Java app autostart

Hello,

I am very new to Mac OS X. But I have developed an executable Java (jar) app that launches fine from Terminal using 'open' or 'java -jar' command, or when double-clicked in desktop.

However, I need to make this jar app start at login time. I looked at StartupItems directory but it didn't work. I am even sure if this is the right location for making jar files to launch.

Could somebody please give me a hint on what directory I should use so this jar file would launch automatically at login?

P.S. It is important for me to know the absolute path where I can place this jar for autolaunch (not from the GUI features) because I'll later be doing File I/O in there.

Thank you so much,
Victor.

In the windows world you would write a batch file to issue the java -jar command so im guessing that in osx there is a similar shell? script you need to write.

Thank you!
