Abstract

A method includes receiving a message in a JavaScript object notation (JSON) format from a first processor, converting the message from the JSON format into a hypertext markup language (HTML) format, and presenting the content of the message in the HTML format to a user on a display.

Claims

1. A method including:

receiving a message in a JavaScript object notation (JSON) format from a first processor;

converting the message from the JSON format into a hypertext markup language (HTML) format; and

presenting the content of the message in the HTML format to a user on a display.

2. The method of claim 1, wherein the converting the message from the JSON format into the HTML format includes:

identifying a key word of the message in the JSON format;

creating an HTML element associated with the key word; and

filling the HTML element with corresponding data from the JSON format.

3. The method of claim 1, wherein the message includes a screen ID.

4. The method of claim 3, wherein the method includes:

determining whether the screen ID of the message matches a screen ID associated with a first portion of the display; and

presenting the content of the message in the HTML format in the first portion of the display responsive to determining that the screen ID of the message matches a screen ID associated with a first portion of the display to the user.

5. The method of claim 3, wherein the method includes:

determining whether the screen ID of the message matches a screen ID associated with a portion of the display; and

generating a new portion of the display responsive to determining that the screen ID of the message does not match a screen ID associated with a first portion of the display;

presenting the content of the message in the HTML format in the new portion of the display to the user.

6. The method of claim 1, wherein the converting the message from JSON format into HTML format is performed by a web client application on a second processor.

7. The method of claim 1, wherein the first processor is a mainframe processor.

8. The method of claim 1, wherein the message is received from a servlet application.

9. The method of claim 1, wherein the message is sent from a time sharing option (TSO) address space of the first processor.

10. The method of claim 1, wherein the message is sent from an interactive system productivity facility (ISPF) session.

11. An article of manufacture tangibly embodying computer readable instructions which, when implemented, cause a computer to carry out the steps of a method according to claim 1.

12. A system including:

a display; and

a first processor communicatively connected to the display, the first processor operative to receive a message in a JavaScript object notation (JSON) format from a second processor, convert the message from the JSON format into a hypertext markup language (HTML) format, and present the content of the message in the HTML format to a user on the display.

13. The system of claim 12, wherein the converting the message from the JSON format into the HTML format includes:

identifying a key word of the message in the JSON format;

creating an HTML element associated with the key word; and

filling the HTML element with corresponding data from the JSON format.

14. The system of claim 12, wherein the message includes a screen ID.

15. The system of claim 12, wherein the first processor is operative to determine whether the screen ID of the message matches a screen ID associated with a first portion of the display;

and present the content of the message in the HTML format in the first portion of the display responsive to determining that the screen ID of the message matches a screen ID associated with a first portion of the display to the user.

16. The system of claim 12, wherein the first processor is operative to determine whether the screen ID of the message matches a screen ID associated with a portion of the display, and generate a new portion of the display responsive to determining that the screen ID of the message does not match a screen ID associated with a first portion of the display, present the content of the message in the HTML format in the new portion of the display to the user.

17. The system of claim 12, wherein the converting the message from JSON format into HTML format is performed by a web client application on the first processor.

18. The system of claim 12, wherein the second processor is a mainframe processor.

19. The system of claim 12, wherein the message is received from a servlet application.

20. The system of claim 12, wherein the message is sent from a time sharing option (TSO) address space of the first processor.

21. The system of claim 12, wherein the message is sent from an interactive system productivity facility (ISPF) session.

22. A method including:

receiving an input from a user on a first processor;

converting the input from a hypertext markup language (HTML) format to a JavaScript object notation (JSON) format message; and

sending the JSON message to a second processor.

23. The method of claim 22, wherein the converting the input from the HTML format into the JSON format includes:

adding a screen identifier and panel name to the JSON message;

identifying a type of HTML response in the input;

creating a JSON element associated with the type of HTML response; and

filling the JSON element with corresponding data from the input.

24. An article of manufacture tangibly embodying computer readable instructions which, when implemented, cause a computer to carry out the steps of a method according to claim 22.

25. A system including:

a display; and

a first processor communicatively connected to the display, the first processor operative to receive an input from a user on a first processor, convert the input from a hypertext markup language (HTML) format to a JavaScript object notation (JSON) format message, and send the JSON message to a second processor.
