In response to a message requesting a method invocation from an application or user, a client application determines the proper method to be invoked by retrieving information from a class data base, comparing the retrieved information with user preferences, and selecting the proper method based upon the comparison. Server connection and start-up involves locating a platform capable of executing code associated with the selected method and, if necessary, executing a process to start an application associated with the selected method.
