Jar question

I have a program that runs inside eclipse and works perfectly, handling all exceptions

I made a jar using: jar cvfm classes.jar manifest.mf.txt Coder.class

Coder is the only class I use and it is properly done in the manifest

what can I do to make this jar runnable from windows, like an executable jar kinda thing

I've looked at a bunch of websites so don't point me to one unless it's really realy good

JAR is there on my tools / folder options / file types thing but it still wont run when i double click the jar
