Abstract

A portal server presents an HTML page that comprises a plurality of modules. Each module represents a network resource that can be accessed by a user through the portal. The portal server includes an administration interface that enables an administrator to select from various layout styles. A variety of modifications can be done to the portal without requiring programming skills. An updateable subsystem class is configured to instantiate an update subsystem object. The update subsystem object is operable to select an updated implementation of module from a set of update servers. An appropriate update server is selected from a set of update servers based on host identification information of a site hosting the portal including the module.

Claims

1. A portal server framework for modifying modules within a portal on a computer network, comprising:

an intermediate class configured to instantiate an intermediate object, the intermediate object operable to hold a reference to a current implementation of an instantiated object, the instantiated object encapsulating information of a particular type on the computer network; and

an updateable subsystem class configured to instantiate an update subsystem object, the update subsystem object operable to select an updated implementation of the instantiated object from a set of update servers;

whereby, an appropriate update server in the set of update servers from which to select the updated implementation of the instantiated object is based on host identification information of a site hosting the portal, and upon installation on the network, the classes are executable by a processor on the computer network.

2. The portal server framework of claim 1, further comprising a portal module upgrade servlet class configured to instantiate a portal module upgrade servlet object, the a portal module upgrade servlet object operable to deliver a file to the update system object from the appropriate update server in the set of update servers.

3. The portal server framework of claim 2, wherein the file includes a combination of. a class file, an image file, a sound file and data information file.

4. The portal server framework of claim 3, further comprising a dynamic loader class configured to instantiate a dynamic loader object, the dynamic loader object operable to retrieve a set of classes for the updated implementation of the instantiated object.

5. The portal server framework of claim 4, further comprising a swappable loader class configured to instantiate a swappable object, the swappable object operable to provide the set of classes for the updated implementation of the instantiated object to the intermediate object.

6. The portal server framework of claim 5, wherein the intermediate object replaces the reference to the current implementation of the instantiated object with a reference to the updated implementation of the instantiated object.

7. The portal server framework of claim 1, further comprising a portal module upgrade servlet class configured to instantiate a portal module upgrade servlet object, the portal module upgrade servlet object operable to deliver a properties object to the update system object from the appropriate update server in the set of update servers.

8. The portal server framework of claim 7, wherein the properties object includes a combination of the location of:

a file, a class name of the updated implementation of the instantiated object, a title of the updated implementation of the instantiated object, a description of the updated implementation of the instantiated object, and an updated implementation of the instantiated object.

9.

a class file, an image file, a sound file and data information file.

13. The method of claim 12, further comprising providing a dynamic loader class configured to instantiate a dynamic loader object, the dynamic loader object operable to retrieve a set of classes for the updated implementation of the instantiated object.

14. The method of claim 13, further comprising providing a swappable loader class configured to instantiate a swappable object, the swappable object operable to provide the set of classes for the updated implementation of the instantiated object to the intermediate object.

15. The method of claim 14, wherein the intermediate object replaces the reference to the current implementation of the instantiated object with a reference to the updated implementation of the instantiated object.

16. The method of claim 10, further comprising providing a portal module upgrade servlet class configured to instantiate a portal module upgrade servlet object, the portal module upgrade servlet object operable to deliver a properties object to the update system object from the appropriate update server in the set of update servers.
