<h1>JMS Clustered Grouping Example</h1>
|
|
|
|
<pre>To run the example, simply type <b>mvn verify</b> from this directory, <br>or <b>mvn -PnoServer verify</b> if you want to start and create the server manually.</pre>
|
|
|
|
<p>This example demonstrates how to ensure strict ordering across a cluster using clustered message grouping</p>
|
|
<p>We create 3 nodes each with a grouping message handler, one with a Local handler and 2 with a Remote handler.</p>
|
|
<p>The local handler acts as an arbitrator for the 2 remote handlers, holding the information on routes and communicating
|
|
the routing info with the remote handlers on the other 2 nodes</p>
|
|
<p>We then send some messages to each node with the same group id set and ensure the same consumer receives all of them</p>
|
|
<p>Here's the relevant snippet from the server configuration that has the local handler</p>
|
|
<pre>
|
|
<code>
|
|
<cluster-connections>
|

<cluster-connection name="my-cluster">
