<div class="jive-rendered-content"><p><span>I'm looking at adding durable subscriptions for the JMS listeners ala </span><a class="jive-link-external-small" href="https://jira.jboss.org/browse/JBESB-1890" target="_blank">https://jira.jboss.org/browse/JBESB-1890</a></p><p style="min-height: 8pt; height: 8pt; padding: 0px;"> </p><p>What I have at the moment results in a config like the following (note the <em>durableSubscriptionName</em> attribute):</p><p style="min-height: 8pt; height: 8pt; padding: 0px;"> </p><pre class="jive-pre"><code class="jive-code jive-xml"><span class="jive-xml-tag"><jms-listener name="JMS-Gateway" busidref="quickstart-topic" is-gateway="true" durableSubscriptionName="quickTopic_service2" /></span>
</code></pre><p style="min-height: 8pt; height: 8pt; padding: 0px;"> </p><p>So... at the moment it's not actually on the <jms-message-fileter> config as per the JIRA.  I think it needs to be on the listener because each subscriber needs to have a unique subscription name, or you get an exception from the JMS Provider i.e. if you have 2 listeners listening to the same topic and both are durable, they both need to have unique subscription names i.e. it's on a per listener basis.</p><p style="min-height: 8pt; height: 8pt; padding: 0px;"> </p><p>There's also a new (optional) clientId attribute on the jms-listener.  This is needed for durable subs.  It is set on the associated JMS Connection, which means it becomes part of the pool key, so as to have a connection pool per clientId.  If the clientId is not configured on the listener (but <em>durableSubscriptionName</em> is configured), we default to the clientId to the listener name value.</p><p style="min-height: 8pt; height: 8pt; padding: 0px;"> </p><p>Does this seem OK, or am I mising something?</p></div>
