METHOD AND APPARATUS FOR UPDATING AND SYNCHRONIZING INFORMATION BETWEEN A CLIENT AND A SERVER

摘要

The present invention integrates applets running on a client with the application logic for applications running on a server. In the described embodiments, a hidden Applet Group Controller applet handles communication between the applets on the browser and the application logic on the server. The Applet Group Controller maintains an association with each applet that includes the keys and values of any parameters and variables for the applet. Upon the invocation of an event, the association instructs an Action Coordinator to invoke an action. The Action Coordinator obtains and transmits a list of all of the keys and their values to the server. The server invokes the appropriate application logic and transmits the keys and their values (as updated during the execution of the application logic) back to the Action Coordinator, which pushes the updated values out to the applets and the browser's display is updated.
