I don't understand the jndiName whether the jndiName is whatever

Hi,
This line configures the database connections:
I think there might be a problem with the way you are specifying which
db to use in your mapper classes. Here's the relevant text from the
The Lift Book:
dbSelect... is used to find an instance by primary key, and takes a
partial function (typically a match clause) to determine which
connection
Yeah, i don't want to use sharding, i just want select some
information from another databases,

It doesn't work, maybe the code that i write is wrong ?
I did some more digging and got a sample app to work. You can see the code here:
http://github.com/eltimn/lift_1_1_sample
There are 2 things I had to do. The first is to pass in the DbId when
calling Schemifier;
Schemifier.schemify(true, Log.infoF _, OneDB, User)
Schemifier.schemify(true,
Thanks Tim,
I have tried it in my code but it doesn't work yet!
The lift version is: 1.1-M7
Scala Version is: 2.7.7

It works now, I missing the dbDefaultConnectionIdentifier definition
in the others models.
Thank you very much!

Hi all,
I want to use two databases, but i don't know how to configure it.
Does anybody know that how to configure two
I haven't used multiple connections myself, but I think you have two issues,
1) The default connection identifier is lift so you have to define a
connection with that name otherwise you'll have to override all Mapper
objects to use a different connection.
2) Your dbCalculateConnectionIdentifier
The two databases that have different structure of the tables, such
as two applications databases.
