Scenario

A Spring Boot application using ActiveMQ with @JmsListener suddenly stops receiving messages after running for a while. No errors in logs, and the queue keeps growing, but the consumers seem idle.

Setup

• ActiveMQConnectionFactory was used.

• The queue (myQueue) was filling up.

• Restarting the app temporarily fixed the issue.

Investigation

1. Checked ActiveMQ Monitoring (Web Console)

   • Messages were enqueued but not dequeued.

   • Consumers were still active, but not processing.

2. Thread Dump Analysis

   • Found that listener threads were stuck in a waiting state.

   • The problem only occurred under high load.

3. Checked JMS Acknowledgment Mode

   • Default AUTO_ACKNOWLEDGE was used.

   • Suspected an issue with message acknowledgment.

4. Enabled Debug Logging

   • Added:

     logging.level.org.springframework.jms=DEBUG

   • Found repeated logs like:

     JmsListenerEndpointContainer#0-1 received message, but no further processing

   • This hinted at connection issues.

5. Tested with a Different Message Broker

   • Using Artemis JMS instead of ActiveMQ resolved the issue.

   • Indicated that it was broker-specific.

Root Cause

ActiveMQ’s TCP connection was silently dropped, but the JMS client did not detect it.

• When the connection is lost, DefaultMessageListenerContainer doesn’t always recover properly.

• ActiveMQ does not always notify clients of broken connections.

• No exceptions were thrown because the connection was technically “alive” but non-functional.

Fix

1. Enabled keepAlive in ActiveMQ connection

   ActiveMQConnectionFactory factory = new ActiveMQConnectionFactory(); factory.setUseKeepAlive(true); factory.setOptimizeAcknowledge(true); return factory;

2. Forced Reconnection with Exception Listener

   • Implemented:

     factory.setExceptionListener(exception -> { log.error("JMS Exception occurred, reconnecting...", exception); restartJmsListener(); });

   • This ensured that if a connection was dropped, the listener restarted.

3. Switched to DefaultJmsListenerContainerFactory with DMLC

   • SimpleMessageListenerContainer was less reliable in handling reconnections.

   • New Configuration:

     @Bean public DefaultJmsListenerContainerFactory jmsListenerContainerFactory( ConnectionFactory connectionFactory) { DefaultJmsListenerContainerFactory factory = new DefaultJmsListenerContainerFactory(); factory.setConnectionFactory(connectionFactory); factory.setSessionTransacted(true); factory.setErrorHandler(t -> log.error("JMS Listener error", t)); return factory; }

Final Outcome

✅ After applying these fixes, the issue never reoccurred.
🚀 The app remained stable even under high load.

Key Takeaways

• Silent disconnections in ActiveMQ can cause message listeners to hang.

• Enable keepAlive and optimizeAcknowledge for reliable connections.

• Use DefaultJmsListenerContainerFactory with DMLC instead of SMLC.

• Implement an ExceptionListener to restart the JMS connection if necessary.

Case

Since a couple of days I have met the following issue on my WebLogic server: one application is deployed on a cluster, which references two nodes. Load-balancing (in Round-Robin) is activated for JMS dispatching.

• Yet, all JMS messages are received only by one node (let’s say “the first”), none is received by the other (let’s say “the second”).
• When the 1st node falls, the 2nd receives the messages.
• When the 1st node is started up again, the 2nd keeps on receving the messages.
• When the 2nd node falls, the 1st receives the messages
• and so on

Fix

In WebLogic console go to JMS Modules. In the table of resources, select the connection factory. Then go to the tab Configuration and Load Balance. Uncheck “Server Affinity Enabled“.

Now it should work.

Many thanks to Jeffrey A. West for his help via Twitter.

Case

I used a RuntimeTest to send a JMS message on a WebLogic application, with native WebLogic hosting of the queues, distributed queues to me more accurate. The test was OK.
I clustered the application. When I execute the same test, I get the following error:

[java][JMSExceptions:045101]The destination name passed to createTopic or createQueue "JONATHAN_LALOU_JMS_DISTRIBUTED_QUEUE" is invalid. If the destination name does not contain a "/" character then it must be the name of a distributed destination that is available in the cluster to which the client is attached. If it does contain a "/" character then the string before the "/" must be the name of a JMSServer or a ".". The string after the "/" is the name of a the desired destination. If the "./" version of the string is used then any destination with the given name on the local WLS server will be returned.[/java]

Fix

Since the message error is rather explicit, I tried to add a slash ('/') or a dot ('.') or both ('./'), but none worked.
To fix the issue, you have to prefix the queue name with the JMS module name and an exclamation mark ('!'), in the RuntimeTest configuration file, eg replace:

[xml]<property name="defaultDestinationName" value="JONATHAN_LALOU_JMS_DISTRIBUTED_QUEUE"/>[/xml]

with:

[xml]<property name="defaultDestinationName" value="JmsWeblogicNatureModule!JONATHAN_LALOU_JMS_DISTRIBUTED_QUEUE"/>[/xml]

Case

I have a Mule workflow, of which outbound is a <jms:outbound-endpoint>. The destination queue is hosted on MQ Series and accessed through WebLogic 10.3.3 bridge.

I get the following error:

MQJMS3000: failed to create a temporary queue from SYSTEM.DEFAULT.MODEL.QUEUE

Explanation

A similar issue is described here on Mule support forum. Richard Swart wrote:

This not really mule specific error but an MQ authorization error. The QueueSession.createTemporaryQueue method needs access to the model queue that is defined in the QueueConnectionFactory temporaryModel field (by default this is SYSTEM.DEFAULT.MODEL.QUEUE).

Quick Fix

To fix the issue: on MQ server side, grant visibility to client applications on the default SYSTEM.DEFAULT.MODEL.QUEUE

Abstract

You have a non-clustered installation, on the host with DNS name jonathanDevDesktop, with an admin (port: 7001), a muletier (port: 7003) and a webtier (port: 7005) instances.
You need set your muletier as a clustered installation, with two nodes, on the same server. The second node will dedeployed on port 7007.

We assume you have a configured JMS Modules (in our case: JmsMqModule, even though the bridge between WebLogic and MQ has no impact here).

Process

Batches

• Copy $DOMAINS\jonathanApplication\start-muletier-server.bat" as $DOMAINS\jonathanApplication\start-muletier-server-2.bat"
• Edit it:
  • Possibly, modify the debug port (usually: 5006)
  • Replace the line

    call "%DOMAIN_HOME%\bin\startManagedWebLogic.cmd" muletier t3://jonathanDevDesktop:7001

    with

    call "%DOMAIN_HOME%\bin\startManagedWebLogic.cmd" muletier2 t3://jonathanDevDesktop:7001

Second Node Creation

• Following points are not required.
  • Copy the folder %DOMAIN_HOME%\servers\muletier as %DOMAIN_HOME%\servers\muletier2
  • Delete the folders %DOMAIN_HOME%\servers\muletier2\cache and %DOMAIN_HOME%\servers\muletier2\logs
• Stop the server muletier
• On WebLogic console:
  • Servers > New > Server Name: muletier2, Server Listen Port: 7007 > Check Yes, create a new cluster for this server. > Next
  • Name: jonathanApplication.cluster.muletier > Messaging Mode: Multicast, Multicast Address: 239.235.0.4, Multicast Port:5777
  • Clusters > jonathanApplication.cluster.muletier > Configuration > Servers > Select a server: muletier
  • Clusters > jonathanApplication.cluster.muletier > Configuration > Servers > Select a server: muletier2
• Start the instances of muletier and muletier2 in MS-DOS consoles.
• On the WebLogic console:
  • Deployments > jonathanApplication-web (the mule instance) > Targets > check “jonathanApplication.cluster.muletier” and “All servers in the cluster” > Save
• On the muletier2 DOS console, you can see the application is deployed.

JMS Configuration

The deployment of JMS on clustered environment is a little tricky.

• On WebLogic console: JMS Modules > JmsMqModule > Targets > check “jonathanApplication.cluster.muletier” and “All servers in the cluster“
• Even though it is not required, restart your muletiers. Then you can send messages either on port 7003 or 7007, they will be popped and handled the same way.

Abstract

You have an application deployed on WebLogic 10 (used version for this tutorial: 10.3.3). You have to use an external provider for JMS, in our case MQ Series / WebSphere MQ.
The client side is a Mule ESB launched in standalone.

Prerequisites

You have:

• a running WebLogic 10 with an admin instance and an another instance, in our case: Muletier.
• a file file.bindings, used for MQ.

JARs installation

• Stop all your WebLogic 10 running instances.
• Get the JARs from MQ Series folders:
  • providerutil.jar
  • fscontext.jar
  • dhbcore.jar
  • connector.jar
  • commonservices.jar
  • com.ibm.mqjms.jar
  • com.ibm.mq.jar
• Copy them in your domain additional libraries folder (usually: user_projects/domains/jonathanApplication/lib/)
• Start WebLogic 10 admin. A block like this should appear:
  [java]&lt;Oct 15, 2010 12:09:21 PM CEST&gt; &lt;Notice&gt; &lt;WebLogicServer&gt; &lt;BEA-000395&gt; &lt;Following extensions directory contents added to the end of the classpath:
  C:\win32app\bea\user_projects\domains\jonathanApplication\lib\com.ibm.mq.jar;C:\win32app\bea\user_projects\domains\jonathanApplication\lib\com.ibm.mqjms.jar;C:\win32app\bea\user_projects\domains\jonathanApplication\lib\commonservices.jar;C:\win32app\bea\user_projects\domains\jonathanApplication\lib\connector.jar;C:\win32app\bea\user_projects\domains\jonathanApplication\lib\dhbcore.jar;C:\win32app\bea\user_projects\domains\jonathanApplication\lib\fscontext.jar;C:\win32app\bea\
  user_projects\domains\jonathanApplication\lib\providerutil.jar&gt;[/java]

Config

• Get file.bindings, copy it into user_projects/domains/jonathanApplication/config/jms, rename it as .bindings (without any prefix)
• Launch the console, login
• JMS > JMS Modules > Create JMS System Module > Name: JmsMqModule. Leave other fields empty. > Next > target server MuleTier > Finish
• Select JmsMqModule > New > Foreign Server > Name: MQForeignServer > keep check MuleTier > Finish
  • Select MQForeignServer >
    • JNDI Initial Context Factory: replace weblogic.jndi.WLInitialContextFactory with: com.sun.jndi.fscontext.RefFSContextFactory
    • JNDI Connection URL: set the URI of the folder containing the .bindings file, eg: file://c/win32app/bea/user_projects/domains/jonathanApplication/config/jms
  • Tab Connection Factories > New >
    • Name: MQForeignConnectionFactory
    • Local JNDI Name: the JNDI name on WebLogic side, eg: jonathanApplication/jms/connectionFactory/local (convention I could observe: separator on WebLogic: slash '/' ; unlike clients for which the separator in a dot '.')
    • Remote JNDI Name: the JNDI name on MQ side, eg: JONATHAN_APPLICATION.QCF
    • OK
  • Tab Destinations > New >
    • Queue of requests:
      • Name: JONATHAN.APPLICATION.REQUEST
      • Local JNDI Name: JONATHAN.APPLICATION.REQUEST
      • Remote JNDI Name: JONATHAN.APPLICATION.REQUEST
    • Queue of response:
      • Name: JONATHAN.APPLICATION.REPONSE
      • Local JNDI Name: JONATHAN.APPLICATION.REPONSE
      • Remote JNDI Name: JONATHAN.APPLICATION.REPONSE
    • NB: usually, MQ data are upper-cased and Java’s JNDI names are low-cased typed ; anyway (because of Windows not matching case?) here we use uppercase in for both names.

Mule

This part of the tutorial deals with a case of Mule ESB being your client application (sending and/or receiving JMS messages).

• Get the archive wlfullclient.jar (56MB). Alternatively, you can generate it yourself: go to the server/lib directory of your WebLogic installation (usually: C:\win32app\bea\wlserver_10.3\server\lib, and run: java -jar wljarbuilder.jar
• Copy the archive into $MULE_HOME/lib/user
• Copy the seven jars above (providerutil.jar, fscontext.jar, dhbcore.jar, connector.jar, commonservices.jar, com.ibm.mqjms.jar, com.ibm.mq.jar) into the same folder: $MULE_HOME/lib/user
• You can launch the mule. The config file is similar to any other configuration using standard JMS.

Install and Config

• Let’s assume you would like to run OpenJMS and Tomcat on the same server, eg myLocalServer
• Download OpenJMS from this page.
• Unzip the archive, extract it to C:\exe\openjms-0.7.7-beta-1
• Set an environment variable:set OPENJMS_HOME=C:\exe\openjms-0.7.7-beta-1
• Take the archive $OPENJMS_HOME/lib/openjms-tunnel-0.7.7-beta-1.war
  • copy it to: $CATALINA_HOME/webapps
  • rename it as: openjms-tunnel.war
• Edit OPENJMS_HOME/config/openjms.xml:
  • Before the ending tag</connectors>, add the block:

    <Connector scheme="http">
          <ConnectionFactories>
            <ConnectionFactory name="HTTPConnectionFactory"/>
          </ConnectionFactories>
     </Connector>

  • After the ending tag </connectors>, add the block:

    <HttpConfiguration port="3030" bindAll="true"
           webServerHost="myLocalServer" webServerPort="8080"
           servlet="/openjms-tunnel/tunnel"/>

Run applications

• Launch $OPENJMS_HOME/bin/startup.bat. The following output is expected:

• Launch Tomcat. A webapp with path /openjms-tunnel and display name “OpenJMS HTTP tunnel” should appear.

Checks

• • Open Console² or an MS-DOS prompt
  • Go to $OPENJMS/examples/basic

  • Run: build. This will compile all the examples.

Check that OpenJMS is OK:

• • Edit jndi.properties,
    • Comment the property
      java.naming.provider.url

    • Add the line:

      java.naming.provider.url=tcp://myLocalServer:3035

  • Run:
    run Listener queue1

  • Open a second tab
  • Run:
    run Sender queue1 5

    • Expected output in the second tab:

      C:\exe\openjms-0.7.7-beta-1\examples\basic>run Sender queue1 5
      Using OPENJMS_HOME: ..\..
      Using JAVA_HOME:    C:\exe\beaweblo922\jdk150_10

      Sent: Message 1
      Sent: Message 2
      Sent: Message 3
      Sent: Message 4
      Sent: Message 5

    • Expected output in the first tab:

      C:\exe\openjms-0.7.7-beta-1\examples\basic>run Listener queue1
      Using OPENJMS_HOME: C:\exe\openjms-0.7.7-beta-1

      Waiting for messages...
      Press [return] to quit
      Received: Message 1
      Received: Message 2
      Received: Message 3
      Received: Message 4
      Received: Message 5

Check that OpenJMS/Tomcat link is OK:

Manual Check

• • Stop the Listener instance launched sooner
  • Edit jndi.properties,
    • Comment the line
      java.naming.provider.url=tcp://myLocalServer:3035

    • Add the line:

      java.naming.provider.url=http://myLocalServer:8080

      (this is Tomcat manager URL)

  • Run: run Listener queue1

  • Open a second tab
  • Run:
    run Sender queue1 5

  • The expected output are the same as above.

GUI Check

• Stop the Listener instance launched sooner
• Ensure jndi.properties contains the line:

  java.naming.provider.url=http://myLocalServer:8080

• Run: $OPENJMS_HOME/bin/admin.bat

  • A Swing application should start.
  • Go to:
    Actions > Connections > Online

  • The queue queue1 should be followed by a ‘0’.
  • Run: run Sender queue1 50

    • Action > Refresh

    • The queue queue1 should be followed by a ’50’.
  • Run: run Listener queue1

    • Action > Refresh

    • The queue queue1 should be followed by a ‘0’.

Explanation – Fix

The client JVM was in version 1.6, the server was in 1.5.
To fix the issue, the client must be run with Java 1.5.
Possibly, the client may laucnh the JVM with the option -Dsun.lang.ClassLoader.allowArraySyntax=true.

Context

I have to send JMS messages on queues on clustered servers: t3://firstServer:1234 and t3://secondServer:5678.

The destination queues are retrieved in Spring, thanks to a property like:
[xml]&lt;property name=&quot;providerURL&quot; value=&quot;t3://firstServer:1234,t3://secondServer:5678&quot;/&gt;[/xml]

Error:

I receive the following error:

[java]javax.naming.ConfigurationException [Root exception is java.net.MalformedURLException: port expected: t3://firstServer:1234,t3://secondServer:5678][/java]

Explanation and fix:

When you send messages on many queues, you must not repeat the protocol (here: t3://)! Fixing the issue is very simple: you have to remove the second t3:// in Spring property:

[xml]&lt;property name=&quot;providerURL&quot; value=&quot;t3://firstServer:1234,secondServer:5678&quot;/&gt;[/xml]

The issue appears when I try to deploy an EJB sending JMS messages from my Weblogic server, to another one, in another domain.

Fix:

• I have not fixed the issue myself, I gave pieces of advice to the teams in charge of solving them. But I assume following guidelines are OK.
• Indeed there are two issues: one on credentials and another on servers
• Servers need trust each other. More information is available here. I assume trust is granted thanks to the use of certificates.
• On another hand, credentials from my server, it is to say here “myRole” must be accepted by distant Ldap juridiction. I assume that distant EJB environment must something like:
  • distantEnvironment.put(InitialContext.SECURITY_PRINCIPAL, "myRole");

Now it should work!
