Access to Legacy Applications and Data

Step 3: Writing the Application

1. Write the client in a language that supports referencing of Automation objects, such as Visual Basic, Visual C++, or Visual J++.
2. Add the appropriate COMTI component library to the references list in the project and add the references of the component in the program.
3. Invoke methods as appropriate throughout the application.
4. Define any transaction-related attributes in the COMTI component. These attributes will handle transactions in a manner transparent to the client application (for example, an IIS 5.0 application using ASP). The COMTI component will call both the Component Services/Distributed Transaction Coordinator  (DTC) and the transaction processing program running on CICS.
