Abstract

A method and apparatus for operating a local server computer of a client-server network includes a technique to receive a request from a client computer of the client-server network. A determination is made whether the request requires dynamically generated information from a servlet object of the client-server network. If so, a specified servlet object corresponding to the request may be uploaded from a remote server computer of the client-server network. The specified servlet object is then executed to obtain dynamically generated information corresponding to the request.

Claims

1. A method of dynamically generating information using a server computer of a client-server network, the method comprising:

receiving, at said server computer, a request from a client computer of the client-server network;

determining that said request requires dynamically generated information from a servlet object of said server computer;

executing said specified servlet object to obtain dynamically generated information corresponding to said request; and

communicating said dynamically generated information from said servlet object to said client computer.

2. The method of claim 1, wherein said servlet object is implemented as object bytecodes in the JAVA programming language.

3. The method of claim 1, wherein said communicating comprises:

passing said dynamically generated information from said specified servlet object to a web server operation on said server computer, said passing step being facilitated by an application programming interface; and

sending said dynamically generated information from said web server to said client computer.

4. The method of claim 1, further comprising, at start-up of said server computer, instantiating a plurality of servlet objects, each of said plurality of servlet objects continuously operating until invoked in response to a specified request from a client computer.

5. The method of claim 1, further comprising instantiating said servlet object in response to said request form said client computer.

6. The method of claim 1, further comprising instantiating said servlet object in response to an activated servlet URL.

7. The method of claim 6, wherein said activated servlet URL comprises arguments.

8. A computer readable memory that can be used to direct a server computer of a client-server computer network to function in a specified manner, comprising:

a first set of instructions to receive, at said server computer, a request from a client computer of said client-server network;

a second set of instructions to determine that said request requires dynamically generated information from a servlet object of said server computer;

a third set of instructions to execute said specified servlet object to obtain dynamically generated information corresponding to said request; and

a fourth set of instructions to communicate dynamically generated information from said servlet object to said client computer.

9. The computer readable memory of claim 8, wherein said servlet object is implemented as object bytecodes in the JAVA programming language.

10. The computer readable memory of claim 8, wherein said fourth set of instructions comprise:

instructions to pass, through an application programming interface, dynamically generated information from said servlet object to a web server operating on said server computer; and

instructions to send said dynamically generated information from said web server to said client computer.

11. The computer readable memory of claim 8, further comprising a set of instructions to instantiate a plurality of servlet objects at start-up of said server computer, each of said plurality of servlet objects continuously operating until invoked in response to a specified request form a client computer.

12. The computer readable memoru of claim 11, further comprising a set of instructions to pass data between said plurality of servlet objects.

13. The computer readable memory of claim 8, further comprising a set of instructions to instantiate said servlet object in response to said request from said client computer.

14. The computer readable memory of claim 8, further comprising a set of instructions to instantiate said servlet object in response to an activated servlet URL.

15. The computer readable memory of claim 14, wherein said activated servlet URL comprise arguments.
