ACTIVE_ENV
is not provided, the framework defaults to "development".
1. public class DbConfig extends AbstractDBConfig { 2. public void init() { 3. environment("development").jndi("jdbc/kitchensink_development"); 4. environment("development").testing().jdbc("com.mysql.jdbc.Driver", "jdbc:mysql://localhost/kitchensink_test", "root", "****"); 5. environment("hudson").testing().jdbc("com.mysql.jdbc.Driver", "jdbc:mysql://172.30.64.31/kitchensink_test", "root", "****"); 6. environment("production").jndi("jdbc/kitchensink_production"); 7. } 8.}The code above is an example from Kitchensink project.
