Example: Monitor a Queue on a WebLogic Application Server

This example continuously monitors the queue named Queue (residing on WebLogic) for messages matching the filter criteria. The consumed messages from the queue are stored in the file /export/home/user1/outputfile1. The service provider's URL is t3://172.24.0.0:7001, where 172.24.0.0 is the IP address of the WebLogic Application server and 7001 is the ORB port.
