I got this inside my of my batch file but i don't get my server name plus playerlost dunno why but so far as I know this should be the way how it needs to be 

You're missing a ^ at the end of -batchmode, making the .bat file invalid. In .bat files, the ^ indicates that it should read the next line as well for command-line arguments.
