I have one central MQSeries 5.2 server. I would like to connect to the server to put and get messages from Java programs that run on other computers. I am planning to use JMS.
MQ Series 5.2 - Using Java page 169 bottom states about limitation on JMS:
"PUTs can use remote queues, but GETs can only be applied to queues on the local queue manager."
On the other hand,
http://www.developer.ibm.com/tech/faq/individual/0,,2:26186,00.html states:
"When using an MQSeries Java or jms client application, it is not necessary to have the MQSeries client component installed. The Java based clients are written in pure Java and make their own tcp/ip calls to the MQSeries queue manager without using JNI to communicate to the MQSeries client."
I intend to install MQSeries SupportPac MA88 but what about the limitation that JMS cannot get messages from a remote queue?
Thanks

What they mean about JMS (or any MQ app for that matter) is that you cannot get messages from a remote queue definition (they are only a "pointer" to another queue and there will never be a message in them) or you cannot messages from QueueB on QueueManagerB if you are connected to QueueManagerA, either running locally on QueueManagerA or client connnected to QueueManagerA.
You need to client connect to QueueManagerB, at which point you can get messages from any local queues on that queue manager, assuming you have the authority. JMS apps can connect to remote queue managers, not just local ones, and thus can get message from those queues.
