Finding javac.exe with Win32 command line NO ENV VARIABLES

[KD007]

Hi. I have a compiler script (.bat) that I wrote for java. Using java.exe is really easy, since java always places a dummy copy of java.exe in %windir%\system32. This means that I can always type "java.exe" no matter what my paths and %cd% are. Is there a way to automatically use javac.exe in a similar fashion, without setting %path% or %java_home%. Currently my batch script has this in it, and it's getting messy:

SET JDKVER=0.0.0_00
if EXIST "%PFPATH%\jdk1.7.0_00" SET JDKVER=1.7.0_00
if EXIST "%PFPATH%\jdk1.7.0_01" SET JDKVER=1.7.0_01
if EXIST "%PFPATH%\jdk1.7.0_02" SET JDKVER=1.7.0_02
if EXIST "%PFPATH%\jdk1.7.0_03" SET JDKVER=1.7.0_03
if EXIST "%PFPATH%\jdk1.7.0_04" SET JDKVER=1.7.0_04
if EXIST "%PFPATH%\jdk1.7.0_05" SET JDKVER=1.7.0_05
if EXIST "%PFPATH%\jdk1.7.0_06" SET JDKVER=1.7.0_06
if EXIST "%PFPATH%\jdk1.7.0_07" SET JDKVER=1.7.0_07
if EXIST "%PFPATH%\jdk1.7.0_08" SET JDKVER=1.7.0_08
if EXIST "%PFPATH%\jdk1.7.0_09" SET JDKVER=1.7.0_09
if EXIST "%PFPATH%\jdk1.7.0_10" SET JDKVER=1.7.0_10
if EXIST "%PFPATH%\jdk1.7.0_11" SET JDKVER=1.7.0_11
if EXIST "%PFPATH%\jdk1.7.0_12" SET JDKVER=1.7.0_12
if EXIST "%PFPATH%\jdk1.7.0_13" SET JDKVER=1.7.0_13
if EXIST "%PFPATH%\jdk1.7.0_14" SET JDKVER=1.7.0_14
if EXIST "%PFPATH%\jdk1.7.0_15" SET JDKVER=1.7.0_15
if EXIST "%PFPATH%\jdk1.7.0_16" SET JDKVER=1.7.0_16
if EXIST "%PFPATH%\jdk1.7.0_17" SET JDKVER=1.7.0_17

I guess what I'm looking for is some sort of copy of javac.exe that does the same thing as the dummy java.exe. Just finds the real javac.exe and passes on the params to it.
