A few Errors. Any help is appreciated.

Hello,
I've just started work on a plugin for the latest bukkit build.
I followed an old-ish guide on how to find my way around bukkit, anyway, i had it working yesterday, but when i typed a command, eg. /balance
It would not show my balance. Even though it said all was fine and dandy, in console.

I have tried again and now..

You can't use com.bukkit.* for the package, is't saved for bukkit devs !

 

Side note, if you're using an old guide for player commands, make sure you're not using PLAYER_COMMAND since it won't work anymore, use onCommand instead.

 

It doesn't? Thought he mentioned that wasn't true, but that the onCommand was just new and ready to be used. My server still works like a charm though.

 

New versions, [454+] I believe, of craftbukkit have gotten rid of the PLAYER_COMMAND hook.

 

Yes that's true too, and you may be getting the TSLPC error too

 

oh the com.bukkit.* (had no idea), thanks.
And i was using the PLAYER_COMMAND, but i noticed it wasn't there anymore, i could only find player_command_preprocess.
I don't think it was in there the last time i ran the plugin.
