using with mysql connector 5, unable to open connection on beginTransaction

[Ka-Wai Chan]

Hello
 
I am using the mysql .net connector 5 with Ibatis.Net and everything works 
great (insert, update, find) except when I try to call 
mapper.BeginTransaction() in which case it then can't open the connection.
 
Any ideas?
 
Thanks
