If you want to have a .cmd file to run your jar, then such a file could look like this

@ECHO OFF
SET JRE_HOME=

Also using the this option require your mainifest to have the attibute Main-Class which tells which class to run / is the entry point for your program.

Better yet include myfile.jar in the classpath an pass your main class to java.exe

@ECHO OFF
SET JRE_HOME=
SET MY_CLASSPATH=;myfile.jar
%JRE_HOME%\bin\java.exe -cp %MY_CLASSPATH%
