Problem summary

  • ****************************************************************
    * USERS AFFECTED:  IBM WebSphere Application Server V8.5       *
    *                  Liberty profile users working with JMX      *
    *                  MBeans                                      *
    ****************************************************************
    * PROBLEM DESCRIPTION: Liberty profile MBeans do not provide   *
    *                      management interfaces as public APIs    *
    ****************************************************************
    * RECOMMENDATION:                                              *
    ****************************************************************
    MBeans provided by the Liberty profile can be accessed by
    remote clients and applications via an MBeanServerConnection
    instance, but the management interfaces are not exposed as
    public APIs, nor are the interfaces documented. This means
    that a user can work the MBeans via an MBeanServerConnection
    but cannot create a proxy object which allows for cleaner,
    simpler code.  The affected MBeans are those identified by the
    following ObjectNames or ObjectName patterns:
    WebSphere:name=com.ibm.ws.jmx.mbeans.generatePluginConfig
    WebSphere:service=com.ibm.ws.kernel.filemonitor.FileNotification
    MBean
    WebSphere:service=com.ibm.websphere.application.ApplicationMBean
    ,name=*
    WebSphere:type=JvmStats
    WebSphere:type=ServletStats,name=*
    WebSphere:type=ThreadPoolStats,name=Default Executor
    

Problem conclusion

  • Management interfaces have been exported as public API,
    complete with Javadoc, and are available from the jars in
    wlp/dev/ibm-api. All MBeans provided by the Liberty profile
    are now documented in the Information Center and each lists the
    name of the management interface. These interfaces can be used
    to obtain a proxy object and they are exposed via the
    application classloader when the related feature is enabled,
    so they are available for external JMX clients and
    applications alike. The interfaces exported, in the same order
    as the MBeans listed above, are:
    
    com.ibm.websphere.webcontainer.GeneratePluginConfigMBean
    com.ibm.websphere.filemonitor.FileNotificationMBean
    com.ibm.websphere.application.ApplicationMBean
    com.ibm.websphere.monitor.jmx.JvmMXBean
    com.ibm.websphere.webcontainer.ServletStatsMXBean
    com.ibm.websphere.monitor.jmx.ThreadPoolMBean
    
    The fix for this APAR is currently targeted for inclusion in
    fix pack 8.5.0.1. Please refer to the Recommended Updates page
