I understand MQ Queues can be accesses by JMS APIs.
I understand concept of Topic and JMS components in J2EE.
I am using weblogic 7.0. I need some help in linking Topic to the MQ Queue manager and Queue.
I would greatly appreciate your help guys.

With MQ's JMSAdmin, you define a TCF that points to the MQSeries qmgr that you are going to use:
| Code: |
def tcf(myTCF) qmgr(my.qmgr)
|
This will define a TCF that will point to the qmgr and it will also tell MQSeries what to use for the queues for publishing/subscribing. You will also define topics that you will be publishing/subscribing to:
| Code: |
def t(soccer) topic(Sport/Soccer/*)
def t(soccer.latest) topic(Sport/Soccer/Event)
|
The actual queues that JMS will need for publishing/subscribing are created by using the MQJMS_PSQ.mqsc file:
| Code: |
runmqsc my.qmgr < c:\MQSeries\Java\bin\MQJMS_PSQ.mqsc
|
This is very high-level. Did you have a specific question? |

Thanks a Lot.
This really helps me understand connection betn JMS and MQ.
I am trying implement Message Driven Bean to access MQ Queue once a message arrives using MDBs onMessage method. Does this need a different config or the same you mentioned work.
Recommend me if any document explains these specifics.

With WebSphere App Server Enterprise Edition, there are some samples and instructions on what to do. On my system, they are in:
C:\WebSphere\AppServer\Enterprise\samples\messaging\MessagingIntro.html
It takes a couple of hours to walk through the instructions setting things up to run. |

Once you define your Queue and QCF using JMS Admin tool you had established an interface between your App server and MQ series. Now you are free to use JMS/MDB. You have to follow JMS/MDB spec for more details.
Remember MQ provides you messaging framework. In your case you are using MQ Messaging framework insted of Weblogic internal Messaging framework. I am assuming you have 6.0+ weblogic appserver.
