What is JMS and MQ?

Asked by: Aisha Clark

The JMS specification defines a set of interfaces that applications can use to perform messaging operations. From IBM MQ 8.0, the product supports the JMS 2.0 version of the JMS standard. This implementation offers all the features of the classic API but requires fewer interfaces and is simpler to use.

What is difference between MQ and JMS?

JMS is the specification provided by Sun for messaging. MQ Queue is the IBM’s implementation of JMS. Similary JBoss has its own implementation. JMS Queue is the generic term.

What is JMS in IBM MQ?

JMS stands for Java Message Service. JMS is a standard that defines how you can access enterprise messaging systems from Java programs. The JMS API is implemented by messaging service providers like IBM MQ to allow JMS client applications to access the provider’s messaging service.

How does JMS work with MQ?

Point-to-Point Messaging is one of the two messaging concepts supported by JMS. With this type of messaging, a message is sent to a queue, which is hosted by the messaging system. In WebSphere MQ, queues are defined on queue managers.

What is MQ used for?

The main use of IBM MQ is to send or exchange messages. One application puts a message on a queue on one computer, and another application gets the same message from another queue on a different computer.

Is JMS an MQ?

IBM® MQ classes for JMS is the JMS provider that is supplied with IBM MQ. IBM MQ classes for JMS implements the interfaces defined in the javax. jms package, and also provides two sets of extensions to the JMS API.

What is MQ in Java?

An IBM MQ classes for Java application can connect to any supported queue manager by using client mode. To connect to a queue manager in client mode, an IBM MQ classes for Java application can run on the same system on which the queue manager is running, or on a different system.

Does IBM MQ use JMS?

From IBM MQ 8.0, IBM MQ supports the JMS 2.0 version of the JMS standard. This implementation offers all the features of the classic API but requires fewer interfaces and is simpler to use. For more information, see JMS model and the JMS 2.0 specification at Java.net.

What is JMS and how it works?

JMS (Java Message Service) is an API that provides the facility to create, send and read messages. It provides loosely coupled, reliable and asynchronous communication. JMS is also known as a messaging service.

Why do we need JMS?

The Java Message Service (JMS) was designed to make it easy to develop business applications that asynchronously send and receive business data and events. It defines a common enterprise messaging API that is designed to be easily and efficiently supported by a wide range of enterprise messaging products.

Is MQ an API?

MQ has a number of APIs that applications written in different languages can use. Click through the Languages, Wire Formats and APIs slides for info on how they are connected. The Message Queue Interface or MQI is the interface that allows the most comprehensive access to MQ objects for applications.

What is MQ process?

The process definition object defines an application that starts in response to a trigger event on an IBM® MQ queue manager. The process definition attributes include the application ID, the application type, and data specific to the application.

Is MQ a protocol?

The MQ protocol is an outbound/active protocol that can monitor multiple message queues, up to a maximum of 50 per log source.

Is JMS a protocol?

JMS is an API and AMQP is a protocol. JMS, back then when it was defined, actually didn’t force a protocol between the JMS client and the JMS messaging server. The JMS client, which implements the JMS API can use whatever protocol to communicate against the JMS server.

Does MQ use TCP?

Depending on your client and server platforms, there are up to four types of transmission protocol for MQI channels: TCP/IP.
Types of transmission protocol for MQI channels.
