The PowerCenter Integration Service connects to the Java Naming and Directory Interface (JNDI) server to determine connection information for the JMS provider that is the source or target for the JMS message data. After the PowerCenter Integration Service determines the connection information, it connects to the JMS provider to read or write JMS messages.

The PowerCenter Integration Service can read or write messages based on the message domain. It can read and write JMS messages according to the message topic. Or, it can read messages from a JMS provider queue and write messages to a JMS provider queue.
