I'd like just to share my piece of code, maybe it will be useful for somebody. It is based on the comment from jiggawagga, but it can terminate many processes:

@ECHO off
SETLOCAL ENABLEDELAYEDEXPANSION

REM kill old server process
SET pIdNotToKill=
SET pIdFilter=

FOR /F "tokens=2" %%I IN (%SERVER_HOME%\psid.txt) DO (
    IF NOT "%%I"=="No" (
        SET pIdNotToKill=!pIdNotToKill! %%I
        SET pIdFilter=!pIdFilter! /FI "PID ne %%I"
    )
)

IF NOT "!pIdNotToKill!"=="" (
    ECHO Killing all Java processes except%pIdNotToKill%
    ECHO TASKKILL command will be called with the filter%pIdFilter%
    TASKKILL /F /IM java.exe %pIdFilter%
)

DEL %SERVER_HOME%\psid.txt

TASKLIST /NH /FI "IMAGENAME eq java.exe" > %SERVER_HOME%\psid.txt

right before I start server process.
