Service not injecting properly into quartz job class With quartz scheduler plugin (v1.0.1) for grails 2.3.6

Question

I've implemented my own quartz job classes that take in a service method . However, the service doesn't seem to be injecting properly into my job class as i always get a nullpointer exception when accessing a service.

How do i get the services to be injected during the trigger of the job .

Any suggestion on how to invoke the method in the service from the Job class

Update 1 : Added the job code and log messages

import org.quartz.Job;
import org.quartz.JobExecutionContext;
import org.quartz.JobExecutionException;
import org.quartz.JobDataMap;

import com.unitrac.app.reportcentre.report.ReportService;

// Logging
import org.apache.commons.logging.LogFactory;


class ReportJob  implements Job {
    
    
    def reportService;               
    def grailsApplication;
    
    
    // Logging
    private static final log = LogFactory.getLog(this);
           

    void execute(JobExecutionContext context) throws JobExecutionException {
        // execute job
      
      
      JobDataMap jobMapData = context.getMergedJobDataMap();          
          
        
      try
        { 
          log.debug("In Report Job  - executing its JOB at "
              + new Date() + " by " + context.getTrigger().getName());
        
         
        
        String groupName =  context.getTrigger().getJobKey().getName();             
        
        log.debug("group Name  : "  + groupName);
               
        reportService.invokeMethod();
          
        }
      
      catch( Exception e )
      {
          log.error("Exception: $e");
      }     
        
    }
}

Answer 1

For what it's worth. I tried all the suggestions above, and it' didn't work for me. I eventually settled for Injecting the service manually from the Grails ApplicationContext.

def ss = Holders.grailsApplication.mainContext.getBean(SampleService.class)

This is better than creating a service using new()

Answer 2

Make sure your job class in in grails-app/jobs and try removing implements Job.
