Standalone server

If you wish to run the JBossESB server on the same machine as JBossAS, then you should look at http://wiki.jboss.org/wiki/Wiki.jsp?page=ConfiguringMultipleJBossInstancesOnOneMachine

JBossESB JMS Providers

The JBossESB supports a number of JMS providers. Currently we have successfully test JBossMQ, ActiveMQ and Websphere MQ Series (version 5.3 and 6.0). There is no reason that any other JMS provider would not work. We simply did not have time to validate more then these three for now.

How can I configure them?

JMSListeners and JMSGateways can be configured to listen to a Queue or Topic. For this you can use the following parameters in their configuration (jbossesb-listener.xml and jbossesb-gateway.xml): jndi-URL, jndi-context-factory, jndi-pkg-prefix, connection-factory, destination-type and destination-name. Furthermore you will need to add the client jms jars of the JMS-provider you want to use to the classpath.

In the following sections we will assume that your JMS provider runs on 'localhost', that the connection-factory is 'ConnectionFactory', that we are listenening to a destination-type 'queue' and that it's name is 'queue/A'.

  1. Each JMSListener and JMSGateway can be configured to use it's own JMS provider, so you can use more then one provider in your deployment.

When using JMS, JBossESB utilizes a connection pool to improve performance. By default the size of this pool is set to 20, but can be over-ridden by setting the org.jboss.soa.esb.jms.connectionPool property in the transports section of the JBossESB configuration file. Likewise, if a session cannot be obtained initially, JBossESB will keep retrying for up to 30 seconds before giving up. This time can be configured using the org.jboss.soa.esb.jms.sessionSleep property.

JBossMQ or JBossMessaging

The settings for JBossMQ and JBossMessaging are identical and you should set the parameters to:






For JBossMQ you should have


In your classpath. Not that this jar is included in jbossall-client.jar, which can be found in lib/ext. For JbossMessaging it should be


While -for now- the JBossMQ is the default JMS provider in JBossAS, you can also use JbossMessaging. To setup JbossMessaging see the screenshot document on our wiki:


JBoss Messaging Clustering configuration

Configuring JBoss Messaging in a clustered setup gives you loadbalancing and failover for JMS.

The file deploy/jboss-messaging.sar/messaging-service.xml contains the configuration for a ServerPeer. JBoss Messaging is serverless which means that the system does not rely on a central server. Every ServerPeer must have a unique id:

<mbean code="org.jboss.jms.server.ServerPeer"




<!-- ServerPeerID -->

<arg type="int" value="1"/>

Specify a unique integer for each ServerPeer in the cluster.

To make destinations distributable one has to set the 'Clustered' attribute to true in the destination definition xml file. Example of defining a clustered destination:





<depends optional-attribute-name="ServerPeer">




<attribute name="Clustered">true</attribute>


The jboss-esb.xml configuration must be updated to use a 'ClusteredConnectionFactory:

<jms-provider name="JBossMessaging"




JBoss Messaging has the ability for queues on one node to pull messages from other nodes when they have exhausted their local messages.

This prevents messages from getting stranded on nodes with slow or no consumers, and balances out message processing across the cluster.

How, if and when messages are pulled from one node to another is determined by the MessagePullPolicy. The default policy never pulls messages from one node to another. Whether you need message redistribution or not depends on your application topology.

To specify that you do want messages to be balanced out across the cluster, update the jboss-messaging.sar/clustered-xxx-persistence-service.xml to uses a ‘MessagePullPolicy’:

<attribute name="MessagePullPolicy">



During development it might be convenient to set the attribute 'GroupName' to a unique name for every developers local machines to avoid creating a cluster containing all developers instances. Note that changing the multicast address and port is also recommended to further separate the clusters. More information about the reason for this can be found here: http://wiki.jboss.org/wiki/Wiki.jsp?page=PromiscuousTraffic


For ActiveMQ you should set the parameters to:






In your classpath you should have



Both jars can be found in lib/ext/jms/activemq. We tested with version 4.1.0-incubator.

Websphere MQ Series

For Websphere MQ Series you should set the parameters to:






  1. Websphere likes all CAPS queue names and no slashes (QUEUEA), and the name of the Queue Manager in MQ should match what the value of 'connection-factory' is (or bind this name to JNDI). In our case we created a Queue Manager named “ConnectionFactory”.

On your classpath you should have



and the client jars:



Please note that the client jars differ between MQ 5.3 and MQ 6.0. However the 6.0 jars should be backward compatible. The jars are not open source, and are therefor not provided by us. You will have to obtain them from your WAS and MQ installs.

Also note that you may get the following exception when running MQ 6.0, which can be fixed by adding the user that runs the jbossesb to the mqm group:

Note that for MQ 6.0:

Message: Unable to get a MQ series Queue Manager or Queue Connection. Reason: failed to create connection --javax.jms. JMSSecurityException: MQJMS2013: invalid security authentication supplied for MQQueueManager

Explanation: There is a problem with user permissions or access.

Tip: Make sure the user accessing MQ Queue Manager is part of the mqm group.

Database Configuration

The ESB uses database for persisting Registry services, and the Message-Store.

Database scripts for each of these can be found under:

Service Registry: ESB_ROOT/install/juddi-registry/sql

Message-Store: ESB_ROOT/services/jbossesb/src/main/resources/message-store-sql

A few database types and their scripts are provided, and you should be able to easily create one for your particular database (if you do, please contribute it back to us).

For the Message-Store you will need to also update the data-source setting properties in the main ESB config file jbossesb-properties.xml. The following are settings you will need to change, based on the connection information appropriate to your environment – these settings are found in the DBSTORE section of the file.

As long as there is script for your database the ESB will auto-create the schema's on startup. By default JBossESB is configured to use a JEE DataSource.

<properties name="dbstore">

<property name="org.jboss.soa.esb.persistence.db.conn.manager" value="org.jboss.soa.esb.persistence.manager.J2eeConnectionManager"/>

<!-- this property is only used if using the j2ee connection manager -->

<property name="org.jboss.soa.esb.persistence.db.datasource.name" value="java:/JBossESBDS"/>


When running from the standalone bootstrapper use:

<properties name="dbstore">

<!-- connection manager type -->

<property name="org.jboss.soa.esb.persistence.db.conn.manager" value="org.jboss.soa.esb.persistence.manager.StandaloneConnectionManager"/>

<property name="org.jboss.soa.esb.persistence.db.conn.manager"

<property name="org.jboss.soa.esb.persistence.db.connection.url" value="jdbc:hsqldb:hsql://localhost:9001/jbossesb"/>

<property name="org.jboss.soa.esb.persistence.db.jdbc.driver" value="org.hsqldb.jdbcDriver"/>

<property name="org.jboss.soa.esb.persistence.db.user" value="sa"/>

<property name="org.jboss.soa.esb.persistence.db.pwd" value=""/>

<property name="org.jboss.soa.esb.persistence.db.pool.initial.size" value="2"/>

<property name="org.jboss.soa.esb.persistence.db.pool.min.size" value="2"/>

<property name="org.jboss.soa.esb.persistence.db.pool.max.size" value="5"/>

<property name="org.jboss.soa.esb.persistence.db.pool.test.table" value="pooltest"/>

<property name="org.jboss.soa.esb.persistence.db.pool.timeout.millis" value="5000"/>

The Service Registry database information is contained in the juddi.properties file. You should consult the Service Registry section of this document for more detailed information on what settings and their values and how they effect the behavior of the ESB.

JBoss server comes with a pre-installed hypersonic database (HSQLDB). The database can only be accessed in the same JVM. The data-source definition can be found in the jbossesb.sar/message-store-ds.xml.

  1. Use of HSQLDB for production is not recommended.

Using a JSR-170 Message Store

JBossESB allows for multiple message store implementations via a plugin-based architecture. As an alternative to the default database message store, a JSR-170 (Java content repository) message store may be used. The JCR implementation included with JBossESB is Apache Jackrabbit. To enable the JCR message store, add the following property to the "core" section of jbossesb-properties.xml in the root of the jboss-esb.sar:

<property name="org.jboss.soa.esb.persistence.base.plugin.jcr"


This adds the JCR plugin to the list of available message stores. The JCR message store can use an existing repository via JNDI or can create a standalone instance locally on the application server. The following list of properties should be added in the "dbstore" section of jbossesb-properties.xml to configure repository access:

<property name="org.jboss.soa.esb.persistence.jcr.jndi.path" value="jcr"/>

<property name="org.jboss.soa.esb.persistence.jcr.username" value="username"/>

<property name="org.jboss.soa.esb.persistence.jcr.password" value="password"/>

<property name="org.jboss.soa.esb.persistence.jcr.root.node.path"


An easy test for whether the JCR message store is configured properly is to add the org.jboss.soa.esb.actions.persistence.StoreJCRMessage action onto an existing service. The action will attempt to store the current message to the JCR store.


At the heart of all JBossESB deployments is the registry. This is fully described elsewhere in the Registry Guide, where configuration information is also discussed. However, it is worth noting the following:

Default ReplyTo EPR

JBossESB uses Endpoint References (EPRs) to address messages to/from services. As described in the Programmers Guide, messages have headers that contain recipient addresses, sequence numbers (for message correlation) and optional addresses for replies, faults etc. Because the recommended interaction pattern for within JBossESB is based on one-way message exchange, responses to messages are not necessarily automatic: it is application dependent as to whether or not a sender expects a response.

As such, a reply address (EPR) is an optional part of the header routing information and applications should be setting this value if necessary. However, in the case where a response is required and the reply EPR (ReplyTo EPR) has not been set, JBossESB supports default values for each type of transport. Some of these ReplyTo defaults require system administrators to configure JBossESB correctly.

ServiceBinding Manager

If you wish to run multiple ESB servers on the same machine, you may want to use JBoss ServiceBinding Manager. The binding manager allows you to centralize port configuration for all of the instances you will be running. The ESB server ships with a sample bindings file in docs/examples/binding-manager/sample-bindings.xml. Chapter Ten of the Jboss appplication server documentation contains instructions on how to set up the ServiceBinding manager. Two notes :

Monitoring and Management

There are a number of options for monitoring and managing your ESB server. Shipping with the ESB are a number of useful JMX MBeans that help administrators monitor the performance of their server.

Under the jboss.esb domain, you should see the following MBean types :

Additionally, jms domain MBeans show statistics for message queues, which is useful information when debugging or determining performance.
