SERVERE Forge not launching

[RhinoDaCeros]

I know how to port forward and start a server up but I need an answer to this one

I start up launch.bat and it all works fine then I see an error saying that Forge could not launch that is stopping me from making the server (This is on Java 8 BTW)

I try Java 7 and get this

java -Xmx3G -Xms2G -jar BTeam.jar nogui 'java' is not reconized as an internal or external command
