[Messaging, JMS & JBossMQ] - Durable Subscriptions Scenario
by bdamato
I have a need for a JMS queue where messages are durable, but messages sent to the queue would be processed by only one of three possible subscribers. In other words, there would be a single queue into which I drop a message, three other servers would be periodically polling the queue and whichever server first sees the message, that is the server that processes the message, the other servers never know of the message's existence. I tried to create a single durable subscriber, but when I try to connect from multiple servers I get the error: "The login id has an assigned client id 'testsub1', that is already connected to the server!" If I create multiple durable subscribers, then every subscriber would receive the message (which is not what I want).
Is there a way to have the message be durable, but have it only received by one of the three servers?

[JBoss jBPM] - Re: Signalling Option
by victorl
Ronald, I have resolved the problem as follow:
<task-node name="controlar documentacion" signal="never" create-tasks="false">
| <task name="Control de Documentacion">
| <controller></controller>
| </task>
| <event type="node-enter">
| <action class="ar.com.dsv.saslc.seguimiento.workflow.jbpm.handlers.alta.ObtenerTransiciones" name="obtenerNombreTransiciones"></action>
| </event>
| <transition to="examen psicofisico" name="Completo"></transition>
| <transition to="agendar ctrl documentacion" name="No Completo"></transition>
| </task-node>
Thus (in red), task node does not resume the process execution and task is not instanced.
It seen perhaps unusual and an uncommon behavior, but this is that we need.
If you want to comment anything, it will be welcome.
Thank you very much.
Regards
Victor
