Play Framework – Input line is too long…

I have recently come across this problem where Play framework service wouldn’t run on some windows servers and result in the following error:

Input line is too long

The problem is APP_CLASS. Just update it to the following it should work fine:

set "APP_CLASSPATH=%APP_LIB_DIR%\..\conf\;%APP_LIB_DIR%\*"

Note: This would load all the libraries from the APP_LIB_DIR generally set in the same batch file.
