An extensive work has been done, across a number of fields, in modeling organizational processes. A tension has existed between the attempts to provide a rich expression of organizational activities and the desire to support the work as it actually takes places. A static business process is characterized by stable network connections, use of powerful computing devices, and an easy access to various knowledge sources within the corporate Intranet. In modeling a business process into a component, a major challenge is whether the mechanism of component combination at the code-level is readily available. Currently there is little experience concerning the modeling of relationships between components and their communication for business processes. It is considered that the connector should take charge of interactions between the software components and the associated information about the component composition, role and specification. This paper proposes business process composition method for development of web applications. Specifically we focus on the interactions of the connectors that are the interfaces between the business processes in web component. We describe the method and demonstrate that this algorithm is able to process components and interfaces. We then show the viability of this method by implementing a simple stock trading system.
