Providing a modular gateway architecture which isolates attributes of the client and server systems into independent components
First Claim
1. A data Processing system wherein a number of requesters are coupled to a server and a number of communications programs are coupled to an end server, the end server processing a number of service requests from the number of requesters and returning a number of results in response to the number of service requests, comprising:
- a. an interface coupled to the server for linking each one of the number of requesters with each one of the number of communications programs so that each one of the number of requesters can submit at least one of the number of service requests through each one of the communications programs and receive at least one of the number of results in response to said at least one of the number of service requests b. a number of first modules wherein each one of said number of first modules corresponds to one of the number of requesters; and
c. a number of second modules wherein each one of said number of second modules corresponds to one of the number of communications programs, each said one of said number of first modules able to interface with every said one of said number of second modules by passing a number of function calls between each said one of said number of first modules and every said one of said number of second modules so that each one of the number of requesters can submit at least one of the number of service requests through each one of the number of communications programs and receive at least one of the number of results in response to said at least one of the number of service requests.

Abstract
Method and apparatus for a new interface architecture which reduces the number of software components required to interface a variety of requester types coupled to a server with a variety of communications programs coupled to an on-line transaction processing system. The new interface architecture isolate attributes of the requesters and the communication programs into individual software components so that all software code associated with each requester type is included within a corresponding requester software module, and all software code associated with each communications program is included within a corresponding communications software module. Each new requester type added requires the addition of only one requester software module, and each new communications program added requires the addition of only one communications software module, thus reducing the overall number of software modules required to interface the variety of requester types to the variety of communications programs.

1. A data Processing system wherein a number of requesters are coupled to a server and a number of communications programs are coupled to an end server, the end server processing a number of service requests from the number of requesters and returning a number of results in response to the number of service requests, comprising:
-
a. an interface coupled to the server for linking each one of the number of requesters with each one of the number of communications programs so that each one of the number of requesters can submit at least one of the number of service requests through each one of the communications programs and receive at least one of the number of results in response to said at least one of the number of service requests b. a number of first modules wherein each one of said number of first modules corresponds to one of the number of requesters; and
c. a number of second modules wherein each one of said number of second modules corresponds to one of the number of communications programs, each said one of said number of first modules able to interface with every said one of said number of second modules by passing a number of function calls between each said one of said number of first modules and every said one of said number of second modules so that each one of the number of requesters can submit at least one of the number of service requests through each one of the number of communications programs and receive at least one of the number of results in response to said at least one of the number of service requests. - View Dependent Claims (2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12, 13, 14, 15, 16, 17, 18, 19, 20, 21)

22. A data Processing system wherein a number of requesters are coupled to a server and a number of communications programs are coupled to an end server, the end server processing a number of service requests from the number of requesters and returning a number of results in response to the number of service requests, comprising:
-
a. first module means coupled to the server; and
b. second module means coupled to the number of communications programs, said first module means completing a number of function calls so that said first module means can communicate a one of the number of service requests received from a one of the number of requesters to the second module means and return a one of the number of results received from the second module means to said one of the number of requesters and said second module means can communicate said one of the number of service requests to a one of the number of communications programs and return the result received from said one of the number of communication programs to said first module means. - View Dependent Claims (23, 24, 25, 26, 27, 28, 29, 30, 31, 32, 33, 34)

35. A method of communicating a request from a requester to an end server wherein the requester is coupled to a server and a number of communications programs are coupled to an end server, a first module being coupled to the server and each one of a number of second modules being coupled to a corresponding one of the number of communications programs, the end server processing the request and returning a result in response to the request, comprising the steps of:
-
a. calling a first initialize function to initialize the first module and load a one of the number of second modules corresponding to a one of the number of communications programs to communicate with the end server;
b. calling a second initialize function to initialize the one of the number of second modules;
c. sending a request from the requester to the first module;
d. calling a first process request function from the first module to format the request received from the requester so that the request can be sent to said one of the number of second modules;
e. calling a second process request function from said first process request function to send the request to said one of the number of second modules, said second process request function formatting the request received from said first module so that said one of the number of second modules can send the request to said one of the number of communication programs;
f. sending the request to said one of the number of communication programs so that the end server can process the request;
g. processing the request;
h. returning the result in response to the request from the end server to said one of the number of communication programs so that said one of the number of second modules can receive the result;
i. sending the result from said one of the number of communication programs to said one of the number of second modules;
j. formatting the result by said second process request function so that the result can be returned to the first module;
k. sensing the result from said one of the number of second modules to the first module;
l. formatting the result by said first process request function so that the result can be returned to the requester;
m. sending the result from the first module to the requester;
n. calling a first cleanup function once the requester has been removed, said first cleanup function terminating the first module; and
o. calling a second cleanup function from the first cleanup function, said second cleanup function terminating said one of the number of second modules. - View Dependent Claims (36, 37, 38, 39, 40, 41)
