I have all of the Java stuff installed but still cant run .jar applications.
 
Hi guys. I just installed Fedora and removed Ubuntu. Java 7 worked fine on Ubuntu, and I have all of the stuff for Java 7 on Fedora 19 but still can't run things like the new Minecraft Launcher (it is an executable Jar file). Can anyone tell me what I am doing wrong?

WHAT exactly did you install ?
fedora by default DOSE NOT use Oracles JAVA ! it uses OpenJDK
openjdk is what is in the fedora repos and is what is installed using yum ( by default )

now Oracles JAVA 1.7 can be installed BUT you must reset "alternatives"

see Mjmwired's page
http://www.mjmwired.net/resources/mj...-f19.html#java

most things will work with the opensource OpenJDK but not EVERYTHING
somethings will need Oracles JAVA 1.7
or the now dead and unsupported Oracles "JAVA 1.6 "

Fedora , unlike Ubuntu , will NEVER ship with NON free NON gpl's software

no Adobe flash, NO Oracle Java , no mp3, no MS's .wmv , and so on

Hi there,
well the thing for helping you is that you do not mention what you have done ;)
So, for someone to be able to help you will have to tell him/her
what have installed? (just like JohnW says above)
how are you trying to run this .jar file?
were there any error messages when you tried running the .jar file?
