How to access the development database with the Play! framework?
Log on to the JDBC URL jdbc:h2:mem:play instead. That is where the development database runs on at least on my Play instance.
Most likely, you are looking a different database. Could you verify the database URL is really jdbc:h2:~/play?
You should also consider upgrading to a more recent version of H2. The version you are using (1.3.149) is a beta version.
