Abstract

A method and system for handling requests from a user and rendering a resulting page in HTML useful in effectuating aspects of an order management system, which reduces the redundancy in the underlying code required to effectuate the HTML page. An embodiment of the present invention modularizes various parts of an HTML page, effectuating the re-use of certain portions of code, advantageously reducing redundancy. In one embodiment, the present invention associates each HTML page with a form mapped to a servlet in a system backend. The servlet performs appropriate action based on corresponding user action. Each user action calls a set of re-usable helper class methods. Upon completion of processing, the servlet calls a render method. The active render method internally calls re-usable render methods in helper classes. These populate NTV data used by a JSP to generate a new HTML page accordingly.

Claims

populating a name value pair with corresponding data;

applying said name value pair populated with said data to a vehicle for displaying dynamic content on pages in a high order presentation language; and

drafting said second page;

wherein the method further comprises;

the server computer receiving input indicating a second user action that represents a second action to be implemented on another electronic form of the application currently executing on at least the server computer; and

in response to receiving the input indicating the second user action, a different one of the plurality of server-side processing components that is mapped to the other electronic form generating another page in a high order presentation language, wherein said generating another page comprises calling at least one of the same said helper class method and the same said render method that was called for said generating the second page such that the respective one and the different one of the plurality of server-side processing components both call the same at least one of the said helper class method and said render method for generating the second page and the other page, respectively.

2. The method as recited in claim 1, wherein said high order presentation language comprises HyperText Markup Language (HTML).

3. The method as recited in claim 1, wherein said first page, said second page, and said pages comprise HTML pages.

4. The method as recited in claim 1, wherein each of said plurality of server-side processing components comprises a servlet.

5. The method as recited in claim 1, wherein said form comprises a business form.

6. The method as recited in claim 5, wherein said business form comprises a modality for performing an electronic commerce transaction.

7. The method as recited in claim 1, wherein said vehicle for displaying dynamic content on pages in a high order presentation language comprises a Java Server Page (JSP).

8. A non-transitory, computer-readable storage medium storing program instructions computer-executable to implement a plurality of server-side processing components each configured to:

receive input indicating a user action that is performed on a first page in a high order presentation language, wherein the first page is associated with an electronic form of a currently executing application and comprises an encoding of said electronic form, wherein said electronic form is one of a plurality of electronic forms associated with respective pages, wherein each of the plurality of electronic forms is mapped to a respective one of the plurality of server-side processing components, wherein the plurality of server-side processing components process user input received for the respective electronic form, each wherein at least two of the electronic forms are mapped to different respective ones of the plurality of server-side processing components, such that user input for different electronic forms is processed by different respective ones of the server-side processing components, and wherein the user action represents an action to be implemented on the electronic form of the currently executing application that is associated with the first page;

wherein in response to said receiving, the respective one of the plurality of server-side processing components that is mapped to the electronic form that is associated with the first page is configured to;

generate a second page in a high order presentation language; and

provide the second page to a client for display;

wherein said generating the second page comprises;

calling a helper class method corresponding to the action to be implemented on the electronic form; and

calling a corresponding render method;

wherein said program instructions are further executable to implement said helper class method, and wherein said helper class method is configured to, in response to said calling the helper class method, perform the action on the electronic form; and

wherein said program instructions are further executable to implement said render method, and wherein said render class method is configured to perform, dependent on the performance, by the helper class method, of the action on the electronic form;

populating a name value pair with corresponding data;

applying said name value pair populated with said data to a vehicle for displaying dynamic content on pages in a high order presentation language; and

drafting said second page;

wherein a different one of the plurality of server-side processing components that is mapped to another electronic form of a currently executing application is configured to;

receive input indicating a second user action that represents a second action to be implemented on the other electronic form; and

in response to said receive input indicating a second user action, generate another page in a high order presentation language, wherein said generating another page comprises calling at least one of the same said helper class method and the same said render method that was called for said generating the second page such that the respective one and the different one of the plurality of server-side processing components both call the same at least one of the said helper class method and said render method for generating the second page and the other page, respectively.
