I'm new to this mailing list so forgive me all my mistakes (or repeated
question?).
I'm trying to use Cayenne with MSSQL Server 2005. I downloaded the fresh
jdbc driver, created the database, set up new user with password. After
designing the tables in the Cayenne Modeler i generate database and
everything goes fast. I checked manualy if the database exists and so on
(with the mssql management tools) and everything seems to be fine.Then I
generate classes, write some simple query and here the problem starts. It
takes great amounts of time for application to connect to the database. It
can take up to 20s when im running first query:

It doesn't matter what query (insert,update,select) im trying to run. Always
stops at the same place and if there is an exception (usually there is) it
looks like the one i posted. I think that its about commitChanges() but i
dont know what is causing he problem. Would love to hear your advices :)
Thank you for all your help and im sorry for my poor english :)
Mike
