(URGENT) multiple hibernate configuration files and DiffDatabaseTask

Hi every body,
I want to execute DiffDatabaseTask with Ant but the problem is that I have three hibernate.cfg files each for one module in my application and I don’t know how to put them into diffChangeLog task, so I decided to get configuration from application context and send it to HibernateDatabase to continue with that instead of getting resource as stream.

can anyone help me?

Which version of liquibase are you running?  There is significant changes between 1.9 and 2.0 and how the Database and Snapshot objects work.  I would suggest going with 2.0 at this point to reduce rework in the future.
