Previous code is


Job job = new Job("My Job") {
//run implementation here
};
job.schedule()

changed to


Job job = new Job("My Job") {
//run implementation here
};

IWorkbenchSiteProgressService service = (IWorkbenchSiteProgressService) getSite()
.getAdapter(IWorkbenchSiteProgressService.class);
service.schedule(job);

Then every time you get job running, a busy icon will appear on the view heading tab.
