It is not letting me mint at all
my nxt properties config is
#### MINT ####
# Address of the NXT server to which the mint worker submits its transactions (default: localhost).
nxt.mint.serverAddress=localhost
# Use Https when connecting to the server. Note that mint worker accepts any SSL certificate as
# valid, without checking hostname or certificate authority, therefore this will not protect
# you against a man-in-the-middle attack when submitting mint transactions.
nxt.mint.useHttps=false
# Specify a mintable currency code.
nxt.mint.currencyCode=ELEMS
# Secret phrase for the minting account, this secret phrase is sent to the host specified by
# nxt.mint.serverAddress therefore do not specify secret phrase of an account with lots of funds.
nxt.mint.secretPhrase=mysecretphrase
# Number of units to mint per transaction
# The minting difficulty grows linearly with the number of units per mint.
nxt.mint.unitsPerMint=1
# The initial nonce used for minting
# Set to 0 to start with a random nonce.
nxt.mint.initialNonce=0
# Number of concurrency threads used for minting
# Set to 0 allocate one thread per processor core.
nxt.mint.threadPoolSize=1
# When set to false mint transactions are not submitted when a hash is solved.
# Set this value to true to perform actual minting.
nxt.mint.isSubmitted=true
when i try to open mint.bat i get
'java.exe' is not recognized as an internal or external command,
operable program or batch file.
