Hi Guys,
I am new to this forum as well as to MOMs. We have a distributed system and we are using MQ all over the place. Now, we have two other applications which are totally J2EE and I am going the JMS route to write messages from these applications to the remote MQ(IBM) queues.
What all is involved here ? We use weblogic 510sp10 to host the J2EE applications. I can see that weblogic acts like a JMS server and it is supposed to shield the client from the implementation of MQ. This is where my confusion is, where do we configure in weblogic to actually refer to the mq queue ? I hope I do not have to do this in the application as I do not want any code to have mq-specific stuff.
This is a long post, but I hope I have explained my problem well enough for some one to answer.
Thanks,
Raj Yerapotini.

hi rajani ,
let me throw some light on this . weblogic 5 .1 provides jms support . it means that it has its own jms implemenation. Moreover weblogic 5.1 does nto provide interoperability with other leading MOMS such as IBM MQSERIES , TIBCO OR FIORANO.if you have to write applications using mqseries there are 2 ways . no 1 is u can write mq applications using mq base java apis which is properitary to IBM and no 2 is u can use ibm mq jms apis mq jms apis adopts the jms standard . if you use jms apis u can use it across all MOMS adopting the jms standard. now coming to your question
where do we configure in weblogic to actually refer to the mq queue ?
no where . actually In weblogic 5.1 you cant configure weblogic to lietsn to mq queue . why beacuse the JNDI SETTINGS are totally different as they come from different vendor and the jms implementation too . so you cant use weblogic's jms to talk to mq series . rather you can write common messaging utulities in jms by parameterizing the jndi settings and the jms objects names and use it across weblogic and mqseries . i hope this finds u in comfort . if you have any queries hit me a mail @ a_murugan@yahoo.com
cheers,
Murugan |

Murugan,
Thanks for the input. We are using the MQ JMSAdmin in which we are running a program called IVTSetup that actually binds some names into the JNDI tree of weblogic. After that, we are also able to run another program IVTRun that actually writes to the MQ queue.
Now, the only problem is the JNDI binding is transient, i.e., once weblogic is brought down, the JNDI mappings are gone. Is there a way out of this ? I am tempted to pursue putting the MQ queue parameters in weblogic.properties (but I dont know if this is possible).
Thanks,
-Raj.
