Abstract

Building a package for installing a software application on a data processing system with a distributed architecture is provided. The installation package is built using an authoring tool based on a declarative model. A descriptor is used to define a desired configuration of the system. The installation package is built declaring a discoverer element, a producer element and a consumer element into the wizard tree. During the installation process, the discoverer element detects a current configuration of the system. The producer creates a working queue dynamically, inserting the installation operations that are needed for reaching the desired configuration from the current configuration of the system. The producer then executes the installation operations defined in the working queue. In this way, the installation operations are determined at runtime.
