management">Thread management</h1>
+<p>This chapter describes how Apache ActiveMQ Artemis uses and pools threads and how you
+can manage them.</p>
+<p>First we'll discuss how threads are managed and used on the server side,
+then we'll look at the client side.</p>
+<h2 id="server-side-thread-management">Server-Side Thread Management</h2>
+<p>Each Apache ActiveMQ Artemis Server maintains a single thread pool for general use, and
+a scheduled thread pool for scheduled use. A Java scheduled thread pool
+cannot be configured to use a standard thread pool, otherwise we could
+use a single thread pool for both scheduled and non scheduled activity.</p>
+<p>Apache ActiveMQ Artemis will, by default, cap its thread pool
+at three times the number of cores (or hyper-threads) as reported by <code>Runtime.getRuntime().availableProcessors()</code> for processing
+incoming packets. To override this value, you can set the number of
+threads by specifying the parameter <code>nioRemotingThreads</code> in the
+transport configuration. See the <a href="configuring-transports.html">configuring transports</a>
+for more information on this.</p>
+<p>There are also a small number of other places where threads are used
+directly, we'll discuss each in turn.</p>
+<h3 id="server-scheduled-thread-pool">Server Scheduled Thread Pool</h3>
+<p>The server scheduled thread pool is used for most activities on the
+server side that require running periodically or with delays. It maps
+internally to a <code>java.util.concurrent.ScheduledThreadPoolExecutor</code>
+instance.</p>
+<p>The maximum number of thread used by this pool is configure in
+<code>broker.xml</code> with the <code>scheduled-thread-pool-max-size</code>
+parameter. The default value is <code>5</code> threads. A small number of threads
+is usually sufficient for this pool.</p>
+<h3 id="general-purpose-server-thread-pool">General Purpose Server Thread Pool</h3>
+<p>This general purpose thread pool is used for most asynchronous actions
+on the server side. It maps internally to a
+<code>java.util.concurrent.ThreadPoolExecutor</code> instance.</p>
+<p>The maximum number of thread used by this pool is configure in
+<code>broker.xml</code> with the <code>thread-pool-max-size</code> parameter.</p>
+<p>If a value of <code>-1</code> is used this signifies that the thread pool has no
+upper bound and new threads will be created on demand if there are not
+enough threads available to satisfy a request. If activity later
+subsides then threads are timed-out and closed.</p>
+<p>If a value of <code>n</code> where <code>n</code>is a positive integer greater than zero is
+used this signifies that the thread pool is bounded. If more requests
+come in and there are no free threads in the pool and the pool is full
+then requests will block until a thread becomes available. It is
+recommended that a bounded thread pool is used with caution since it can
+lead to dead-lock situations if the upper bound is chosen to be too low.</p>
+<p>The default value for <code>thread-pool-max-size</code> is <code>30</code>.</p>
+<p>See the <a href="http://docs.oracle.com/javase/6/docs/api/java/util/concurrent/ThreadPoolExecutor.htm" target="_blank">J2SE
+javadoc</a>
+for more information on unbounded (cached), and bounded (fixed) thread
+pools.</p>
+<h3 id="expiry-reaper-thread">Expiry Reaper Thread</h3>
+<p>A single thread is also used on the server side to scan for expired
+messages in queues. We cannot use either of the thread pools for this
+since this thread needs to run at its own configurable priority.</p>
+<p>For more information on configuring the reaper, please see <a href="message-expiry.html">message expiry</a>.</p>
+<h3 id="asynchronous-io">Asynchronous IO</h3>
+<p>Asynchronous IO has a thread pool for receiving and dispatching events
+out of the native layer. You will find it on a thread dump with the
+prefix ActiveMQ-AIO-poller-pool. Apache ActiveMQ Artemis uses one thread per opened
+file on the journal (there is usually one).</p>
+<p>There is also a single thread used to invoke writes on libaio. We do
+that to avoid context switching on libaio that would cause performance
+issues. You will find this thread on a thread dump with the prefix
+ActiveMQ-AIO-writer-pool.</p>
+<h2 id="client-side-thread-management">Client-Side Thread Management</h2>
+<p>On the client side, Apache ActiveMQ Artemis maintains a single, "global"
+static scheduled thread pool and a single, "global" static general thread
+pool for use by all clients using the same classloader in that JVM instance.</p>
+<p>The static scheduled thread pool has a maximum size of <code>5</code> threads by
+default. This can be changed using the <code>scheduledThreadPoolMaxSize</code> URI
+parameter.</p>
+<p>The general purpose thread pool has an unbounded maximum size. This is
+changed using the <code>threadPoolMaxSize</code> URL parameter.</p>
+<p>If required Apache ActiveMQ Artemis can also be configured so that each
+<code>ClientSessionFactory</code> instance does not use these "global" static pools but
+instead maintains its own scheduled and general purpose pool. Any
+sessions created from that <code>ClientSessionFactory</code> will use those pools
+instead. This is configured using the <code>useGlobalPools</code> boolean URL parameter.</p>
