Abstract

A method of and a system for processing an enterpise an application request on an end user application and an application server. This is accomplished by initiating the application request on the end user application in a first language (such as a markup language) with a first application program (such as a Web browser), and transmitting the application request to the server and converting the application from the first language of the first end user application to a language running on the application server, processing the application request on the application server, and transmitting the response from the application server back to the end user application, and converting the response from the language running on the application server to the language of the end user application. The end user application and the application server have at least one connector between them, and the steps of (i) converting the application request from the language of the end user application (as a source language) to the language running on the application server (as a target language), and (ii) converting the response to the application request from the language running on the application server (as a source language) to the language of the end user application (as a target language), each include the steps of invoking connector metamodels of the respective source and target languages, populating the connector metamodels with metamodel data of each of the respective source and target languages, and converting the source language to the target language.

Dependent claims

A method of processing an application request on an end user application and an application server comprising the steps of:

a) initiating the application request on the end user application in a first language with a first application program;
b) transmitting the application request to the server and converting the application request from the first language of the first end user application to COBOL running on the application server;
c) processing said application request on the application server;
d) transmitting a response to the application request from the application server to the end user application, and converting theresponse to the application request from COBOL running on the application server to the first language of the first end user application;
and
e) wherein the end user application and the application server have at least one connector therebetween, and the steps of (i) converting the application request from the first language of the first end user application as a source language to the COBOL running on the application server as a target language, and (ii) converting a response to the application request from the COBOL running on the application server as a source language to the first language of the first end user application as a target language, each comprise the steps of:
1) invoking connector metamodels of respective source and COBOL target languages;
2) populating the connector metamodels with metamodel data of each of the respective source and COBOL target languages;
and
3) converting the source language to the COBOL arget language.

A transaction processing system comprising a client, a server, and at least one connector therebetween,

a) the client having an end user application, and being controlled and configured to initiate an application request with the server in a first language with a first application program and to transmit the application request to the server;
b) the connector being configured and controlled to receive the application request from the client, convert the application request from the first language of the first end user application running on the client to COBOL language running on the server;
c) the server being configured and controlled to receive the converted application request from the connector and processing the said application request in COBOL language with a second application program residing on the server, and to thereafter transmit a response to the application request through the connector back to the first application program on the client;
d) the connector being configured and controlled to receive a response to the application request from the server, to convert a response to the application request from the COBOL language running on the application server to the first language of the first application program running on the client;
and
e) wherein connector between the client and the server is configured and controlled to (i) convert the application request from the first language of the client application on the client as a source language to the COBOL language running on the application server as a target language, and (ii) convert the response to the application request from the COBOL language running on the application server as a source language to the first language of the client application running on the client as a target language, each by a method comprising the steps of:
1) retrieving connector metamodels of respective source and target languages from a metamodel metadata repository;
2) populating the connector metamodels with metamodel data from the metamodel metadata repository for each of the respective source and target languages;
and
3) invoking the retrieved, populated connector metamodels and converting the source language to the target language.

7 more elements

A transaction processing system configured and controlled to interact with a client application, and comprising a COBOL server, and at least one connector between the server and the client application, where the client has an end user application, and is controlled and configured to initiate an application request with the server in a first language with a first application program and to transmit theapplication request to the server, wherein:

a) the connector being configured and controlled to receive an application request from the client, convert the application request from the first language of the first end user application running on the client to the COBOL language running on the server;
b) the server being configured and controlled to receive the converted application request from the connector and process the said application request in the COBOL language with a second application program residing on the server, and to thereafter transmit a response to the application request through the connector back to the first application program on the client;
c) the connector being configured and controlled to receive the application request from the server, to convert a response to the application request from the COBOLlanguage running on the application server to the first language of the first application program running on the client;
and
d) wherein connector between the client and the server is configured and controlled to (i) convert the application request from the first language of the client application on the client as a source language to the COBOL anguage running on the application server as a target language, and (ii) convert the response to the application request from the COBOL language running on the application server as a source language to the first language of the client application running on the client as a target language, each by a method comprising the steps of:
1) retrieving connector metamodel metadata of respective source and target languages from a metamodel metadata repository;
2) populating the connector metamodels with metamodel data of each of the respective source and target languages from the metamodel metadata repository and invoking the retrieved, populated connector metamodels;
and
3) converting the source language to the target language.
