First be sure you have installed JDK , but not the JRE (jre comes without the javac).

Here's how you can the JAVA_HOME\bin to your path (in case you have installed JDK):

for /f  "delims=" %j in ('reg query "HKEY_LOCAL_MACHINE\SOFTWARE\JavaSoft\Java Development Kit\1.6" /v JavaHome') do @set jreg=%j
set jreg=%jreg:    JavaHome    REG_SZ    =%
setx PATH "%jreg%\bin";%PATH%
