Do you want to implement a cron job for a JAR file? With high probability you will not even care about this, but since it is really something easy I would like to share this information with you!

You do not have to do something incredible, just use the Windows Task Scheduler. You will realise that Windows Task Scheduler is able to schedule the execution of (executable in Windows) files at any time and with many (interesting) preferences (it is a nice but somewhat hidden application of Windows).

Since a JAR file is not a Windows executable file, all you need to do is:

• Open Windows Task Scheduler (in Vista it is located under system32 folder OR you may find it in Start >> Accessories >> System Tools.
• Create a New Task.
• After editing your scheduling parameters (Triggers), go to Actions and choose Start a Program Action.
• Set script to

  C:\Program Files\Java\jdk1.6.0_02\bin\java.exe

  or wherever your java.exe file is located in.
• Set add arguments option to something like

  -jar C:\Users\YourUsername\PathToJARFile\JARfile.jar

  .

  You are ready to go!
