class="title">Using ActiveMQ</p><span class="aui-icon aui-icon-small

class="confluence-information-macro-body"><p>The JMS component reuses Spring
2's <code>JmsTemplate</code> for sending messages. This is not ideal for use in
a non-J2EE container and typically requires some caching in the JMS provider to
avoid <a shape="rect" class="external-link"
href="http://activemq.apache.org/jmstemplate-gotchas.html";>poor
performance</a>.</p><p>If you intend to use <a shape="rect"

your Message Broker - which is a good choice as ActiveMQ rocks <img

data-emoticon-name="smile" alt="(smile)"> , then we recommend that you
either:</p><ul><li><p>Use the <a shape="rect" href="activemq.html">ActiveMQ</a>
component, which is already optimized to use ActiveMQ
efficiently</p></li><li><p>Use the <code>PoolingConnectionFactory</code> in
ActiveMQ</p></li></ul></div></div><h4
id="BookComponentAppendix-TransactionsandCacheLevels">Transactions and Cache
Levels</h4><p><span class="confluence-anchor-link"
id="BookComponentAppendix-transactionCacheLevels"></span><br clear="none"> If
you are consuming messages and using transactions
(<strong><code>transacted=true</code></strong>) then the default cache level
can negatively impact performance. If you are using XA transactions then you
cannot cache as it can cause the XA transaction to not work properly.</p><p>If
you are <strong>not</strong> using XA, then you should
consider caching as it speeds up performance, such as setting
<strong><code>cacheLevelName=CACHE_CONSUMER</code></strong>. Through Camel
2.7.x, the default setting for <strong><code>cacheLevelName</code></strong> is
<strong><code>CACHE_CONSUMER</code></strong>. You will need to explicitly set
<strong><code>cacheLevelName=CACHE_NONE</code></strong>. In Camel 2.8 onward,
the default setting for <strong><code>cacheLevelName</code></strong> is
<strong><code>CACHE_AUTO</code></strong>. This default auto detects the mode
and sets the cache level accordingly to:</p><ul
class="alternate"><li><p><code>CACHE_CONSUMER</code>
when <code>transacted=false</code></p></li><li><p><code>CACHE_NONE</code>
when <code>transacted=true</code></p></li></ul><p>So you can say the
default setting is conservative. Consider using
<strong><code>cacheLevelName=CACHE_CONSUMER</code></strong> if you are using
non-XA transactions.</p><h4
id="BookComponentAppendix-DurableSubscriptions">Durable Subscriptions
</h4><p>If you wish to use durable topic subscriptions, you need to specify
both <strong><code>clientId</code></strong>  and
<strong><code>durableSubscriptionName</code>. The value of the
<code>clientId</code></strong> must be unique and can only be used by a single
JMS connection instance in your entire network. You may prefer to use <a
shape="rect" class="external-link"
href="http://activemq.apache.org/virtual-destinations.html";>Virtual Topics</a>
instead to avoid this limitation. More background on durable messaging <a
shape="rect" class="external-link"
href="http://activemq.apache.org/how-do-durable-queues-and-topics-work.html";>here</a>.</p><h4
id="BookComponentAppendix-MessageHeaderMapping">Message Header
Mapping</h4><p>When using message headers, the JMS specification states that
header names must be valid Java identifiers. So try to name your headers to be
valid Java identifiers. One benefit of doing this is that you can then use your
headers inside a JMS Selector (
whose SQL92 syntax mandates Java identifier syntax for headers).</p><p>A
simple strategy for mapping header names is used by default. The strategy is to
replace any dots and hyphens in the header name as shown below and to reverse
the replacement when the header name is restored from a JMS message sent over
the wire. What does this mean? No more losing method names to invoke on a bean
component, no more losing the filename header for the File Component, and so
on.</p><p>The current header name strategy for accepting header names in Camel
is:</p><ul class="alternate"><li><p>Dots are replaced by <code>_DOT_</code> and
the replacement is reversed when Camel consume the
message</p></li><li><p>Hyphen is replaced by <code>_HYPHEN_</code> and the
replacement is reversed when Camel consumes the message</p></li></ul><h3

which map to properties on the <a

id="BookComponentAppendix-Disablingauto-mappingofJMSmessages">Disabling
auto-mapping of JMS messages</h4><p>You can use the <code>mapJmsMessage</code>
option to disable
the auto-mapping above. If disabled, Camel will not try to map the received
JMS message, but instead uses it directly as the payload. This allows you to
avoid the overhead of mapping and let Camel just pass through the JMS message.
For instance, it even allows you to route
<strong><code>javax.jms.ObjectMessage</code></strong> JMS messages with classes
you do <strong>not</strong> have on the classpath.</p><h4
id="BookComponentAppendix-UsingacustomMessageConverter">Using a custom
MessageConverter</h4><p>You can use the <code>messageConverter</code> option to
do the mapping yourself in a Spring
<code>org.springframework.jms.support.converter.MessageConverter</code>
class.</p><p>For example, in the route below we use a custom message converter
when sending a message to the JMS order queue:</p><div class="code panel pdl"
