    jboss scheduler

    v ck Newbie

      chaps,

      am using jboss scheduler to schedule an mbean.
      the method am trying to schedule uses another mbean method(@depends)
      but when this method is sceduled, the second mbean method throws a null pointer.

      here s the scenario

      @LocalBinding(jndiBinding = "xx/yy/local")
      @RemoteBinding(jndiBinding = "xx/yy/remote")
      @Service(objectName = "xx:service=yy")
      @Management(...)
      @Depends( { "aa:service=Environment" })
      public class MyClass implements Schedulable {

      @Depends("a:service=Environment")
      private Environment e;

      public mySchedulableMethod() {
      //calls method on Environment
      e.something(); //this throws null pointer
      }

      }


      any ideas??

          sorry , My bad!
          my xml configuration in jboss-service.xml was incorrect.


          false
          xx:service=yy
          mySchedulableMethod()
          MM/dd/yyyy kk:mm:ss
          08/01/2007 23:59:00
          10000
          1




          I had used attribute "SchedulableClass" instead of SchedulableBean.

          silly me!
