g.sh(cmd1);
String cmd2 = "/sbin/chkconfig --add tomcat";
g.sh(cmd2);
String[] cmd = new String[] {"/sbin/chkconfig", "--list"};

but i can execute the command in system, could show me the reason, Thanks!
Well it's something to do with the guest being either a much older or
much newer version of Linux than the host, or perhaps it's a different
architecture (32 vs 64 bits?), or not even Linux at all.
The way to solve this is to use a firstboot script:

However to run the command it may be better to run the command using
a
"firstboot" script. See:
http://libguestfs.org/guestfs.3.html#running-commands
http://libguestfs.org/virt-sysprep.1.html#firstboot-
(Note that the ability to use firstboot scripts was only added very
recently to virt-sysprep).
