In this paper, we present a generic optimization of legacy codes in SOA workflows. To ease the embedding of Legacy-codes in the Service-based framework, an application independent service is required. To address the problem of exposing legacy code command-line programs as services, tool is described with the Legacy codes. This is hardly compatible with our approach, which aims at the whole application execution at run time. This embedding service highly simplifies application development because its enable to wrap any legacy code with a minimal effort. In this paper, we first discuss Service-based code invocation. We defined the benefits of the Service-based approach from a user point of view. The application-code in the Service-based framework at very little cost, allowing an easy composition of complex application as service-based workflows. Thus the idea of SOA and web service technology are also analysed in detail.
