    WildFly 10 MBean Attribute Persistence

    Mike Burger Newbie

      hi,

      i'm trying to get a service MBean, which is working under JBoss 5, to work under WildFly 10.0.0.Final.

      the deployment works (using the jboss-service.xml at the end of this post),

      changing attributes via JConsole and hawtio jmx-console works,

      but the MBean's attributes are not getting persisted - when redeploying or restarting WildFly the values are getting reset.

       

      under JBoss 5 the attributes get stored in an xml file - how to get this functionality under WildFly?

       

      since i'm very new to this a "how to port for dummies" would be great.

       

      thanks,

      mike

       

      public interface UpdaterMBean
      {
          public String getUpdateURL();
          public void setUpdateURL( String url );
      }
      

       

      public class Updater implements UpdaterMBean
      {
          protected String updateURL;
      
          /**
           * @jmx:managed-attribute
           */    
          @Override
          public String getUpdateURL()
          {
              return updateURL;
          }
