Abstract

Method, system, and computer program product for instantiating a template in a composite application infrastructure. A template that describes a composite application having a plurality of application components is created. The template includes a composite application component assembly descriptor which lists each application component of the composite application. The template is stored in a template library. The composite application is instantiated using the template for creating at least one composite application instance. In an application instance registry, composite application instance(s) and instance information related to the composite application instance(s) is/are registered. The composite application instances are transiently represented in the application instance registry by a respective table entry without creating a real object. The real object that is dynamically created represents a particular composite application instance during a composite application usage session. At an end of the composite application usage session, the particular unused composite application instance is removed.
