Class SensorsJMSPublisher

java.lang.Object
  org.mbari.siam.core.SensorsJMSPublisher

All Implemented Interfaces:

java.util.EventListener, ServiceListener

public class SensorsJMSPublisher
extends java.lang.Object
implements ServiceListener

SensorsJMSPacketPublisher is the interface from SIAM to the SENSORS project's prototype for CyberInfrastructure. This prototype is part of the NSF funded SNMP project - Scripps-NCSA-MBARI Prototype.

This class instantiates one InstrumentProxy for each SIAM device ID that it finds. The InstrumentProxy is in jar file instrument-proxy.jar, which is generated from the sources found in CVS under sensors/sensors-jms.
