[embjopr-issues] [JBoss JIRA] Commented: (EMBJOPR-280) jboss-as-5 plugin: JTA Metrics not found during discovery scan

[Ian Springer (JIRA)]

    [ https://jira.jboss.org/browse/EMBJOPR-280?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12535672#action_12535672 ] 

Ian Springer commented on EMBJOPR-280:
--------------------------------------

So, the as5 plugin expects there to be a single managed component of type MCBean:JTA (i.e. a "singleton" managed component), which was always the case in my testing with AS and EAP 5.x. It appears in AS6, there can potentially be more than one MCBean:JTA component deployed (the log you attached shows there were two). I'll need to figure out why there are more than two and which one we want to use to retrieve the tx metrics and then update the as5 plugin code so that it is compatible with both 5.x and 6.x.
