Re: [OT] RE: automatic periodic execution of code
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

[OT] RE: automatic periodic execution of code
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--
--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;
}

Hello,
I know it is not the right place but does someone make Quartz works with
Websphere???
I'm trying this since two days and I'm unable to make it worksand I
haven't find a Quartz mailing list...
If somebody has experience and can help me...TIA...
