Free Native Launcher For Java At Linux and Mac

Question

My Java application require a huge memory heap. I need to launch my application using

java -Xms32m -Xmx128m xyz.jar

Hence, I would like to create native launcher for my Java application, where I can pass the JVM heap size parameters in. I plan to use JSmooth http://jsmooth.sourceforge.net/ for Windows platform.

However, I would also like to create native launcher for Linux and Mac. May I know which open source/ free software can help me to do so?

LaunchAnywhere http://www.zerog.com/iamanual/usermanual_ia55/WebHelp/launchanywhere/abo12e.htm

seem good. But it is a commercial software.

Thanks.

Answer 1

Hm, you might consider using Java Webstart. It's a bit more than just a launcher, but it can do the things you want. It eases deployment, and you can also install applications manually and use them offline, and it's cross-platform.

Or you can just write a simple launcher shell script. Many apps do that, and it works fine.

Answer 2

This may not be the answer you want, but I would use an application bundle on MacOS and a simple shell script on linux/unix.

Only reason really is that the end user experience of using web start and or shell scripts on OSX just isn't that great, Mac users expect everything to work like a Mac app bundle.
