Hi all

I've created an application in Seam using Hibernate tools.
But when I tried to call the persist method, it leads to an exception
"No CurrentSessionContext configured!"
can anybody help me?

hai all
i am getting an exception like
MySQLSyntaxErrorException multiple primary key defined.
my query is

CREATE TABLE `first_item` (
`itemid` int(5) unsigned NOT NULL default '0',
`subitemid` int(5) unsigned NOT NULL default '0',
PRIMARY KEY (`itemid`,`subitemid`)
)
i am using innodb as the database engine.
can someone give me any suggestion please.

thanks
