Unitils and DBMaintainer - how to make them work with multiple users/schemas?

Question

I am working on a new Oracle ADF project, that is using Oragle 10g Database, and I am using Unitils and DBMaintainer in our project for:

• updating the db structure
• unittesting
• read in seed data
• read in test data
• List item

In our project, we have 2 schemas, and 2 db users that have privilegies to connect to these schemas. I have them in a folder structure with incremental names and I am using the @convention for script naming.

001_@schemaA_name.sql 
002_@schemaB_name.sql 
003_@schemaA_name.sql 

This works fine with ant and DBMaintainer update task, and I supply the multiple user names by configuring extra elements for the ant task.

<target name="create" depends="users-drop, users-create" description="This tasks ... ">
    <updateDatabase scriptLocations="${dbscript.maintainer.dir}" autoCreateDbMaintainScriptsTable="true">
       <database name="${db.user.dans}" driverClassName="${driver}" userName="${db.user.dans}" password="${db.user.dans.pwd}" url="${db.url.full}" schemaNames="${db.user.dans}" />
        <database name="idp" driverClassName="${driver}" userName="${db.user.idp}"
            password="${db.user.idp.pwd}" url="${db.url.full}" schemaNames="${db.user.idp}" />
    </updateDatabase>
</target>

However, I cant figure out, how to make the DBMaintainer update task create the xsd schemas from my db schemas?

So, I decided to use Unitils, since its update creates xsd schemas. I haven't found any description or documentation for the Unitils ant tasks - can anyone give some hints? For the time being I have figured out to run Unitils by creating a Junit test, with @Dataset annotation. I can make it work with one schema, and one db user. But I am out of ideas how to make it work with multiple users?

Here is the unitils-local.properties setup I have:

database.url=jdbc\:oracle\:thin\:@localhost\:1521\:vipu
database.schemaNames=a,b
database.userName=a
database.password=a1

Can any of you guys give me a tip, how to make Unitils work with the second user/schema ?? I will be extremely gratefull for your help!

I have figure out how to make dbmaintain and unitils work together on multi-database-user support, but the solution is a pure ant hack.

1. I have set up the configuration for dbmaintain, using multi-database-user support.
2. I have made a unitils-local.properties file with token keys for replacement.
3. The init target of my ant script is generating a new unitils-local.properties file, by replacing tokens for username/password/schema with values that are correct for the target envirnonment, and then copies it to the users home directory.
4. I have sorted the tests into folders, that are prefixed with the schema name
5. When unitils is invoked, it picks up the unitils-local.properties file just created by the ant script, and does its magic.

Its far from pretty, but it works.
