Project

The database must support many projects, not only 'Br' , so...

 CREATE TABLE `project` (
 `id` int(10) unsigned NOT NULL auto_increment,
 `name` varchar(50) NOT NULL,
 `description` mediumtext NOT NULL,
 `creation` datetime default NULL,
 `modified` timestamp NOT NULL default CURRENT_TIMESTAMP on update CURRENT_TIMESTAMP,
 PRIMARY KEY  (`id`),
 UNIQUE KEY `name` (`name`)
 ) ENGINE=InnoDB DEFAULT CHARSET=latin1 

must think how I will link this stuff... JSP: i should implement a custom iterator tag for CloseableIterator

ok, done: http://code.google.com/p/code915/source/browse/trunk/core/src/java/fr/inserm/umr915/core/j2ee/tag/IteratorTag.java
