Reengineering a legacy system to provide Web Services is a great challenge. Wrapping legacy systems is a proper solution to expose legacy program functionalities as Web Services. In this paper we propose a new approach in two phases to integrate legacy programs written in legacy languages such as C or Pascal into Web Services. This will be done by analyzing the legacy program and creating a Service Bus Class. Also, an automatic wrapping tool is developed to generate Web Services and related source code in Microsoft .Net environment. To evaluate this approach a legacy student learning program was wrapped into Web Services.
