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 s peeds 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="BookInOnePage-DurableSubscriptions">Durable Subscriptions</h4><p>If you wish to use durab le topic subscriptions, you need to specify both <strong><code>clientId</code></strong>  and <strong><code>durableSubscriptionName</code>.

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.

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 identif ier 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 id="BookInOnePage-ConfigurationOptions">Configuration Options</h3><p>You can configure many different properties on the JMS endpoint which map to properties on the <a shape="rect" class="external-link" href="http:/ /camel.apache.org/maven/current/camel-jms/apidocs/org/apache/camel/component/jms/JmsConfiguration.html">JMSConfiguration POJO</a>.</p><div class="confluence-information-macro confluence-information-macro-note"><p class="title">Mapping to Spring JMS</p><span class="aui-icon aui-icon-small aui-iconfont-warning confluence-information-macro-icon"></span><div class="confluence-information-macro-body"><p>Many of these properties map to properties on Spring JMS, which Camel uses for sending and receiving messages.
