[jira] [Commented] (AMQ-4247) Jolokia error in latest 5.8 snapshot

    [ https://issues.apache.org/jira/browse/AMQ-4247?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13546725#comment-13546725 ]

------------------------------------

Hi Lionel,

I can reproduce this. What are you trying to access at j4p? There's a brief explanation how to access ActiveMQ MBean information using Jolokia here

http://activemq.apache.org/rest.html#REST-RestManagement

For more info on url syntax, take a look at Jolokia manual.

> Using the latest ActiveMQ 5.8 snapshot, I'm getting errors when trying to access /j4p:
> HTTP ERROR 503
> Problem accessing /j4p/. Reason:
>     java.lang.IllegalStateException: Cannot load extractor org.jolokia.converter.json.simplifier.ClassSimplifier defined in jar:file:/usr/activemq/lib/web/jolokia-core-1.0.6.jar!/META-INF/simplifiers-default : java.lang.ClassCastException: org.jolokia.converter.json.simplifier.ClassSimplifier cannot be cast to org.jmx4perl.converter.json.Extractor. Aborting
> Is this a known problem? Is there any documentation on how to use and/or configure Jolokia with ActiveMQ?
