Please help me create a jar file

[tdashroy]

Okay, this is probably a very newbie question, but i have been looking online on how to make a jar file and everything i come across says that i use the command

jar cf name.jar name.class

yet, whenever i do this in my command prompt it brings up "'jar' is not recognized as an internal or external command, operable program or batch file." Please i really would like to learn how to do this and i have been trying for a while now. Do i need to type java at the beginning or something? I really am completely lost here.

If JAVA_HOME is the directory where your jdk is stored
(similar to C:\Program Files\Java\jdk1.6.0_02\) then your 'jar' tool is stored in
JAVA_HOME\bin. That directory should be part of your PATH variable.
I bet 'javac' doesn't work either now because both jar.exe and javac.exe are
stored in the same directory.

kind regards,
