Freezing mobs with command help

Hello, I am here today to ask of you of how I freeze mobs with a command, for instance if you typed /freeze, it would freeze the mob you're looking at. This is the code I got so far. I'm new to bukkit coding so I wouldn't know how to do this.

Code:

import org.bukkit.craftbukkit.v1_5_R2.entity.CraftLivingEntity;
import org.bukkit.entity.Player;
import org.bukkit.plugin.PluginManager;
import org.bukkit.plugin.java.JavaPlugin;
 
public class RemovePotionParticles extends JavaPlugin {
 
    public RemovePotionParticles plugin;
   
    public void onEnable() {
        startTask();
        getLogger().info("RemovePotionParticles is active and ready.");
    }
   
    public void onDisable() {
    }
 
    private void startTask() {
        long interval = 4;
        getServer().getScheduler().scheduleSyncRepeatingTask(this,
                new removeParticle(), interval, interval);
    }
 
    private void endTask() {
        getServer().getScheduler().cancelTasks(this);
    }
 
    private class removeParticle implements Runnable {
 
        public void run() {
            for (Player player : getServer().getOnlinePlayers()) {
                ((CraftLivingEntity) p).getHandle().getDataWatcher().watch(7, 0);
            }
        }
    }
}

 

You actually want to add the command using the code here:

Code:java

public boolean onCommand(CommandSender sender, Command cmd, String label, String[] args){
if(cmd.getName().equalsIgnoreCase("basic")){ // If the player typed /basic then do the following...
// doSomething
return true;
} //If this has happened the function will return true.
// If this hasn't happened the a value of false will be returned.
return false;
}

This is just a example, just paste it into Eclipse if this is what your using and use it as a template. If you get stuck just say.

If you are new to bukkit I would suggest referring to the wiki which is where I copied that from. You can see it Here. Good luck with your plugin pal!
