The <installList> element is a child of the <component> element and contains one or more named install step blocks, each providing a different way to install this component. Many components will have only one install block as a child of this element.
Multiple install blocks can be used when different steps are required for different installation environments. For example, steps to deploy an EBJ app to a server cluster versus deploy to a single managed server, or steps to install for the first time versus steps to upgrade the application.
