That's how I currently have it implemented. If you are using a singleton for your mapper, you could probably cache it there as well.

If I understand your approach, that will only work if all methods are in the same class, correct? -----Original Message----- From: Bob Hanson [mailto:[EMAIL PROTECTED] Sent: Thursday, February 22, 2007 3:37 PM To: [email protected] Subject: Re: Checking for Open Transactions It looks like_isOpenTransaction is never set to false once it becomes true. So adding a property is not enough. Right now I have decided to hold on to an instance of ISqlMapSession when I start a transaction that I want to share across method calls. If my session instance is not null, I use that session. If it is null, I start a new local transaction instead.
