JMS Transport Reference

JMS (Java Message Service) is a widely-used API for Message Oriented Middleware. It allows communication between different components of a distributed application to be loosely coupled, reliable, and asynchronous.

JMS supports two models for messaging:

  • Queues - Point-to-point
  • Topics - Publish and subscribe

Mule's JMS transport lets you easily send and receive messages to queues and topics for any message service which implements the JMS specification.

Considerations

In the point-to-point or queuing model, a sender posts messages to a particular queue and a receiver reads messages from the queue. Here, the sender knows the destination of the message and posts the message directly to the receiver's queue. It is characterized by the following:

  • Only one consumer gets the message
  • The producer does not have to be running at the time the consumer consumes the message, nor does the consumer need to be running at the time the message is sent
  • Every message successfully processed is acknowledged by the consumer

The publish/subscribe model supports publishing messages to a particular message topic. Subscribers may register interest in receiving messages on a particular message topic. In this model, neither the publisher nor the subscriber know about each other. A good analogy for this is an anonymous bulletin board. The following are characteristics of this model:

  • Multiple consumers (or none) receive the message
  • There is a timing dependency between publishers and subscribers. The publisher has to create a message topic for clients to subscribe.
  • The subscriber has to remain continuously active to receive messages, unless it has established a durable subscription. In that case, messages published while the subscriber is not connected redistribute when it reconnects.

 

Features

  • Supports both versions of the JMS specification: 1.0.2b and 1.1
  • Supports queues and topics, durable or non-durable subscriptions
  • ConnectionFactory and Queues/Topics can be looked up via JNDI
  • Supports local (JMS), distributed (XA), and multi-resource transactions  Enterprise
  • Tested with a variety of JMS providers
  • Vendor-specific configuration available for popular providers

 

WebSphere MQ

Enterprise
Mule Enterprise includes an enhanced transport for WebSphereMQ which is recommended if you are using WebSphereMQ as your JMS provider.

 

Usage

Declaring the Namespace

To use the JMS transport, you must first declare the JMS namespace in the header of your Mule configuration file. You can then configure the JMS connector and endpoints.

JMS Namespace

 

Configuring the Connector

There are several attributes available on the connector, most of which are optional. Refer to the schema documentation below for complete information.

 

Connector Attributes

 

Configuring the ConnectionFactory

One of the most important attributes is connectionFactory-ref. This is a reference to the ConnectionFactory object which will create new connections for your JMS provider. The object must implement the interface javax.jms.ConnectionFactory.

 

ConnectionFactory

There are also a few attributes which allow you to look up the ConnectionFactory from a JNDI Context:

ConnectionFactory from JNDI
JMS Performance

For performance it is important to use the "Caching Connection Strategy" between your JMS Connector and the actual JMS ConnectionFactory implementation. For more information, see "Caching connection factory" below.

 

Configuring the Endpoints

Queues

Topics

By default, Mule's subscription to a topic is non-durable (that is, it only receives messages while connected to the topic). You can make topic subscriptions durable by setting the durable attribute on the connector.

When using a durable subscription, the JMS server requires a durable name to identify each subscriber. By default, Mule generates the durable name in the format mule.<connector name>.<topic name>. If you want to specify the durable name yourself, you can do so using the durableName attribute on the endpoint.

Durable Topic
Number of Consumers

In the case of a topic, the number of consumers on the endpoint is set to one. You can override this by setting numberOfConcurrentTransactedReceivers or numberOfConsumers on the connector.

Transformers

The default transformers applied to JMS endpoints are as follows:
inbound =

JMSMessageToObject

response =

ObjectToJMSMessage

outbound =

ObjectToJMSMessage

These automatically transform to/from the standard JMS message types:

 

Looking Up JMS Objects from JNDI

If you have configured a JNDI context on the connector, you can also look up queues/topics via JNDI using the jndiDestinations attribute. If a queue/topic cannot be found via JNDI, it's created using the existing JMS session unless you also set the forceJndiDestinations attribute.

There are two different ways to configure the JNDI settings:

  1. Using connector properties (deprecated):

  2. Using a JndiNameResolverA JndiNameResolver defines a strategy for lookup objects by name using JNDI. The strategy contains a lookup method that receives a name and returns the object associated to that name.

At the moment, there are two simple implementations of that interface:

SimpleJndiNameResolver: Uses a JNDI context instance to search for the names. That instance is maintained opened during the full lifecycle of the name resolver.

CachedJndiNameResolver: Uses a simple cache in order to store previously resolved names. A JNDI context instance is created for each request that is sent to the JNDI server and then the instance is freed. The cache can be cleaned up restarting the name resolver.

Default JNDI name resolver example: Define the name resolver using the default-jndi-name-resolver tag and then add the appropriate properties to it.

Custom JNDI name resolver example: Define the name resolver using the custom-jndi-name-resolver tag, then add the appropriate property values using the Spring's property format.

Changes in JmsConnector

There are some property changes in the JmsConnector definition. Some properties are now deprecated as they should be defined in a JndiNameResolver and then using that JndiNameResolver in the JmsConnector.

Deprecated properties in JmsConnector:

  • jndiContext
  • jndiInitialFactory
  • jndiProviderUrl
  • jndiProviderProperties-ref

Added property:

  • jndiNameResolver: Sets a proper JndiNameResolver. Can be set using the default-jndi-name-resolver or custom-jndi-name-resolver tags inside the JmsConnector definition.

JMS Selectors

You can set a JMS selector as a filter on an inbound endpoint. The JMS selector simply sets the filter expression on the JMS consumer.

JMS Selector

JMS Header Properties

Once a JMS message is received by Mule, the standard JMS headers such as JMSCorrelationID and JMSRedelivered are made available as properties on the MuleMessage object.

Retrieving JMS Headers

You can access any custom header properties on the message in the same way.

Configuring Transactional Polling

Enterprise

The Enterprise version of the JMS transport can be configured for transactional polling using the TransactedPollingJmsMessageReceiver.

Transactional Polling

❶ Each receiver polls with a 5 second interval

Disable Reply Message

When an incoming message has the replyTo property set, you may wish to disable the automatic reply message on a flow starting with a one-way JMS inbound endpoint. To do so, set the following variable anywhere in your flow to prevent Mule from automatically sending a response.


Example Configurations

Example Configuration

❶ Import the JMS schema namespace


Example Configuration with Transactions

❶ Local JMS transaction


Example Configuration with Exception Strategy

❶ Set exception-pattern="*" to catch all exception types
❷ Implements a dead letter queue for erroneous messages


Vendor-Specific Configuration

Enterprise
Mule Enterprise includes an enhanced transport for WebSphereMQ which is recommended if you are using WebSphereMQ as your JMS provider.

ActiveMQ is also widely-used with Mule and has simplified configuration.

Information for configuring other JMS providers can be found here. Beware that some of this information may be out-of-date.

Reference

Configuration Reference

JMS Transport


The JMS transport provides support for sending messages via JMS queues.

Connector

The connector element configures a generic connector for sending and receiving messages over JMS queues.

Attributes of <connector...>

Name

Type

Required

Default

Description

connectionFactory-ref

string

no

 

Reference to the connection factory, which is required for non-vendor JMS configurations.

redeliveryHandlerFactory-ref

string

no

 

Reference to the redelivery handler.

acknowledgementMode

enumeration

no

AUTO_ACKNOWLEDGE

The acknowledgement mode to use: AUTO_ACKNOWLEDGE, CLIENT_ACKNOWLEDGE, or DUPS_OK_ACKNOWLEDGE.

clientId

string

no

 

The ID of the JMS client.

durable

boolean

no

 

Whether to make all topic subscribers durable.

noLocal

boolean

no

 

If set to true, a subscriber will not receive messages that were published by its own connection.

persistentDelivery

boolean

no

 

If set to true, the JMS provider logs the message to stable storage as it is sent so that it can be recovered if delivery is unsuccessful. A client marks a message as persistent if it feels that the application will have problems if the message is lost in transit. A client marks a message as non-persistent if an occasional lost message is tolerable. Clients use delivery mode to tell a JMS provider how to balance message transport reliability/throughput. Delivery mode only covers the transport of the message to its destination. Retention of a message at the destination until its receipt is acknowledged is not guaranteed by a PERSISTENT delivery mode. Clients should assume that message retention policies are set administratively. Message retention policy governs the reliability of message delivery from destination to message consumer. For example, if a client's message storage space is exhausted, some messages as defined by a site specific message retention policy may be dropped. A message is guaranteed to be delivered once-and-only-once by a JMS Provider if the delivery mode of the messge is persistent and if the destination has a sufficient message retention policy.

honorQosHeaders

boolean

no

 

If set to true, the message's QoS headers are honored. If false (the default), the connector settings override the message headers.

no

 

If set to true, Mule fails when a topic or queue cannot be retrieved from JNDI. If set to false, Mule will create a topic or queue from the JMS session if the JNDI lookup fails.

disableTemporaryReplyToDestinations

boolean

no

 

If this is set to false (the default), when Mule performs request/response calls a temporary destination will automatically be set up to receive a response from the remote JMS call.

embeddedMode

boolean

no

false

Some application servers, like WebSphere AS, don't allow certain methods to be called on JMS objects, effectively limiting available features. Embedded mode tells Mule to avoid those whenever possible. Default is false.

bufferOutput

string

no

queued

Specifies the type of write handler the client will use to send events to the realm. This can be either standard, direct or queued. Unless specified, standard is used. For better latencies use direct, however, this will impact CPU since each write is not buffered but flushed directly. The queued handler will improve CPU and may give better overall throughput since there will be some buffering between client and server. The best of both options is the standard, which attempts to write directly but will back off and buffer the IO flushes when throughput increases and impacts CPU.

syncWrites

boolean

no

false

Sets whether each write to the store will also call sync on the file system to ensure all data is written to the disk, default is false.

queueWindowSize

integer

no

100

When using queues, this specifies the number of messages that the server will send in each block between acknowledgments, default is 100, range is 1 to Integer.MAX_VALUE.

autoAckCount

integer

no

50

When auto acknowledgment mode is selected, rather than ack each event, each nth event will be acknowledged, default is 50, range is 1 to Integer.MAX_VALUE.

enableSharedDurable

boolean

no

false

Allows more than 1 durable subscriber on a topic sharing the same name, with only 1 consuming the events. When the first durable disconnects, the second will take over and so on. Default is false.

randomiseRNames

boolean

no

true

With multiple RNAMEs, the ability to randomize the RNAMEs is useful for load balancing between cluster nodes.

messageThreadPoolSize

integer

no

30

Indicates the maximum number of threads each connection will use to deliver asynchronous events, default is 30, range is 1 to Integer.MAX_VALUE

discOnClusterFailure

enableMultiplexedConnections

boolean

no

false

if this is true, the session will be multiplexed on a single connection else a new socket is created for each session, default is false.

Description

connectionFactory-ref

no

 

Optional reference to the connection factory. A default connection factory is provided for vendor-specific JMS configurations.

redeliveryHandlerFactory-ref

Reference to the redelivery handler.

acknowledgementMode

enumeration

no

AUTO_ACKNOWLEDGE

The acknowledgement mode to use: AUTO_ACKNOWLEDGE, CLIENT_ACKNOWLEDGE, or DUPS_OK_ACKNOWLEDGE.

clientId

string

no

 

The ID of the JMS client.

durable

boolean

no

 

Whether to make all topic subscribers durable.

noLocal

boolean

no

 

If set to true, a subscriber will not receive messages that were published by its own connection.

persistentDelivery

boolean

no

 

If set to true, the JMS provider logs the message to stable storage as it is sent so that it can be recovered if delivery is unsuccessful. A client marks a message as persistent if it feels that the application will have problems if the message is lost in transit. A client marks a message as non-persistent if an occasional lost message is tolerable. Clients use delivery mode to tell a JMS provider how to balance message transport reliability/throughput. Delivery mode only covers the transport of the message to its destination. Retention of a message at the destination until its receipt is acknowledged is not guaranteed by a PERSISTENT delivery mode. Clients should assume that message retention policies are set administratively. Message retention policy governs the reliability of message delivery from destination to message consumer. For example, if a client's message storage space is exhausted, some messages as defined by a site specific message retention policy may be dropped. A message is guaranteed to be delivered once-and-only-once by a JMS Provider if the delivery mode of the messge is persistent and if the destination has a sufficient message retention policy.

Caching connection factory

Allows to configure a connection factory that caches JMS sessions and producers for a single non-XA JMS connection. You must reference a connection factory though the
connectionFactory-ref attribute, and then use this element as the connection factory in the JMS connector.

Notes

The JMS 1.0.2b specification has the limitation of only supporting queues or topics for each ConnectionFactory. If you need both, configure two separate connectors, one that references a QueueConnectionFactory, and another that references a TopicConnectionFactory. You can then use the connector-ref attribute to disambiguate the endpoints.
