Abstract

A system and method for representing MFS control blocks in XML for MFS-based IMS applications utilizes an MFS XML adapter and an MFS XML repository to translate between XML and MFS. The repository contains XML files for DOF/MOD and XML files for DIF/MID. When an XML request is received, the XML request is transformed to a byte stream by retrieving the relevant information from the MFS XML repository. The byte stream can then be placed in an IMS message queue to await processing by an MFS-based IMS application program. A byte stream response is generated by the MFS-based IMS application and is transformed into an XML response, again, by retrieving the relevant information from the MFS XML repository.

Claims

1. A method for representing MFS control blocks in XML for MFS-based IMS applications, comprising the acts of:

establishing an MFS XML repository having at least one XML file representing at least one MFS control block; and

at least partially based on the XML file, transforming an XML request into a byte stream request.

2. The method of claim 1, further comprising the act of:

processing the byte stream request with an MFS-based IMS application program to yield a byte stream response.

3. The method of claim 2, further comprising the act of:

at least partially based on the XML file, transforming the byte stream response into an XML response.

4. The method of claim 3, further comprising the act of:

parsing a first MFS source file; and

determining whether an unresolved external reference is encountered while parsing the first MFS source file.

5-8. -8. (canceled)

9. A system for representing MFS control blocks in XML for MFS-based IMS applications, comprising:

an MFS XML adapter;

an MFS XML repository connected to the MFS XML adapter, the MFS XML repository including at least one XML file representing at least one MFS control block; and

a computer program for representing MFS control blocks in XML for MFS-based IMS applications, the computer program comprising;

logic means for transforming an XML request into a byte stream request at least partially based on the MFS control block within the MFS XML repository.

10. The system of claim 9, wherein the XML file is at least one of the following:

an XML file for device output format/message output descriptors (DOF/MOD) and an XML file for device input format/message input descriptors (DIF/MID).

11. The system of claim 10, wherein the computer program further comprises:

logic means for processing the byte stream request with an MFS-based IMS application program to yield a byte stream response.

12. The system of claim 11, wherein the computer program further comprises:

logic means for transforming the byte stream response into an XML response at least partially based on the files in the MFS XML repository.

13. The system of claim 12, wherein the computer program further comprises:

logic means for parsing an first MFS source file; and

logic means for determining whether an unresolved external reference is encountered while parsing the first MFS source file.

16. The system of claim 13, wherein the computer program further comprises:

logic means for parsing a second MFS source file; and

logic means for determining whether a previously encountered externally referenced control block is again encountered while parsing the second MFS source file.

14-15. -15. (canceled)

17. (canceled)

18. A computer program device for representing MFS control blocks in XML for MFS-based IMS applications, comprising:

logic means for receiving an XML request;

logic means for transforming the XML request into a byte stream; and

logic means for placing the byte stream request in an IMS message queue.

19. The computer program device of claim 18, wherein the XML request is transformed into a byte stream at least partially based on one or more files stored in an MFS XML repository.

20. The computer program device of claim 19, further comprising:

logic means for receiving a byte stream response from the IMS message queue; and

logic means for transforming the byte stream response into an XML response at least partially based on one or more files stored in the MFS XML repository.

21-22. -22. (canceled)

23. A computer program device for representing MFS control blocks in XML for MFS-based IMS applications, comprising:

logic means for establishing an MFS XML repository having at least one XML file representing at least one MFS control block; and

logic means for transforming an XML request into a byte stream request at least partially based on the XML file.

24. The computer program device of claim 23, further comprising:

logic means for parsing a first MFS source file; and

logic means for determining whether an unresolved external reference is encountered while parsing the first MFS source file.

25-28. -28. (canceled)
