Help with command.

My plugin loads fine, when i issue the command /hello, all that comes up is /hello.
And when my plugin is enabled, it automatically disables!
Here is my .class file

Code:java

ackage name.testplugin;
 
import org.bukkit.plugin.java.JavaPlugin;
import org.bukkit.ChatColor;
import org.bukkit.entity.Player;
import org.bukkit.command.Command;
import org.bukkit.command.CommandSender;
import org.bukkit.event.Listener;
 
public class Main extends JavaPlugin{
 
public void onEnable(){
getLogger().info("Enabled!");
}
 
public void onDisable(){
getLogger().info("Disabled!");
}
public boolean onCommand(CommandSender sender, Command cmd, String label, String[] args) {
Player player = (Player) sender;   
if(cmd.getName().equalsIgnoreCase("hello")){
player.sendMessage(ChatColor.AQUA + "Hello Minecraft!");
}
return true;
}
}

 

Hello,

can you show us the server log from startup to where your plugin "disables automatically" ?
