How come i am unable to open .jar files?

Every time i would try to open a .jar file, it would always pop up a message that says "The Java JAR file "name of file" could not be launched. Check the Console for possible error messages.". i already tried the java launcher and setting it to default even though it already was. And when it says check the console, i don't know what to look for. Please help!

iMac, OS X 10.11
