Help plz?

I wiped my hard drive yesterday for a fresh start, and after reinstalling java and playing a bit of AotBT ssp, I tried to download and start a smp server. When launching the server batch fle, instead of doing what it normally does, it says: "Java" not recognized as an internal or external command, operable program or batch file. c:/users/(my user)/desktop/AotBT Server>pause Press any key to continue When i press any key, the program closes. I have java and have been playing minecraft. What is wrong? Thanks!

Me and three friends made a hamachi server last night for Attack of the B-Team, and everything worked just fine. This morning when I rebooted the server, I (the host and owner) could connect and play just fine, but everyone else when joining would see the world like normally for a few seconds, then the screen would go "black" and show the screen that you get when you have gravel fall on you. As this happened, they would sink through the ground until they came out through bedrock and into the void, where they would continue to sink until they logged out. On my screen, they were just standing still, and I could hit them once and it would hurt them on my screen, but they would be ok still. Any further attempts to damage them would not work on my screen either. After them relogging and me hitting them once a few more times, they died. After that, the cool grave thing with all of their items appeared on the ground, and they were met with a respawn screen. When they click respawn, nothing happens. This happens to everyone but me. It worked fine last night, but today we logged on and had to download a few more things from the launch to play (assumably a patch) and I believe that this has broken it. We have tried resetting the server, our computers , everything. Does anyone know how to fix this?
