Environmental Variable help in Vista

I don't use Vista, and I don't know what you mean by "doesn't work," but one thing is certain: Don't put C:\j2sdk1.4.2_14\bin on your classpath. No classes should go there.

Also don't put anything in a jre's ext directory on your classpath. Any classes there will automatically be picked up.

Whenever I try to compile with JCreator I get the message Invalid path, \bin\javac.exe -classpath "C:\Users\William McKeever\Documents\Created Programs\Java Programs" -d "C:\Users\William McKeever\Documents\Created Programs\Java Programs" "C:\Users\William McKeever\Documents\Created Programs\Java Programs\Abracadabra.java"

and javac command is not recognized and -cp gives me a list of commands.

thanks for the info about JRE it was put their automatically I did not enter that variable. also if I do not put it in classpath then where do I put the variable thanks.
