Examples of net.sourceforge.stripes.config.BootstrapPropertyResolver

net.sourceforge.stripes.config.BootstrapPropertyResolver
Resolves configuration properties that are used to bootstrap the system. Essentially this boils down to a handful of properties that are needed to figure out which configuration class should be instantiated, and any values needed by that configuration class to locate configuration information.

Properties are looked for in the following order:
- Initialization Parameters for the Dispatcher servlet
- Initialization Parameters for the Servlet Context
- Java System Properties
