Use of the com.bukkit namespace is forbidden - that is what is causing the error.
Change the namespace to something else, both in your classes and in the plugin.yml

You need to register the command on the yml file like this:
Code:
commands:
  am:
    description: AdminMod
    usage: |
      /<command> - Do something.

. thx but it works not

You have many errors on your src man, lets see:
The cmd is not on "String name" is on "Command c" So:
Code:
if(c.equals("adminmode") || c.equals("am"))
and them you have "adminmod" and "am" use just "am" and register "adminmode" as an command alias
Code:
if(c.equalsIqnoreCase("am")))
Code:
commands:
  am:
    description: AdminMod
    usage: |
      /<command> - Do something.
    aliases: [adminmod]
There maybe more errors but I must go now...
Cheers

Your error is you're developing with a different Bukkit build than your server is running.
This is what you should be using:
CraftBukkit: http://ci.bukkit.org/job/dev-CraftBukkit/556/
Bukkit: http://ci.bukkit.org/job/dev-Bukkit/461/

In the future, to tell what version of Bukkit to download to develop with, look on the CraftBukkit page of the CI, and at the bottom it says "Upstream Builds", just download that copy of Bukkit
