setting default app for .jar files
My primary concern here is setting the default application for handling .jar files to OpenJDK.
I use Linux Mint Debian Edition with LXDE.
When I tried to open a .jar file, it was linked to Eclipse (Java IDE) as the default application. I want to change that to OpenJDK, but it's nowhere to be found in the menus. It's definitely installed though, I checked in Synaptic (and otherwise the .jar file wouldn't be able to run in eclipse either, right?).
How can I make OpenJDK available in the menu?
Since the standard way of doing this is unavailable, is there a CL tool for assigning default applications to file extensions? What command would I have to use for this specific binding (bcs I'm not very good at making the glyphs in your standard man page into a functioning command, I always get it wrong...)?
