    RHQ and Infinispan monitoring issue

    sniklas Newbie

      Hello,

       

      I did a completely fresh setup of RHQ and Infinispan on our test-systems today and followed the instructions on the various documentation sites to monitor my systems.

       

      For some reason the I was alerted a few minutes after I installed the infinispan module in the agent plugins that the DefaultCacheManager isn't available.

       

      RHQ-Server

      Version: 4.5.1, Build Number: c880f5a, java version "1.7.0_04"

      Standard setup with Oracle and Infinispan RHQ Plugin 5.1.6.FINAL

       

      RHQ-Agent

      Version=RHQ 4.5.1, Build Number: c880f5a, java version "1.7.0_04"

       

      Infinispan

      Version: 5.1.6.FINAL, java version "1.7.0_04"

      2 nodes with minimal configuration: distributed clustering, 1 named cache and jgroups tcp configuration, globalJmxStatistics enabled on global and named cache level

       

      java.lang.ClassCastException: org.rhq.plugins.jmx.JMXServerComponent cannot be cast to org.rhq.plugins.jmx.MBeanResourceComponent

      Any ideas how to fix that?
