Description

I've set create-destinations="false" in my jmsreader.sbconf configuration file. When I attempt to subscribe to an existing topic on the ActiveMQ server, I see the following exception:
 

2013-01-22 10:44:51.504-0500 [TaskRunner] DEBUG InFromJMS - Server Server1 is now connected.
2013-01-22 10:44:51.508-0500 [TaskRunner] DEBUG InFromJMS - Looking up destination MarketData.SYM in JNDI
2013-01-22 10:44:51.514-0500 [TaskRunner] ERROR InFromJMS - Could not find JMS destination MarketData.SYM in JNDI. Cause: Could not find JNDI object MarketData.SYM using settings configured for JMS server Server1: MarketData.SYM
com.streambase.sb.StreamBaseException: Could not find JNDI object MarketData.SYM using settings configured for JMS server Server1: MarketData.SYM

Resolution

For topics that already exist in ActiveMQ, use the prefix 'dynamicTopics/' in the destination name attribute in your jmsreader.sbconf configuration file. For example:
 
<destinations>
<destination name="dynamicTopics/MarketData.SYM"/>
</destinations>


This allows you to locate topics using JNDI without any configuration, as described in the ActiveMQ Help under Apache ActiveMQ > Connectivity > Containers > JNDI Support
