HI , I need info on MQ JMS , the existing scenario is like request/reply , we have two servers , requesting application is running on first server and provider application is running on second server. in the present set up we installed MQ Server on both systems, we are using MQ - JMS to publish the message to the queue, we created Queue connection factories and generated binding to publish a message to the queue in first server, my question is, can we use MQ Client instead of MQ server at requesting application side to publish a message directly to the local queue at Provider application MQ Server with out changing the Java code and binding files

Client uses different libs & jars. AFAIK you'd need to change the QCF from bindings to client, but that's AFAIK & it's not very far with Java.
Aside from that, there's no difference between a client putting to a local queue and a bound application putting to a local queue unless you're using XA transactions.

Thanks for your reply Victor , but in one of the document I read like To use the bindings connection, IBM WebSphere MQ JMS classes must be installed on the IBM WebSphere MQ server
can you suggest me me other option to uninstall MQ Server at requesting application and to use only MQ Client with major changes at requesting application side

Absolutely yes. As I said, you must change from bindings to client to use the client, which is your only option if MQ server is not installed on the box. Bindings is only possible to a local queue manager.

If you have no MQ server at the requesting side you have no queue manager at the requesting side & your options become a little limited.....

Yes, as long as there is an MQServer somewhere, you can publish/subscribe between any two JMS applications. Those apps don't have to establish bindings connections at all, they can run on any machine.
They should always have the MQ Client installed on the same machine though.
And they need to use a QCF that defines a client connection.
And they cna't do XA if they are using the regular client.
The only thing you would need to change if you have a JMS app that connects using bindings that you want to use client is a) the MQ software, and b) the QCF.
