Ender Portal and The End.

[agentexeider]

when I try to make an Ender portal it doesn't open, and when I use the tp command to teleport there directly it loads me in mid air and drops me to my doom.

 

I have been reading about a ender portal jar file that supposedly fixes it but is it for the latest version of the server?

 

I've been trying to load it but the server doesn't seem to recognize it.

Not unlike the Nether, there is a block dimensional correlation between the Overworld and the End. There will be "land" in the End around where the end portal is located inside of a stronghold. Teleporting directly to DIM1 when far away from that location in the Overworld will yield you empty space and since you didn't use the portal there will be no platform automatically created underneath you to prevent you from falling into the void.
