+     <h1>JMS XA Heuristic Example</h1>
+     <br>
+     <p>This example shows you how to make an XA heuristic decision through JBoss Messageing Management Interface.</p>
+     
+     <p>A heuristic decision is a unilateral decision to commit or rollback an XA transaction branch after it has 
+     been prepared. </p>
+     
+     <p>In this example we simulate a transaction manager to control the transactions. First we create an XASession
+     and enlist it in a transaction through its XAResource. We then send a text message, 'hello' and end/prepare the transaction
+     on the XAResource, but neither commit nor roll back the transaction. Another transaction is created and
+     associated with the same XAResource, and a second message, 'world' is sent on behalf of the second transaction. Again we leave
+     the second transaction in prepare state. 
+     Then we get the MBeanServerConnection object to manipulate the prepared transactions. To illustrate, we roll back the first 
+     transaction but commit the second. This will result in that only the message 'world' is received. </p>
+
+     <p>This example uses JMX to manipulate transactions in a JBoss Messaging Server. For details on JMX facilities with JBoss 
+     Messaging, please look at the JMX Example.</p>
+     
+     <br>
+     <h2>Example step-by-step</h2>
+     <p><i>To run the example, simply type <code>ant</code> from this directory</i></p>
+     <br>
+     <ol>
+        <li>First we need to get an initial context so we can look-up the JMS connection factory and destination objects from JNDI. This initial context will get it's properties from the <code>client-jndi.properties</code> file in the directory <code>../common/config</code></li>
+        <pre>
+           <code>InitialContext initialContext = getContext(0);</code>
