So the answer is: /dev/sda5 doesn't hosts a jfs filesystem.
Maybe you used a wrong minor number (5) or event a wrong
major letter (a).

To me it is useless to give -t to mount Linux filesystems,
it can handle it automatically (verified for vfat, etx2/3/4,
xfs, etc.).  This may be required for loop, ntfs, etc. mounts
only.

Moreover, any running livecd distro should also have a (custom)
sudoers file, so just copy and edit (simplify) it to your host
/etc/sudoers.
