Hi What is your ESB version?

Submitted by indika on June 16, 2009 - 23:37.
Hi What is your ESB version? …JMS transport code seems somewhat old. If you are using new code, exception needs to be more descriptive. This is happened when the object returns from the JNDI lookup using the value of the ‘transport.jms.ConnectionFactoryJNDIName’ is not an instance of javax.jms.ConnectionFactory or returned naming Reference (java naming) has the name of the factory class which may not be in classpath or is not an instance of javax.jms.ConnectionFactory.

Hi Indika, The ESB version is 2.0.2. I notice the following statement in the logs when ESB starts up.  ERROR BaseUtils JNDI lookup of name TopicConnectionFactory returned a org.apache.activemq.ActiveMQConnectionFactory while a interface javax.jms.ConnectionFactory was expected I uncommented the code that was there was jms as part of the download. Can you please help me on how I solve this. Regards. Ravi.

The issue is solved with replacing the jars of Active MQ 5.2 in ESB. Can you please guide me to how AMQP can be configured in ESB. Thanks Ravi.
