    NullPointer refererncing Stateful Session Bean in Quartz Job

      I must be missing something here... but I've been staring at this stacktrace for hours:


      A snippet from my Quartz job looks like this and it runs as scheduled:


      @Name("processor")
@AutoCreate
@Scope(ScopeType.APPLICATION)
public class ScheduleProcessor { 
     @In(required=false, create=true)
     AuthManagerSearchService amSearch;
.
.
.
     private void addPersonFromBulk(Person person) {
          String uid = person.getUid();
          try {
            logadd.debug("Bulk Add Person: " + uid);
            if (! amSearch.uidIsUnique(uid)) <--- throws NullPointer
{
.
.
.
}


      amSearch looks like this. It works fine from the web app...


      @Stateful
@Name("amSearch")
@Scope(ScopeType.APPLICATION)
@AutoCreate
public class AuthManagerSearchFacade implements AuthManagerSearchService {

     public AuthManagerSearchFacade(){};

     @Create
     public void init(){
     }
.
.
.
}


      Here is the stacktrace:

      Why can't SEAM successfully inject the amSearch component? I must be missing something simple...


      Thanks in advance.
