I could do it with OpenJDK, but it didn't work for my purposes so I'm using Oracle's JRE 7. I can run the jar through the terminal with
java -jar filename.jar
and can also right click the file and click Open With > Oracle Java 7 Runtime, but I can't set the Java 7 Runtime by default in the Properties menu (probably because the runtime executable isn't located in /usr/bin
).
Any quick command lines I can type to set it so I can just hit enter on the file and launch the .jar with Java 7?
