Using Tables in some package configuration problem

[Max Leuthäuser]

I want to use the Tables Object in some.package.models
instead of the default models.

My db application config looks like:

[... more ...]
dev {
  schema = "some.package.models.Tables"
  driver = "org.h2.Driver"
  jdbcurl = "jdbc:h2:mem:test"
  autoCreate = true
  autoDrop = true
  user=sa
  password=""
}
[... more ...]

Still it complains with:

What is going wrong here?

Alternative config might look like:

db.activerecord.driver=org.h2.Driver
db.activerecord.url="jdbc:h2:mem:play"
db.activerecord.user=sa
db.activerecord.password=""
schema.some.package.models.Tables=activerecord

But fails with:
