Is there any way to extract info like hostname, port and channel from ConnectionFactory obj inside a Java Pgm?
I need to do this because i will need to run a PCF pgm inside this JMS java pgm to clear certain queues, yet, to do so i need the above info to connect to the queue manager. Are there any better way to do this? |

| Try doing an "instanceof" to check whether your QueueConnectionFactory is an instance of MQQueueConnectionFactory. If it is you should be able to cast it to a MQQueueConnectionFactory and retrieve your information from it. |

I am surprised. I would have expected you'd get a message like MQObject in use?
Anyway from JMS I would have thought that if you needed to empty a queue you could have used a destructive receive....
Enjoy

If you want to use reflection then the Jackarta BeanUtils is handy - you can grab an object from somewhere (e.g. JNDI) and not bother about casting. This is useful if you don't want to couple the code to an interface or class.
For example:
Map<String, Object> map = PropertyUtils.describe(bean) ;
or
Object property = PropertyUtils.getProperty("bean", "hostname") ;
It relies on get/set methods following standard bean naming conventions.
I use it in Hermes all the time to create dialogs and so on that can populate a bean for use or render them.
