Message System

Pauler · August 27, 2012

Hello there summoners.

Untill now, I haven't shared anything coded in Java. So I decided to code and share a message system (or mail system). It gives the possibility to players to send messages to each other even if the recipient is offline. Coded in l2jfrozen.

Message System L2J

First, run this code at your mysql:

DROP TABLE IF EXISTS `mails`;
CREATE TABLE `mails` (
  `id` int(11) NOT NULL AUTO_INCREMENT,
  `from` text,
  `to` text,
  `title` text,
  `message` text,
  PRIMARY KEY (`id`)
) ENGINE=InnoDB AUTO_INCREMENT=43 DEFAULT CHARSET=latin1;

Core Side:

### Eclipse Workspace Patch 1.0
#P L2jFrozen_GS
