Tiivistelmä
The purpose of this thesis is to illustrate an enterprise project named HUVA, in which Java Platform 2, Enterprise Edition (J2EE) architecture and patterns are applied. This study took a constructive research approach: It starts from the application domain including the initial plan and business model, then moves to the system architecture covering the architecturally significant requirements and the system structure compliant with J2EE architecture, finally ends at the application design elaborated by applying the J2EE patterns at a high level. As a result the architectural and application design satisfied the project needs and requirements; and the HUVA software has been implemented in practice according to the design.
