Please help,problem when creating Jar.

Question

I am somewhat new to Java...But I made a simple program,and then tried to create a Jar file.
Now all my Java commands where in /program files/Java/JavaSDK/Bin,it was a hassle to CD to that everytime I wanted to use a command,so I coppied all the commands in BIn directory,and put them in System 32,I suppose this is ok? That was my first question.
My next one is,when i try creating a Jar file..I suppose I am doing ti right,but the entire command prompt fills up with code,the ASCII and all the symbols....and a REALLY loud constant beep comes from my computer,and speakers..and it seems it doesnt create anything by this code in the screen and th noise..
Please help.

My next one is,when i try creating a Jar file..I
suppose I am doing ti right,but the entire command
prompt fills up with code,the ASCII and all the
symbols....and a REALLY loud constant beep comes from
my computer,and speakers..and it seems it doesnt
create anything by this code in the screen and th
noise..It is from jar help:
Example 1: to archive two class files into an archive called classes.jar:
jar cvf classes.jar Foo.class Bar.class
Example 2: use an existing manifest file 'mymanifest' and archive all the
files in the foo/ directory into 'classes.jar':
jar cvfm classes.jar mymanifest -C foo/ .
