How do I reenable opening jar files by double clicking on them?

How can I make "double click to run" the default behaviour of a jar-file on Nautilus? There is no "Open with OpenJDK Java 7 Runtime" on the "Open with" tab under Properties.

Solution 1:

You can try the following:

If you have OpenJDK Java 7 Runtime installed in your system, then you should have a file named openjdk-7-java.desktop in the folder /usr/share/applications/

Check if you have the .desktop file.

1. Go to the terminal and type:

   cd /usr/share/applications

   ls -l openjdk-7-java.desktop

2. If the result is:

   -rw-r--r-- 1 root root 367 Oct 24 22:29 openjdk-7-java.desktop

3. Then (to associate OpenJDK Java 7 Runtime to the java files) you can edit the file defaults.list also in the folder /usr/share/applications/ .

4. In the terminal type:

   sudo gedit /usr/share/applications/defaults.list

5. Search for application/x-jar and application/x-java-archive in the defualts.list, and change the .desktop file to the openjdk-7-java.desktop and save the changes.

Now the java files should be open with Open JDK 7 by default. To double-click and run, make sure the file has execute permissions.

You can set the permissions in the terminal with: chmod 755 file.jar or right click in the file, permissions tab and click in "Allow executing file as a program"

Finally double-click in the file to run it.

Hope this will helpful!

Regards.
