Path to Java\jdk1.6.0_02\bin goes away

I keep all of my java files in one directory.

I use the following batch file to make jar files.

When I change the path either with this batch file or

manually on the command line, the path reverts to the

old path for any other command-line window.

REM 1st arg is prog name,

REM 2nd arg is dummy x (or p to augmentfor javac,jar,java.exe)

if %2==p set PATH=%PATH%;C:\"Program Files"\Java\jdk1.6.0_02\bin

path

dir %1*.*

erase *.class

erase %1.jar

dir %1*.*

javac %1.java

jar cvfe %1.jar %1 *.class

dir %1*.*

erase *.class

dir %1*.*

java -jar %1.jar

REM the previous (last) command checks that the program

REM runs without parameters, usually giving instructions

How do I make a more lasting change to the path?

I use Windows Vista.
