A student monitoring system which can be easily accessed by parent, is important in order to reduce student violations in school. In this final project, a monitoring system is developed in SMAN 2 Sidoarjo that can provide several information for parent about attendance, payment, score, schedules, violation list, and school activities. This system can be accessed by them trough internet, using mobile devices with Java technology or using web. To simplify the process of data exchange between server and client, this monitoring system is using XML Web Service. Client application (mobile and web) cannot access directly to the database, but by calling methods that provided by the XML Web Service. Using this student monitoring system, parent can quickly find out if their children's are doing violations in school. So they can control and guiding their children's not to do that again. Key words : XML, Web Service, J2M
