After putting the following into terminal,
xdg-mime default .local/share/applications/update-sun-jre-java.desktop application/java-archive
Nothing has changed.

But that's okay, it's not a big deal, if I don't find a way to change the default to open with Java Runtime, no problem.

When I double-click the file or use xdg-open file-in-question.jar or right-click > open with java web start: java 7 in some form starts up and then reports "Unable to launch application". However when I right click on the .jar file, click open with > java runtime, then in opens fine.

I don't want to mark it as solved, because my original question isn't solved. Is it important to close this thread? I thought that since I have a common distro and that my questions could help others, I would ask for help. Thanks again for your patience!

Actually, you can't mark it as SOLVED because it's not your thread. But never mind, hopefully if we find a solution, then it will benefit the OP too.


When you go Properties > Open With... is there an option to "Browse for more" or "Browse for executable" or something similar? It may only appear when you click on "Show Other Applications". If so, then just find java and select it. If not, then could we maybe have a screenshot? I feel there must be a way of doing what you want to do...

There is an option "show other applications" but can't browse, it only gives a list of more programs, and Java Runtime isn't on the list. Java WebStart will not open the .jar file and reports "Unable to launch application". Whereas [right-click on file > open with Java Runtime] runs .jar file perfectly.

Hm... And that "Add" button is greyed out no matter where/what you click? Perhaps we need to find someone who actually runs Mint, or maybe I can boot it in a VM...

The add button only becomes available after selecting another one in the list other than the current default. No option to browse for program.

This is not urgent or really important. Why don't we just wait and see if somebody that's running Mint sees this thread? If not, no big deal...

The thread's title indicates Ubuntu 12.04 so it may not grab a Mint user's attention. Have you tried posting this in the Mint forums?

Okay, we got the problem sorted at least in cpocanada's case: the problem was that the correct mimetype is "application/x-java-archive" (I mistakenly said "application/java-archive"). So the fix was to use the following line in .local/share/applications/mimeapps.list:

@0wn3r: If this also fixes your problem, then please mark this thread as SOLVED using the link at the top of the page.
