Andreas Veithen commented on SYNAPSE-369:
-----------------------------------------
Tanmay,
I think that the conclusion is that since the dispatching mechanism shows
problems with both Active MQ and Sonic MQ, it is flawed and needs to be
corrected (even if one can argue that it is because the JMS provider returns
inconsistent information). I believe that we should eliminate the
serviceDestinationNameMapping by having one JMSMessageReceiver instance per
service as described above. But maybe I miss something and there is a good
reason for the existence of serviceDestinationNameMapping.
Asankha,
Can you check my analysis and evaluate the proposed solution?

> Project: Synapse
> Issue Type: Bug
> Components: Transports
> Affects Versions: 1.1.1, 1.2
> Environment: Windows XP, JDK 1.6, Sonic MQ 7.5.1
> Reporter: Tanmay saha
> Original Estimate: 1344h

> This is a new issue. I am running 2 instances of Synapse-1.1.1 or
> Synapse-1.2. Deployed a Proxy over JMS in both instances. Goal is to make
> sure that when a JNDI Topic Entry is created in Sonic MQ with [[groupprefix]]
> in front of the actual topic (for example "[[grpsharedsubs]]TopicXA" ), at a
> time one Synapse instance will receive message from Sonic MQ. But Synapse
> throws some error. I ran a similar test by uisng a plain java jms client,
> which works fine in shared subscription mode. I have all the sonic required
> jars in Synapse\lib folder. The associated configurations are attached here
> 1) JNDI Lookup name in Sonic MQ
> 2) JMSTransport config in axis2.xml
> 3) Proxy config in Synapse
> 4) JMS Transport config in Synapse
> 5) SynapseError log.
