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 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;

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;

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), and 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;

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

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.

2. The system of claim 1, 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.

3. 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;

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

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.
