setting system envarioment variables in java

[garfild Baram]

guys,
How do I set Enviroment variables(JAVA_HOME,MYSQL_HOME...) and different addresses in the system Path using java code?
Thanks

What are you trying to do?

A process can only change the copies of the environment variables of itself and set the environment of child processes it might spawn, so setting them is fairly useless.

hey,
All I'm trying to do is to set through the code different settings for JAVA_HOME and PATH.
I have an installation kit and each compter has different settings.
Now I use a setEnv.cmd file:
System\Service\setx JAVA_HOME c:\j2sdk1.4.2_02 -m
set JAVA_HOME=c:\j2sdk1.4.2_02
System\Service\setx MYSQL_HOME c:\mysql -m
set MYSQL_HOME=c:\mysql
System\Service\setx path "c:\j2sdk1.4.2_02\bin;c:\Eldat Common Path;c:\perl\bin;%path%" -m
set path=c:\j2sdk1.4.2_02\bin;c:\Eldat Common Path;c:\perl\bin;%path%;


The problem here is the static addresses, If I set it in the code it can be dynamic.

Can I do it?

thanks

I don't really undestand the problem --- why don't you just make the part with for example "c:\j2sdk1.4.2_02" configurable instead of hardcoding it?
