1. 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.
