Does anyone have any suggestions for an open source scheduler maybe written or Java that will allow for scheduling batch jobs and also has the capability to watch for events to kick off jobs?

The built in scheduler will not suffice.

Thanks,

All those seem to be Inly able to schedule java applications. Correct me if I'm wrong...

I need to be able to schedule .exe and .bat jobs do any if those offer that?

Something like zcron looks promising but since I was hoping to run this on my desktop at work it's a bust...

But you can wrap  .exe and .bat in Java Runtime.getUntiame().exec(...)

Quartz also has NativeJob facility to run native job, like .exe

Maybe z-cron is more suitable if you are not focused so much on java

Maybe I'm overlooking Quartz...

Do you have an example of how I would execute a .bat in Quartz?

I saw such question about executing .exe file:
http://stackoverflow.com/questions/2806612/quartz-scheduler-not-running-the-task

JobDataMap map = new JobDataMap();
map.put(NativeJob.PROP_COMMAND, "c:/WINDOWS/notepad.exe");

In this question the author could not see notapd starting, but ther is a provision.

But there is not much doubt once you can execute any java method, say like here
http://www.roseindia.net/quartz/quartz-scheduler-tutorial.shtml
 so you can use Runtime.getRuntime().exec(...)
and start exe file and batch file in this way from within java code.


There is also Quartz.NET which should definitely start not only java jobs:
http://quartznet.sourceforge.net/faq.html

though it seems to me that z-cron looks more popular than Quartz.NET

But if most of your jobs will not be based on java - I'd rather suggest to use non-java
scheduler.

Since this is a Windows 7 machine I don't really see a lot of options.

Quartz and Quarts.net look promising as well as Zcron.

Thanks for all the help and suggestions.
