Hi,

my application needs to kick off event at regular intervals ( say daily or
weekly ).. is there any way to
do this?

The EPP project's Usage Data Collector
(http://www.eclipse.org/epp/usagedata/) does something like that; it
periodically uploads usage data on a user-configured schedule.
There are links to view or get the source code on that web page, and the
newsgroup to ask questions about it is eclipse.technology.packaging
(where EPP questions, in general, belong).

If that does not provide any help, I'd take a look at the Quartz
framework: http://www.opensymphony.com/quartz/ - I've used that several
times, though not in an Eclipse plugin or RCP app.

Hope this helps,
Eric

With a few lines of code you can do it yourself...

Use a preference value to store the last kick off..

Use a ScheduledExecutorService on start of your Application to schedule
the next kick off...

Or better, use the Jobs API. It allows to schedule a job to start in the
future.

So does the ScheduledExecutorService.
I have found Jobs to be nice if you need to show progress in the GUI
(and cancelling). Or if you depend on resources to be locked.

Though for simple stuff Jobs api is often Overkill and creating a
ScheduledExecutorService for the app will be easier.

Might be a matter of preference. Usually when I need some functionality
and the stdlib provides an equally good solution I would choose the java
stdlib over other api.

Walter,

The Timer and TimerTask classes in java.util are also quite interesting.

Cheers
