4.2.6. environment.xml file

The default environment.xml file created during the installation of Nova Orchestra is set to use the database implementation of the persistence service. This file also sets the configuration of hibernate. Here is the environment.xml file generated :

<environment-definition>

  <application>
    <hibernate-session-factory table-prefix='NOVA_'>
      <properties resource='hibernate.properties' />

Currently, following objects implementations can be injected in the environment:

* Note 1: As explained before persistence objects are provided as default implementations in the environment. Notice that in a persistence configuration additional resources are required, i.e for hibernate persistence you can specify mapings, cache configuration...

* Note 2: The environment is divided in two different contexts: application and block. Objects declared inside the application context are created once and reused while objects declared inside the block context are created for each operation.
