Method and system for converting user interface source code of a legacy application to web pages

A computer readable medium containing program instructions for creating web interfaces of an application stored on a computer, said program instructions for:

• (a) parsing display file data description source of the application to render the source into a plurality of network user interface pages, each network user interface page to display a record format of the application;
• (b) converting the network user interface page, wherein at least one data object maintains the application's input, output, feedback data on a client and at least one web-browser page maintains the application's static content;
• (c) dynamically updating the web-browser page with the application's input, output, feedback data via a servlet instance;
• and
• (d) displaying the web-browser page on a client via a network.

A computer readable medium containing program instructions for use in a computer network, said computer readable medium containing program instructions for:

• (a) providing a plurality of network user interface pages of format records of display source code of a application;
• the network user interface pages to receive data from the application and in response thereto;
• and
• (b) converting the network user interface pages to web-browser pages, a static portion of which displays the static portion of the format record and a dynamic portion of which interacts with the web-browser page to display input, output, feedback data required by/from/of the application.

A computer system for executing an application, comprising:

• a central processing unit;
• a main memory connected to the central processing unit with a communication bus;
• a data storage unit connected to a data storage interface which is connected to said communication bus;
• at least one input/output device connected to said communication bus and connected to a network interface to an external computer network,
• an application stored in said main memory and capable of executing on said central processing unit;
• and
• a plurality of intermediate network user interface pages, each of which correspond to a record format of the application;
• wherein as the application executes, the application logic may use either a traditional display of the record format or the plurality of intermediate network user interfaces pages for communication of the application to a user over the external computer network.

A computer server for converting the display source of an application stored and executing on a computer, comprising:

• a central processing unit;
• a parser to parse the display source into a plurality of record formats;
• each of the record formats unique to each input/output screen definition of the application;
• a generator of web-language user interface files having nested tags of each of the record formats;
• and
• a converter of web-language user interface files, the converter further comprising:
• an object creator to create dynamic components for the dynamic portions of the display source;
• and
• a static component for display of the unchanging aspects of the record formats.
