For best performance, an application can minimize loading time by downloading components as needed. To enable this scenario, the ArcWeb Explorer application framework is implemented using modules. For the best experience in managing these components, the ArcWeb Explorer application framework implements the Open Services Gateway initiative (OSGi) framework for service management. With the OSGi framework, the modules can be downloaded and activated as needed. The ArcWeb Explorer application framework wraps all this in an easy-to-use Flex API, so end developers can leverage the advantages of these capabilities with minimal time and effort.
