The key steps that we need to develop for our sample application are to:
Implement a server object that represents a customer account, as defined in IDL. This account object must provide methods to allow clients to request account data by account number.
Wrapper the COBOL (NACT02) program as a Java program. The JCICS classes are used to link to the COBOL program, request account data.
Set the account fields, returned by the COBOL program, in the account object and return to the client.
The overall solution is illustrated in Figure 6-3.
