MQSeries trigger a CICS transaction

We have a Java program (running in NT) interacting with a mainframe system. MQSeries sits on the mainframe side. When a message arrives on the MQSeries (from java) we want to trigger a mainframe CICS transaction which will get the message and continue the processing. We are unable to trigger the CICS transaction. The CKTI instance for the initiation queue is running. The message does not get or put in either the intitiation or dead letter queue. Would appreciate any help or inputs on triggeringon the mainframe side.

Thanks in advance
