Connecting to IBM(Websphere MQ) : Use JMS or Native library?
Hi all,
This is a very basic question, but I need to get the doubt cleared. It would be great if you could clarify..
I want to communicate with an application, which has only IBM(Websphere) MQ interface.
Question: In order to communicate, do I use Connector-MQ(for sending info), or Connector-JMS?
The reason I ask this question is because I read in Websphere MQ Primer ebook as follows:
<<< The native interface is the Message Queue Interface (MQI).
Using a standardized API can add additional flexibility when accessing services through a message queuing infrastructure. This book uses the term standardized API to represent APIs that are not proprietary to an individual product, such as WebSphere MQ.
The following list notes examples of standardized APIs that can be used to access services that are provided through a WebSphere MQ infrastructure:
Java Message Service (JMS), IBM Message Service Client (XMS) >>>
I think the answer is to use "Connector-MQ" here, and not "Connector-JMS", since the application to which I connect, does not specifically provide JMS connection. However, going by explanation I quoted above, since Pega is Java based, and also has JMS connector, does it make JMS connector as a choice?
Sorry if this is too basic, but any help is appreciated..
Version info:
Pega 7.3, IBM MQ 9.0(Windows)

Hi,
You can use either Connect-MQ/Connect-JMS based on the deployment of war file or ear file. For war file deployment go with MQ.

This is the explanation on PDN Help.
<<When the Pega 7 Platform is deployed as an enterprise application, you must use a message-driven bean (MDB) as the listener for message-based service rules (JMS and MQ).
As a result, when Pega 7 Platform is deployed as an enterprise application, although you can use WebSphere MQ as a JMS service provider,
use JMS MDB listeners with JMS service rules, rather than MQ listeners with MQ service rules, >>
It looks like we may have Enterprise application, so must use MDB as Listener with JMS Service rules.
====
Updates : Pega Personal Edition uses Tomcat..
Hence, for PoC, one needs to consider Web application. So MQ Listener and MQ Service rules must be used.
To connect from Pega to IBM MQ, importing of IBM MQ jar files is required. See this link -
(Ignore these jars. They don't seem to be required. - dhbcore.jar, com.ibm.mq.connector.jar)

Hi Sudhakar,
Thanks for the explanation. We are looking at messaging with non-J2EE compliant application, so it looks like we will have to use MQ.
Thanks a lot.
