Abstract

A system and method for simultaneously displaying a set of display applets while optimizing the number of server connections. A connection to the server is established by a controlling applet. The controlling applet receives data from the server, parses the data, transmits the data to a set of display applets, and displays the set of display applets on a single browser window. Even if an applet is torn off a single browser window and moved to another window, the controlling applet continually maintains a link to the server to continually update the data values on the torn off applet as well as on the set of display applets on the single browser window.

Claims

1. A method of providing data to a plurality of display applets comprising the steps of:

creating a client applet above an applet class for inter-applet communication with a plurality of display applets;

initializing said plurality of display applets;

establishing a connection from a client to a server by a controlling applet;

sending a data request from said client to said server by said controlling applet;

reading an identification string from each one of said plurality of display applets by said controlling applet;

transmitting a keyword and data from said server to said controlling applet;

parsing said data in the controlling applet;

comparing said identification string to said keyword by said controlling applet;

sending said data by said controlling applet to said plurality of display applets based on the results from said step of comparing said identification string to said keyword; and

updating and displaying said plurality of display applets.

2. The method as recited in claim 1 wherein said step of updating and displaying said plurality of display applets is performed on a single browser window on a Web page.

3. The method as recited in claim 2 further comprising the step of moving one of said plurality of display applets to another window.

4. The method as recited in claim 1 wherein said plurality of display applets are updated with said data by said controlling applet.

5. The method as recited in claim 1 wherein said controlling applet sends said data to said plurality of display applets.

6. The method as recited in claim 1 wherein said connection is performed in a thread.

7. The method as recited in claim 1 wherein said controlling applet inherits a set of functions from said applet class.

8. The method as recited in claim 1 wherein said data comprises of any structured data understood by said controlling applet.

9. The method as recited in claim 1 wherein said step of displaying said plurality of display applets comprises displaying six display applets on said single browser window on said Web page.

10. The method as recited in claim 1 wherein said step of sending a data request from said client to said server by said controlling applet is repeated after a selected period of time.

11. A method of providing data to a plurality of display applets comprising the steps of:

establishing a connection from a client to a server by a controlling applet;

transmitting data from said server to said controlling applet;

sending said data by said controlling applet to a plurality of display applets; and

updating and displaying said plurality of display applets.

12. The method as recited in claim 11 further comprising the step of reading an identification string from said plurality of display applets by said controlling applet.

13. The method as recited in claim 12 wherein said data comprises a keyword and further comprising the step of comparing said identification string to said keyword by said controlling applet.

14. The method as recited in claim 11 wherein said data comprises a keyword, a numerical value, and an end of data indicator.

15. A computer program product for providing data to a plurality of display applets, said product comprising:

code that creates a client applet above an applet class for inter-applet communication with a plurality of display applets;

code that establishes a connection from a client to a server by a controlling applet;

code that reads an identification string from each one of said plurality of display applets by said controlling applet;

code that transmits a keyword and data from said server to said controlling applet;

code that compares said identification string to said keyword;

code that sends said data by said controlling applet to said plurality of display applets; and

a computer-readable medium for storing said codes.

16. The computer program product as recited in claim 15 further comprising code that parses said data in said controlling applet.

17. The computer program product as recited in claim 15 further comprising code that updates and displays said plurality of display applets.

18. The computer program product as recited in claim 15 further comprising code that initializes said plurality of display applets.

19. The computer program product as recited in claim 15 further comprising code that sends a data request from said client to said server by said controlling applet.
