JBoss Messaging with JMeter

[pradjboss1]

I am trying load test JBoss Messaging 1.4.3.GA integrated in Jboss 5.1.0.GA with JMeter. I have added JMS Publisher and Subscribers samplers in JMeter with following configuration.

Initial Context Factory : org.jnp.interfaces.NamingContextFactory
Provider URL : jnp://localhost:1099
Connection Factory : ConnectionFactory

Topic : "/topic/test_appln_data"

I am getting following error for Publisher as well as Subscriber :-

I have added following jars in jmeter/lib directory:-

jboss-logging-jdk.jar
jboss-logging-log4j.jar
jboss-logging-spi.jar
jboss-logmanager.jar
jboss-messaging-client.jar
jboss-messaging-int.jar

jnp-client.jar

I am not able to figure out the cause. Is there any documentation available for load testing with JMeter ?

I think you need to check (using jmx console) that the JMS connection factory and the topic are deployed and their JNDI names match your JMeter configuration.

I am already using the deployed jms topic in my application. So it is working fine from the application. I am able to put message and subscribe to the published message from the app. So the issue is related to JMeter interacting with JBoss Messagaing server.

Did you edit the jmeter.properties (or preferrably the user.properties) file and add the jbossall-client.jar file to the user.classpath setting?

Also, exactly what version of JMeter are you using? Line 86 in the Publisher.java I have could not yield an NPE.  By the way, I recommend getting the very latest JMeter when using JMS - there was a significant bug due to some very poorly written initialization code.
