|
<<p>HornetQ is a multi protocol broker. It will inspect the initial handshake of clients to determine what protocol to use.</p>
|
|
|
|
|
<p>All you need to do is to connect a client into hornetq's configured port and you should be able connect.</p>
|
|
|
|
|
<p>To run this example simply run the command <literal>mvn verify</literal>, execute the compile.sh script and start the executable called ./hello</p>

|
|
|
<p>You don't need to do anything special to configure the HornetQ server to accept AMQP clients. </p>
|
|
|
|
|
<p>Just for the sake of documentation though we are setting the port of HornetQ on this example as 5672 which is the port qpid have by default. </p>
|
|
|
|
|
<p>This is totally optional and you don't need to follow this convention. You can use any port you chose including HornetQ's 5445 default port</p>
