IBM MQ JMS Spring Components

This repository contains code to help to provide Spring developers with easy configuration of the IBM MQ JMS package.

The library contains:

Installation and Usage

The compiled version of this package can be automatically downloaded from Maven Central. For local modifications and building it yourself, see

Spring Boot Applications


repositories {

dependencies {
    compile group: '', name: 'mq-jms-spring-boot-starter', version: 'x.y.z'



Note This repository and the corresponding Maven Central artifact require Spring Boot 2. For Spring Boot 1 compatibility, you can use the previously-released level of the artifact at version 0.0.4.

Design Approach

The approach taken here is to follow the model for JMS applications shown in the Spring Getting Started Guide for JMS. That in turn is based on using the JmsTemplate Framework

Some simple example programs using Spring Boot and JMS interfaces can be found in the samples directory. The program in each subdirectory compiles and executes it. The files in that tree may need modification for your environment.

Essentially what gets configured from this package are a ConnectionFactory which Spring's JmsTemplate implementation exploits to provide a simpler interface, and a MessageListener.

Getting Started

To get started quickly, you can use the default configuration settings in this package along with the IBM MQ for Developers container which runs the server processes.

Default Configuration

The default options have been selected to match the MQ Docker container development configuration.

This means that you can run a queue manager using that Docker environment and connect to it. This script will run the container on a Linux system.

docker run --env LICENSE=accept --env MQ_QMGR_NAME=QM1 \
           --publish 1414:1414 \
           --publish 9443:9443 \
           --detach \

The default attributes are

Connection security

The default userid and password have been chosen for a commonly-used queue manager configuration.

To disable user/password checking entirely, you must set the attribute to an empty value so that the default is not used.

Of course, that level of access must be permitted by your queue manager. The usual CHLAUTH and CONNAUTH rules will apply to assign an identity to the connection.

Configuration of secure connections with TLS are discussed below.

Configuration Options

If you already have a running MQ queue manager that you want to use, then you can easily modify the default configuration to match by providing override values.

The queue manager name is given as


For client connections to a queue manager, you must also have either

  • or

If both the channel and connName are empty, and the CCDTURL is not supplied, then a local queue manager is assumed. The CCDTURL property is taken in preference to the channel and connName. The channel and connName have non-blank defaults, so must be explicitly set to empty strings if you do not wish them to be used.

Optionally you can provide a client id and application name if required.


You will probably also need to set


to override the default values.

For example in an file:

Spring Boot will then create a ConnectionFactory that can then be used to interact with your queue manager.

Option Description Name of queue manager Channel Name for SVRCONN Connection Name, which can be comma-separated list Location of the MQ CCDT file (URL can reference http/ftp location) User Name. Must be set to an empty value to turn off authentication attempts Password ClientId uniquely identifies the app connection for durable subscriptions Application Name used for Uniform Cluster balancing Control authentication mechanism for old queue managers (default true) The prefix to be used to form the name of an MQ dynamic queue The prefix to be used to form the name of an MQ dynamic topic The name of a model queue for creating temporary destinations.

TLS related options

The following options all default to null, but may be used to assist with configuring TLS

Option Description Cipher Suite, sets connectionFactory property WMQConstants.WMQ_SSL_CIPHER_SUITE Cipher Spec, sets connectionFactory property WMQConstants.WMQ_SSL_CIPHER_SPEC Peer Name, sets connectionFactory property WMQConstants.WMQ_SSL_PEER_NAME Sets System property

We also have

Option Description Force FIPS-compliant algorithms to be used (default false) How many bytes to send before resetting the TLS keys

Caching connection factory options

You may want to use the default Spring Caching connection factory with the default Spring JMS properties. This is now the preferred method in Spring for holding JMS objects open, rather than the Pooling options described below.

Option Description
spring.jms.cache.enabled Whether to cache sessions
spring.jms.cache.consumers Whether to cache message consumers
spring.jms.cache.producers Whether to cache message producers
spring.jms.cache.session-cache-size Size of the session cache (per JMS Session type)

Pooled connection factory options

Alternatively you may configure a pooled connection factory by using those properties:

Option Description Enabled Pooled connection factory usage Blocks a connection request when the pool is full. Default is false Blocking period before throwing an exception if the pool is still full Connection idle timeout. Default to 30 seconds Maximum number of pooled connections. Default is 1 Maximum number of pooled sessions. Default is 500 Time to sleep between runs of the idle connection eviction thread. Disable when negative. Default is -1 Whether to use only one anonymous "MessageProducer" instance. Set it to false to create one "MessageProducer" every time one is required

These pooling options make use of the PooledJMS implementation. More documentation on the options can be found here.

JMS Polling Listener Timer configuration

The Spring AbstractPollingMessageListenerContainer interface has a default polling timer of 1 second. This can now be configured with the spring.jms.listener.receiveTimeout property. If the property is not explicitly set, then this MQ Spring Boot component resets the initial timeout value to 30 seconds which has been shown to be more cost-effective. Application code can still set its own preferred value.

Option Description
spring.jms.listener.receiveTimeout How frequently to poll for received messages. Default is 1s. Given as a Duration string: "1m", "60s", "60000" are equivalent

Additional properties

Additional properties that are not in the recognised sets listed here can be put onto the Connection Factory via a map in the external properties definitions. Use the format The CONSTANT_NAME can be either the real string for the property, and will often begin with "XMSC", or it can be the variable as known in the WMQConstants class.

For example, the constant WMQConstants.WMQ_SECURITY_EXIT has the value "XMSC_WMQ_SECURITY_EXIT" and can be written either as or as

There is no error checking on the property name or value. This may help with enabling rarely-used properties and reduce the need for a customizer method in application code. See the KnowledgeCenter for a list of all the currently-recognised properties that may be set on a CF - though note that many are now deprecated.

If the value looks like a number, it is treated as such. You can use hex constants beginning "0X" or decimals for a number. Similarly if the value is TRUE/FALSE then that is processed as a boolean. So you cannot try to set a string property that appears to be an integer. Symbols representing the value of integer attributes cannot be used - the real number must be given.


Spring already has configuration parameters for the use of a JNDI repository with a JMS program. See the Spring documentation for more details.

However this package also enables some simple use of JNDI for Connection definitions (but not Destinations, as they are still always handled by the core Spring classes).

You can set the and attributes to define how the lookup is to be carried out. For example,

If you choose to use this mechanism, all of the other queue manager properties that might be defined in your resource definitions are ignored and not traced in order to avoid confusion. They will instead be picked up from the ConnectionFactory definition in JNDI. The queueManager property is then more accurately used as the ConnectionFactory name used as the lookup. If you are using an LDAP JNDI provider, then the CF name will be modified if necessary to always begin with cn=.

The prefix can be used for any other JNDI-related properties that need to be applied to the Context object. The symbolic name of the field from that Java class can be used. For example,

results in


The MQConnectionFactoryFactory.getJndiContext method is public so you can use it with your own constructed properties object and get access to a JNDI Context object - it might make it easier to work with Destinations if you can reuse the same way of getting directory access.

Logging & Tracing

The package makes use of the logging capabilities within Spring. You can enable tracing of this specific component in your application's properties file by setting Otherwise it uses the standard inheritance of logging configuration from logging.level.rootdownwards.
