Thanks for the Quartz project, I'll try it. for the moment I've got my own
Thread Management system but using standard is for me a better thing.

I hope that whan I'll stop tomcat Quatrz will shutdown too in a short time.

Thx,

[OT] RE: automatic periodic execution of code

2005-02-16 Thread Barnett, Brian W. 
Are you trying to configure Quartz in web.xml as a servlet or in
struts-config.xml as a struts plug-in?

We're using Tomcat, not WebSphere, but it seems like we ran into a few
issues trying to run it as a servlet. I don't remember what the issues were,
sorry. 

We ended up running it as a struts plug-in. Here's some sample code:

--snippet from struts-config.xml--
plug-in className=com.scholar.plugin.QuartzPlugin/  

--QuartzPlugin class--
public class QuartzPlugin implements PlugIn {
private final static Log log =
LogFactory.getLog(QuartzPlugin.class.getName());
private String SCHOLAR_GROUP = ScholarGroup;
Scheduler sched;

public void init(ActionServlet servlet, ModuleConfig moduleConfig)
  throws ServletException {
log.info(Quartz starting);

try {
sched = StdSchedulerFactory.getDefaultScheduler();
sched.start();

// Register job listeners with the scheduler
sched.addJobListener(new Stethoscope());

// Get the JobDetail object for our HeartBeatJob
JobDetail jobDetail =
sched.getJobDetail(HeartBeatJob, ScholarJobGroup);

// Assign the Stethoscope to listen to the heart
beat.
jobDetail.addJobListener(Stethoscope.LISTENER_NAME);

} catch (Exception e) {
log.info(Quartz Scheduler failed to initialize:  +
e.toString());
throw new ServletException(e);
}

log.debug(Quartz started);
}

public void destroy() {
log.info(Quartz stopping);

try {
sched.shutdown();
} catch (SchedulerException ex) {
ex.printStackTrace();
}

sched = null;
}

Thanks for the answer brian ...I will have a look at your sample
carrefully...

Yes, I'm trying to configure Quartz with Websphere using a Servletbut
I'm not sure of my Quartz.properties file to begin...:( The documentation is
very poor and not much support...maybe I will have to use it another way
(like your plugin suggestion)..

Anyone have managed configure Quartz with Websphere?

TIA

automatic periodic execution of code

Hi,



What would be the recommended way to execute some code periodically on
tomcat/appserver?



Should I

1.  start a thread (not recommended in appserver and tomcat?) and do
it in the run method
2.  use third party tool like Quartz
3.  or is there existing struts plugin to do it?
