<p>The method involves using computers distributed in a network. Each computer provides a platform for the execution of mobile software agents for the instantiation of an object of a version-specific class. If a certain version of the class is requested, the requested version is searched, otherwise the newest version of the class is used. The platform searches whether this newest version is already locally available, otherwise the class definition of the corresponding version is requested from the class file server. If the class definition of the corresponding, demanded version is not already locally available, the definition is searched for, and if it is not found, the instantiation is not performed. The object is instantiated according to the version of the class definition to be used.</p> |
