Can´t run an jnlp file. Shows message "Cannot run application"

so i'm recently starting to work with Java Web Start, everything was ok untill i tried to run my .jnlp file and it showed the message "Cannot run application" giving me only two options "Ok" & "Details". I selected details and this is what it showed:
