Stomp Problem with receiving topic

[Plew]

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

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.

HTH,

Roger

Thank you Roger

the problem is, that I have more describer for one topic, and they want to get all unread messages when they "log in" at the server....

Based on your description of the problem, it sounds to me like a messaging product is not a good fit for your requirements.  Some kind of RSS or Atom server would be well suited.  Producers can publish to the Atom/RSS feed and consumers can get new items for them every time they "log in".

Hi,

what you need is durable subscriber for the topic.

Unfortunately, the best description is here

http://www.nabble.com/stomp-durable-subscriber-td19446909.html

should write a doc for it.

Cheers
