Future pervasive environments will integrate the environment with enterprise systems, including software, hardware, databases, standards, and life cycle systems. Designing and implementing "enterprise-strength" pervasive applications today is a challenging task, but enterprise application has practical usage by supporting numerous clients and enterprise technology basically supports web as an application layer like JSP pages. Through web, every client can access the same application regardless of the devices such as mobile device (PDA). In line with this concept we suggest a scenario which can be occurred in usual life assuming that this system is practically used in hospital domain. We implement healthcare application which is based on J2EE platform and using Web standard technology. By using J2EE platform and XML, we can support mobility, scalability and integrity.
