Clear players Chat

Can someone tell me the way to clear the Players Chat?

I want the following:

I send something (player.sendmessage(....)),
i clear the text in chat (so nothing is in the Chat),
i send another player.sendmessage(...)

so i actually only need a clear-command.

Is such a comamnd available in bukkit?

Thanks in advance

 

just do this:

Code:JAVA

 
for(int i=0;i<20;i++)
player.sendMessage("");

 

Hmm, okay, thanks

Doesn't exist a method?

edit*
If i use this the chat has his backcolor :/
It doesn't look good..

Are there other methods, which doesn't make the backcolor?
(The grey/braun background behind the Text)

 

No, because the GUI is client side. It is possible with Spout, though.

 

And how exactly?

I will google it tomorrow, now i have to sleep
