Connecting to 2 database - best practices?

[Brian Kierstead]

Hi everyone,

I need to integrate 2 databases into my current application - sql server 
2005 and ingres II.

Have any of your set this up before?  What is the best way to configure 
iBatis to handle this? 

I'm using a tiered architecture similar to that in the NPetShop 
application.  To what layer should the change go - Persistence and 
Service or just Persistence? 

Or can the dao.config and sqlMap.config manage all the necessary 
connections on their own?

Thanks,
Brian
