how to read jar file

Mon Dec 11 17:24:00 GMT 2000

>From the document on the Red Hat web site, the gcj
program can read a jar file. But I tried the gcj
which come from Red Hat 7 and did not make it work. 
It seems to me that gcj can only read .java or .class
files. Can anyone help me with this and tell me exact
command format? Thanks,
Ian Zhang
