Jmeter 4.0 error when monitoring 1.6 JVM

[Chetan_5]

Hello,

I am trying to monitor a Tomcat JVM with Jmeter 4.0. Jmeter attaches dynamically to the JVM gives me the following error when I try to monitor it from the console...

Exception in thread "communicator thread" java.lang.NoSuchMethodError: javax.xml.parsers.SAXParser.reset()V
at com.hp.jmeter.jvmagent.jmx.c.a.a(Unknown Source)
at com.hp.jmeter.jvmagent.jmx.JMXManager.invokeCommand(Unknown Source)
The HPjmeter Agent has encountered an error (log file: /var/opt/hpjmeter/log/HPjmeter.jvmagent_8599.log).
Please contact java-tools-support@hp.com
HPjmeter Agent terminated.

The environment is HP-UX 11.23, JDK 1.6.0.04.00. Email to java-tools-support bounces back...

Shalom,

This is a peer to peer forum, not a substitute for Java support from HP. To deal with the email bounce, contact your nearest HP response center.

If you have a software service contract you can contact support.

JVM 1.6 is relatively new, you may need a new version of Jmeter to work with it.

Hi Steven,

I guess I didnt ask the question.. I just wanted to find out if anybody out there ran into this issue Im having.

I have been using ITRC for 10 years now and am aware that its a peer to peer forum ..

THanks,
Chetan

Sorry for the misunderstanding there. The post read like a support request. No offense intended. The response was supposed to illustrate that actual support requests should go elsewhere. I'm sure the email address is misconfigured or the application has an email address in it that was never authorized.

I have run into similar problems in the past. When I first found jmeter and started playing with it, it failed to work with the bleeding edge version of java. Subsequent versions of jmeter did work with that version of java/jvm.

(It would have been helpful if you had shown the details of where it got the error.)
Ah, that's another victim of the site alias massacre. ;-)

I'll send your request on and let them know the alias is broken.

Chetan,

I work on HPjmeter and would like to gather a little more information. Have you tried adding the -agentlib:jmeter option to the command line when starting Tomcat? I am trying to find out if you see a failure only when using the dynamic attach feature of HPjmeter.

I forgot to ask - what version of Tomcat are you using?

[Chetan_5]

Hi Jeff,

I get the same error when using agentlib ...
