Attached is an image of the command Prompt window displaying the start up info and the 7 help pages.
This is the command I use for the .BAT file –
java -jar -Xmx1024M -Xms1024M minecraft_server.1.7.5.jar nogui
Obviously you can sum up the 1024M by using 1G or if you are giving it more 2G, 3G etc…
Make sure the server Jar file matches the actual JAR Version you are attempting to launch
nogui – This will make it so that the Java SUN console does not launch and run in tandem with the CMD prompt!
