The present invention is directed to the automatic configuration of portal composite applications. A method for automatic configuration of a portal composite application including a portal composite application infrastructure, wherein configuration parameters are managed within a composite application interface of the portal, which interface defines a runtime behavior of instances of the composite application within a predetermined range of variability, and wherein each parameter defines a respective point of variability, includes: storing a collection of parameter values for each of the points of variability; defining a functional component cooperating with the composite application and having read access to the collection of parameter values; invoking the functional component after or at instantiation time of the composite application, yielding a configuration parameter value; including the configuration parameter value into a control for an instance of the composite application; and automatically configuring the instance of the composite application with the included configuration parameter value.

System and method for automatic configuration of portal composite applications

A predetermined business task of a composite application can be fulfilled. The composite application can include a set of components. The composite application is instantiated by a template means and a predefined collaborative context module controls the interaction of the set of components during the runtime of the composite application. A set of components fulfilling individual services on individual different server systems is leveraged by the composite application. During the instantiation of the composite application from a template, the referenced components (as types) are instantiated leading to runtime instances of these components. The interaction of the different components is controlled on individual different server systems utilizing a primary context module. The primary context module communicates with an appropriate collaborative module implemented locally on the respective set of servers, where the local context modules act as secondary context modules in relation to the primary context modules. For each of the secondary context modules, local components communicate to control the interaction of components.

Federation of composite applications

The present invention relates to the field of network portals and in particular to a method and system for exchanging data between components of one or more composite applications implemented on a portal server, wherein the components are programmed independently from each other. An embodiment of the invention includes: automatically intercepting I/O data being input or output respectively to or from the components or a browser; extracting data objects from the I/O data; determining for a source component, which of the data objects match input requirements of which other potential target components; selecting matching data objects for a matching target component; and transferring the matching data objects to the matching target component.
