ABSTRACT:
A class loader downloads objects and object viewers from remote computer nodes, and invokes locally stored object viewers to view objects. When a user selects an object to view, a conventional downloading of the referenced object is initiated. The class loader, however, utilizes data type information received at the beginning of the object downloading process to determine if a viewer for the referenced object is available on the user's workstation. If an appropriate view is not locally available, the class loader automatically locates an appropriate viewer on the server from which the object is being downloaded, or from any other appropriate server known to the user's workstation. The class loader downloads the located viewer and then invokes a program verification procedure to verify the integrity of the downloaded viewer before the viewer is executed. Once a viewer has been verified, the viewer is added to the user's local viewer library, downloading of the referenced object is completed, and execution of the viewer to view the downloaded object is enabled. If an appropriate viewer cannot be located, or the only viewer located does not pass the verification procedure, downloading of the referenced object is aborted.
