JMS Queue
Note:  For general information about Queue Steps, see Queue Step.
The JMS Queue component facilitates interaction with Java Message Service (JMS) compliant message brokers. The supported JMS queue component versions are 2.0.0 and 3.0.0.
The JMS Queue 3.0.0 differs from version 2.0.0 in that it provides support for durable topic subscriptions and you can set the JMSPriority header when sending messages.
Note:  The JMS 1.0.0 component is deprecated.
Use the following information to migrate from JMS 1.0.0 to the currently supported versions.

Make sure to start your message ID value with the ID prefix.
Enter any of the following:
Provider-specific message ID

Note:  A Java properties file is a simple text file containing a set of property/value pairs. Each property and value is on a separate line. The property name and value are separated by an equal sign (=). For example, a properties file that contains configuration properties for an ActiveMQ connection will look similar to the following:
java.naming.factory.initial=org.apache.activemq.jndi.ActiveMQInitialContextFactory
javax.jms.connectionfactory=ConnectionFactory
java.naming.provider.url=tcp://myhost:61616
