How do I setup Unity to right-click-open a java file? I have tried to "set the default action" but the action is not listed and I cannot add an action from the menus. When I right-click-properties then click the "open with" tab, the "add" button is greyed out.
I write alot of java software. I need the ability to open it from the Desktop.
Open /usr/share/applications and look for a file named "OpenJDK Java 6 Runtime". If it doesn't exists create a file named /usr/share/applications/openjdk-6-java.desktop with the following contents:
[Desktop Entry]
Name=OpenJDK Java 6 Runtime
Comment=OpenJDK Java 6 Runtime
Exec=cautious-launcher %f /usr/lib/jvm/java-6-openjdk-i386/bin/java -jar
Terminal=false
Type=Application
Icon=openjdk-6
MimeType=application/x-java-archive;application/java-archive;application/x-jar;
NoDisplay=true
You should change the "/usr/lib/jvm/java-6-openjdk-i386/bin/java" part of Exec to the location of java on your system. Then reboot and the option should be there.
14.04 LTS user here. Got OpenJDK working from desktop with:
