It should be part of your jackd installation. Since you seem to be on

RHEL, the package is called j-a-c-k-example-clients or something like

this.

This is ancient.
Linux audio is bleeding edge, RHEL is the exact opposite. You may want

to include the CCRMA repository.
Note that you don't necessarily have to update, you're just using it

wrong atm.

The port= needs further tweaks. That's up to you to figure out what

to put there.
A proper port name looks like "clientname:portname".

See, that's why I recommended to use patchage, where you can simply wire

it up graphically.
Alternatives to patchage: qjackctl, shell
Shell: Once you have your example-clients installed, you can use
   $ jack_lsp
to figure out the exact portnames and
   $ jack_connect mplayer:foo  silentjack:input
or however the ports are called.
I guess you want to add "name=mplayer" to mplayer's jack output module

to prevent it from creating a name that changes every time you restart

mplayer.
Cheers
