Hello All,
This may be a very simple question for folks who are doing this stuff then me who just got into this. I have been reading about JMS and WebSphere MQ in particular and have few basic questions:
1. What is MQ Series? Is it same as WebSphere MQ Series. If so, why we have 2 difference API's. If not, what is the use of one over another
2. What is simple clear difference between JMS and WebSphere MQ APIs. WebSphere MQ Series mentions that I can use JMS API to connect to it, then what is WebSphere MQ API meant for.
3. Sun website says that you can use JMS API to connect to JMS Provider. In this case, a simple Java program can use JMS API to connect to JMS Provider. Are they mentioning about J2EE Application Server as Provider. My understanding is all JMS Provider must have to implement JMS API - correct
This is what my understading is that - WebSphere MQ Series is a product that implements JMS API and in order to connect to it you need the client jars (WebSphere specific). There is nothing related to JMS API that you have to write - but again, I may be wrong
Please help on these question
Thanks a lot |

1.) Yes you have 2 different APIs. The manipulation possibilities are not equal across the 2 different APIs.
2) One is JMS compliant the other isn't.
3) Correct. Not all JMS providers are a J2EE appserver but the J2EE appserver should be able to link to any JMS provider.
To connect you will have to use the JMS API so yes you have to write code. You don't have to write any of the implementation code that's provided in the jars.

JMS is simply a layer which itself uses the underlying MQ API (MQI).
The entire world does not use Java. JMS is Java only.
In Java there is the choice of using MQI or JMS. |

Not really, intercommunication describes communication between MQ series applications. |

Version 1 to 5.2 of the IBM messages product was known as "MQSeries", but from version 5.3 onwards it was rebranded by IBM as "WebSphere MQ", to fit in with the new WebSphere suite of products.
The API is the same. In procedural languages (eg. C, COBOL) the API is called the "MQI".

JMS is an messaging paradigm that can use various providers. MQ has been implemented as one of those providers, to provide a JMS interface into the messaging style of MQ.
The program design style and coding of using JMS and the MQ API (MQI or Java MQ classes) is quite different.

Yes, but you don't need an app server to use the MQ JMS provider.
