Blank Minecraft Server File

I have downloaded the java model instead of simply the exe. file as I've seen others with the same drawback try to repair the difficulty this way. Minecraft servers I'm certain that the exports and imports for the IP handle connections and have entered the 25565, and listed both TCP and UDP or no matter. I use the CT-5374 which is a Comtrend router. But the Minecraft server file; the stats, log and chat, and gamers all present up blank. Nonetheless it does not list it as a "java" or ".jar" or whatever after the file identify. I am undecided what the difficulty is aside from it is having to deal with the blankness however I am uninterested in operating into all of those issues. I've been troubleshooting for practically three straight hours and still can not appear to quite fix it. I can be part of onto my multiplayer server, however my mates can not, and I'm unsure of what to do now.
