Abstract: This paper introduces the background of Service-Oriented Architecture (SOA), WebService and component technology.Then, proposes a construction program of J2EE-based system component integration platform and generally introduces the components and technology roadmap of the platform. Finally, takes OA (Office Automation) system as a case in the application design, including the overall design program, the extraction of reusable components and the details of design, implementation and request service of the electronic form. The practice proves that construction program of the platform and component-based design schema of business system described in this paper has obvious advantages for reusing of components, further decoupling system, reducing the system complexity index, improving development efficiency and reducing development and maintenance costs.
