Why am I getting this error message when configuring ActiveMQ to work with JMS Messaging Modular Input Add-on?

[michaeltay]

Hi all, I am relatively new to ActiveMQ and JMS.

I have tried reading all the documentation (http://activemq.apache.org/jndi-support.html) and support forums, but I am still unable to figure out what went wrong.

I am trying to poll from a queue using JMS Messaging Modular Input.

The following was done:
1) Created jndi.properties and placed it (a) as a jar file in $SPLUNK_HOME\etc\apps\jms_ta\bin\lib\ (jndi.properties is in the root) and (b) at apache-activemq-5.13.3\conf

java.naming.factory.initial = org.apache.activemq.jndi.ActiveMQInitialContextFactory
java.naming.provider.url = tcp://192.168.99.2:61616
connectionFactoryNames = connectionFactory
queue.MyQueue = foo.bar

2) Included activemq-all-5.13.3.jar in $SPLUNK_HOME\etc\apps\jms_ta\bin\lib\
3) Configured inputs.conf in launcher app

[jms://queue/:MyQueue]
browse_frequency = -1
browse_mode = all
browse_queue_only = 1
durable = 0
hec_batch_mode = 0
hec_https = 0
host = 192.168.99.2
index = main
index_message_header = 1
index_message_properties = 1
init_mode = jndi
jms_connection_factory_name = connectionFactory
jndi_initialcontext_factory = org.apache.activemq.jndi.ActiveMQInitialContextFactory
jndi_provider_url = tcp://192.168.99.2:61616
output_type = stdout
sourcetype = jms
strip_newlines = 1

4) Rebooted Splunk service.

However, I am getting the following error from the logs.

09-14-2016 00:41:25.009 +0800 ERROR ExecProcessor - message from "python "C:\Program Files\Splunk\etc\apps\jms_ta\bin\jms.py"" Stanza jms://queue/:MyQueue : Error connecting : javax.naming.NameNotFoundException: connectionFactory

Can anyone advise me on what went wrong? Thank you!

I was having the same issue and just wanted to pass along the solution in case anyone comes across it again. The solution was to create a jar file with the jndi.properties file, this allowed the properties to be read. And in the case of ActiveMQ 15.5.0 the property for connectionFactoryNames was added as shown below:
//-----
java.naming.factory.initial = org.apache.activemq.jndi.ActiveMQInitialContextFactory
connectionFactoryNames = connectionFactory, queueConnectionFactory, topicConnectionFactry
java.naming.provider.url = tcp://localhost:61616
queue.MyQueue = EVENTS.Q
//-----

You are not supposed to use a jndi.properties file
You are supposed to properly define your jndi properties in your inputs.conf stanza
At least thats what I do when setting up connections to ActiveMQ successfully

[Damien_Dallimor]

According to your logs this is wrong :

jms_connection_factory_name = connectionFactory

So look in your ActiveMQ config for the correct JNDI name of your connection factory. Perhaps Uppercase ? ConnectionFactory ?

Also , you don't need a jndi.properties file on the classpath.

Hi Damien,

Thanks for your reply.

In my ActiveMQ config, I have a jndi.properties file that states the connection factory name as connectionFactory.

Where can I look in ActiveMQ config for the correct connection factory name?

[Damien_Dallimor]

I'm going to guess there is a management console ?

Docs : http://activemq.apache.org/web-console.html

[michaeltay]

Hi Damien,

Yes there is an ActiveMQ management console, but I could not find any connection factory name to be configured on the management console.

[Damien_Dallimor]

This example code in the ActiveMQ docs uses "ConnectionFactory" , note the casing.

Hi Damien,

I changed inputs.conf to reflect "ConnectionFactory", but now it is giving another error:

Stanza jms://queue/:MyQueue : Error connecting : javax.naming.NameNotFoundException: MyQueue

I do have a queue in ActiveMQ named MyQueue.

[Damien_Dallimor]

Perhaps you are using a dynamicQueue.

So again, as per the docs that I'm just reading back to you here, perhaps the queue jndi name is dynamicQueues/MyQueue :
