Here's a very basic way using Expect that should hopefully set you on the path to what you want to accomplish:

Code:
#!/usr/bin/expect -f
#
#

# set credentials - NOT RECOMMENDED METHOD
set u "username"
set p "password"

# get host name from command-line
set h [lindex $argv 0]

# set the command to run
set cmd "date"

# spawn a connection to the host and
# run the given command
spawn ssh -t $u@$h $cmd

# handle the password prompt
expect "?assword:*"
send -- "$p\r"
send -- "\r"

# done
expect eof

I've found reading files using Expect to be a bit flaky, so you could use a while loop to parse your file with the hostnames and feed it to the Expect script like so:

while read hosts;do sendCmd $hosts;done < server_list

Output:

spawn ssh -t username@server1 date
username's Password:
Mon Nov 11 08:52:42 EST 2013
Connection to server1 closed.

asadmin-stop-instance(1AS)					   User Commands					asadmin-stop-instance(1AS)

NAME

       asadmin-stop-instance, stop-instance - stops the specified server instance and all the services associated with it

SYNOPSIS

       stop-instance  [--user  admin_user]  [--password  admin_password]  [--host local_host] [--port 4848] [--local=false] [--domain domain_name]
       [--secure|-s]instance_name

       Use the stop-instance to stop the instance with the instance name specified. The stop-instance can be run both locally and  remotely.   The
       named instance must already exist within the given domain; and the instance must be running.

OPTIONS

       --user		       administrative user associated for the instance.

       --password	       administrative password corresponding to the administrative user.

       --host		       host name of the machine hosting the administrative instance.

       --port		       administrative port number associated with the administrative host.

       --local		       determines if the command should delegate the request to administrative instance or run locally.

       --domain 	       name of the domain.

       --passwordfile	       file containing passwords appropriate for the command (e.g., administrative instance).

       --secure 	       if true, uses SSL/TLS to communicate with the administrative instance.

OPERANDS

       instance_name	       name of the instance to be stopped.

       Example 1: Using stop-instance in local mode

       asadmin> stop-instance --local --domain domain1 server1
       Instance server1 stopped

       Where: the server1 instance associated with the domain1 domain is stopped locally.

       Example 2: Using stop-instance in remote mode

       asadmin> stop-instance --user admin --password bluestar --host localhost --port 4848 server1
       Instance server1 stopped

       Where: the server1 instance associated with the named user, password, host and port is deleted from the remote machine.

EXIT STATUS

       0		       command executed successfully
