      Description

      I'd like to create a ResourceLoader similar to DataSourceResourceLoader, except that I'd like to set
      the DataSource via IoC (in Spring). The main reason for this is so my database-loading of templates
      does not depend on a JNDI connection.

      The main problem is how to manage a ResourceLoader with Spring and then set it declaratively on its
      VelocityEngine - rather than via properties.

      <suggested patch from Will Glass-Husain>
      Does this mean that you'd need to pass in an instance of a resource manager
      (initialized with the datasource) to VelocityEngine, rather than just set
      the class name as a property? (MR - Yes)

      As I understand the source code, this doesn't seem possible. But I think a
      patch wouldn't be difficult. (a change to
      RuntimeInstance.initializeResourceManager) to look for an instance of the
      class as well as the class name. Something similar to
      LogManager.createLogSystem which accepts as a property the class name of a
      class that implements LogSystem, or an instance of the class itself.
      </suggested patch>
