Re: Stomp Problem with receiving topic

by Roger Hoover :: Rate this Message:

I think that's the way topics are supposed to work. As far as I know, you have to be subscribed to the topic in order to get messages that were published to it. You would need to implement a PHP daemon that remains subscribed to the topic.

If you want to pick up messages periodically and you only have one consumer for each message, you can use a queue.

Hi

i've got a problem with Stomp+PHP 5+ActiveMQ 5.2, I'm new to MQ and JMS,
hope you can help me.

I want to output all messages from a subscribed topic with PHP. The problem
is, only the last message wich was sent by an client to the topic is shown
by the subscriber, but I want to receive also the old messages from the
topic and not only the last one. Also the PHP-Script is not working, when
the topic stores old messages, nothing is shown - it's only working when
it's listening and the client send something new to the topic???

I tried this sheet of code for the Subscriber (for sending i used the
ApacheMQ-Bin Webfrontend).

<?php
require_once("Stomp.php");
$con = new Stomp("tcp://192.0.0.101:61613");
$con->connect();
$con->subscribe("/topic/test");
$msg = $con->readFrame();
echo $msg->body."\n";
$con->ack($msg);
$con->disconnect();
?>

So what should i do, to get all the unreceived messages from the topic,
which where send between last subscription an now, without polling all the
time with one script and a neverending loop, i want to poll cyclic with a
script, to get one or more messages from the topic???

greetings
Stefan
