There are several very useful applets from Mint Cinnamon which I would like to be able to use on another distribution: http://cinnamon-spices.linuxmint.com/applets.

I know how to write a shell script containing a command to change to the appropriate directory, then start a Java program, for example:
I think these applets are written in Javascript, is it possible to write a similar shell script for this type of program?

When I have created the shell script, I assume I could create a .desktop file to run it, is that correct?

Ubuntu specific: Would it then be possible to get it onto the Ubuntu Launcher?

If you are creating a launcher and put these commands there (type should be Application in terminal)
What is the error here so you are not able to execute this in a launcher?

eklavya:

I listed that code fragment to illustrate that I know how to run a Java program. The Cinnamon progams are Javascript which I believe to be an entirely different language. I do not know how to run those.

Query no longer relevant as I am now using Ubuntu MATE.
