Abstract

A handheld client framework system provides a server proxy client that services client requests for network accessible information and determines the server that is most appropriate to supply the requested information and sends information request packets to that server across the Internet and/or intranet. Server responses to information requests are received by the server proxy client. The server proxy client separates the response information into the appropriate data components. Data components are sent to the appropriate client. Presentation and logic components are temporarily stored in a one-behind cache on the client. A client will continue to use the presentation and logic components already installed or in the one-behind cache to service the current user request. Any updates sent by the server proxy client and stored in the one-behind cache are retrieved by the client upon subsequent use by the user. The state of the client is saved by the server proxy client so that the client is not dropped when a user, for example, changes from a wired connection to a wireless connection. The invention includes a scripting language that supplies the logic component of the client and gives the client unlimited flexibility by allowing the host to modify the client'"'"'s behavior or add new features at any time.

Claims

sending said client request to said proper server;

receiving said proper server'"'"'s response to said client request;

wherein said server proxy client acts as a proxy client for said client system, performing the bulk of data processing for said client system;

wherein said server proxy client updates said client system with data, presentation, and logic components using a universal data format;

wherein said server proxy client separates raw data from presentation aspects of said response and places said data into said universal data format;

sending said data to said client system;

wherein said server proxy client receives presentation and logic component updates; and

wherein said presentation component updates are for a specific client device type.

2. The process of claim 1, wherein said logic component updates are shared between different client device types.

3. The process of claim 1, further comprising the step of:

providing a one-behind cache on said client system; and

wherein said client system checks said one-behind cache for any presentation or logic components relating to a user'"'"'s request;

wherein if any components relating to a user'"'"'s request exists in said one-behind cache, said client system checks if said components have expired;

wherein said client system uses said components to service the user'"'"'s request.

4. The process of claim 3, wherein if said components have expired, said client system requests any current versions of the expired components from said server proxy client, wherein said server proxy client checks the current version of a requesting client'"'"'s presentation and logic components, if any of the presentation and logic components requires updating, then said server proxy client retrieves the latest version of any of the presentation and logic components and sends it to the requesting client, and wherein the requesting client stores the latest version of any of the presentation and logic components in said one-behind cache.

5. The process of claim 1, further comprising the step of:

sending said presentation and logic component updates to a client system.

6. The process of claim 1, wherein said client system uses said data and presentation components to create displays to a user.

7. The process of claim 1, wherein said client system reuses said data component for other display purposes.

8. The process of claim 1, further comprising the step of:

providing means on said server proxy client for saving a client system'"'"'s state on storage device; and

wherein the saved client system'"'"'s state allows said server proxy client to continue a client system'"'"'s session when the client system changes connection methods to or loses coverage with said server proxy client.

9. The process of claim 1, further comprising the step of:

providing a scripting language;

wherein said logic component updates are written in said scripting language;

wherein said server proxy client compiles scripts written in said scripting language into executable bytecodes;

wherein said server proxy client updates said client system'"'"'s features by sending said client system said executable bytecodes; and

wherein said client system executes said executable bytecodes in response to a user'"'"'s input.

10. The process of claim 9, wherein a client system'"'"'s presentation aspects are controlled using said scripting language.

11. The process of claim 1, wherein communication between said server proxy client and said client system is via a binary encoding of an XML data stream.

12. A process for dynamically configuring client systems, comprising the steps of:

providing a host server;

providing a scripting language;

wherein said host server compiles scripts written in said scripting language into executable bytecodes;

wherein said host server, upon receipt of a request for specific up to date presentation components and/or executable bytecodes from a client system, checks if the client system'"'"'s original presentation components and/or executable bytecodes have expired;

wherein said host server updates the client system'"'"'s features by sending the client system updated presentation components and/or executable bytecodes if the original presentation components and/or executable bytecodes on the client system have expired; and

wherein a client system executes presentation components and/or executable bytecodes in response to a user'"'"'s input.

13. The process of claim 12, wherein said scripts define program logic.

14. The process of claim 12, wherein said scripts create and control user interface displays.

15. The process of claim 12, wherein said client system receives requested network information from said host server separated into data and presentation components.

16. An apparatus for a framework architecture for client systems, comprising:

a server proxy client;

means on said server proxy client for receiving a client information request from a client system;

server determination means on said server proxy client for determining the proper server to service said client request;

a module for sending said client request to said proper server;
