Abstract

A system (30) and method are provided for single-pass execution of dynamic pages across multiple request-response cycles. The system (30) comprises a client (32) and server (34) in communication with one another. A container (35) resides on the server and handles requests made for the result of a dynamic page (36). The container controls the processing of the dynamic page. If the dynamic page requires additional information to continue processing, an intermediate request (44) is transmitted to the client, which responds with an intermediate response (46) containing the additional information. A notifier servlet (38) receives the intermediate response and passes the information to the dynamic page so that execution can resume without interruption.

Claims

1. A method for executing a dynamic page on a server-side computer in a client-server environment, comprising:

receiving a request from a client for execution of said dynamic page in a dynamic webcontent execution environment on said server-side computer;

initiating execution of said dynamic page in said dynamic webcontent execution environment on said server-side computer, wherein said dynamic page includes a plurality of code blocks each requiring input from said client in series and to be executed in series;

at each instance when said executing dynamic page requires additional information for one of said plurality of code blocks from said requesting client to continue execution, then;

transmitting an intermediate request for said additional information from said executing dynamic page on said server-side computer to said client and entering a wait state for said executing dynamic page until a response from said client is received;

receiving said information from said client by a notifier entity in said dynamic webcontent execution environment on said server-side computer and parsing, extracting and passing said information to said executing dynamic page; and

continuing execution of said executing dynamic page utilizing said additional information based on receiving notification from said notifier entity; and

transmitting a response to said client based upon a result of said completely executed dynamic page.

2. The method according to claim 1, wherein the receiving of said request includes receiving a request for a javaserver page (JSP), and compiling said JSP into a servlet.

3. The method according to claim 1, wherein said dynamic page comprises an Active Server Page (ASP).

4. The method according to claim 1, wherein said receiving of said request comprises forwarding said request to a container to locate said requested dynamic page.

5. The method according to claim 1, wherein said passing of said information to said executing dynamic page comprises notifying said executing dynamic page in said wait state to resume execution from the point where said executing dynamic page entered said wait state.

6. A system for executing a dynamic page comprising:

first receiving means for receiving a request from a client for execution of a dynamic page in a dynamic webcontent execution environment on said server-side computer;

processing means for processing said dynamic page in said dynamic webcontent execution environment on said server-side computer, wherein said dynamic page includes a plurality of code blocks each requiring input from said client in series and to be executed in series;

transmitting means for transmitting from said server-side computer to a client an intermediate request for additional information and entering a wait state for said executing dynamic page until a response from said client is received; and

second receiving means for receiving said additional information from said client in said dynamic webcontent execution environment on said server-side computer and parsing, extracting and passing said information to said executing dynamic page,

wherein said processing means continues execution of said dynamic page based on being notified by said second receiving means of receiving said additional information,

wherein said transmitting means is further configured to transmit a response to said client based upon the result of said processing of said dynamic page.

7. The system according to claim 6, wherein said dynamic page enters a wait state prior to said transmitting means transmitting said intermediate request.

8. The system according to claim 6, wherein said second receiving means further comprises means for passing said additional information to said processing means and means for notifying said dynamic page to resume processing utilizing said additional information.

9. The system according to claim 7, wherein said second receiving means comprises a notifier entity.

10. The system according to claim 6, wherein said processing means further comprises means for compiling a Javaserver page (JSP) into a servlet.

11. The system according to claim 6, wherein said processing means further comprises means for suspending execution of said dynamic page and entering a wait state.

12. A non-transitory computer program product comprising a computer readable medium having a computer program recorded therein for performing a method of executing a dynamic page, said method comprising:

receiving a request from a client for execution of said dynamic page in a dynamic webcontent execution environment on said server-side computer;

initiating execution of said executing dynamic page in said dynamic webcontent execution environment on said server-side computer, wherein said dynamic page includes a plurality of code blocks each requiring input from said client in series and to be executed in series;

at each instance when said executing dynamic page requires additional information for one of said plurality of code blocks from said requesting client to continue execution, then;

transmitting an intermediate request for said additional information from said executing dynamic page on said server-side computer to said client and entering a wait state for said executing dynamic page until a response from said client is received;

receiving said information from said client by a notifier servlet in said dynamic webcontent execution environment on said server-side computer and parsing, extracting and passing said information to said executing dynamic page; and

continuing execution of said executing dynamic page utilizing said additional information based on receiving notification from said notifier entity; and

transmitting a response to said client based upon a result of said completely executed dynamic page.

13. A system for executing a dynamic page comprising:

a first receiver adapted to receive at least a request from a client for said dynamic page in a dynamic webcontent execution environment on said server-side computer;

a processor adapted to process said dynamic page in said dynamic webcontent execution environment on said server-side computer, wherein said dynamic page includes a plurality of code blocks each requiring input from said client in series and to be executed in series;

a transmitter adapted to transmit an intermediate request from said server-side computer to said client for additional information for one of said plurality of code blocks to said client and enter a wait state for said executing dynamic page until a response from said client is received; and

a second receiver adapted to receive said additional information in said dynamic webcontent execution environment from said client and to parse, extract and pass said additional information to said executing dynamic page,

wherein said processor continues execution of said dynamic page based on being notified by said second receiver of receiving said additional information,

wherein said transmitter is adapted to transmit a response to said client based upon a result of said completely executed dynamic page.

14. The system according to claim 13, wherein said dynamic page is adapted to enter a wait state prior to said transmitter transmitting said intermediate request.

15. The system according to claim 13, wherein said receiver is further adapted to pass said additional information to said processing dynamic page and notify said dynamic page to resume processing utilizing said received additional information.

16. The system according to claim 13, wherein said second receiver comprises a notifier entity.

17. The system according to claim 13, wherein said processor is further adapted to compile a javaserver page (JSP) into a servlet.

18. The system according to claim 13, wherein said processor is further adapted to suspend execution of said dynamic page and enter a wait state.
