How to run an executable file through JRE by default?

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?

I've had a similar question, and I found the answer, it was a missing .desktop file for me, and I included a guide to manually creating one (although I'm hoping that somebody will show me a better way) anyway, here is how I did it.

1) Open Gedit from the Terminal with root privileges usind gksu gedit

2) Open a .desktop file from /usr/share/applications and copy it into a new file.

3) Edit the name, comments, and image to your liking.

4) Change the command to java -jar %u DO NOT FORGET THE %u

5) Save

6) Right click .jar file in nautilus, select properties>open with>show all applications, and select the new entry, select either add or set as default.
