The purpose of this research is based on JavaEE technology architecture of application systems, the use of artificial intelligence and reasoning mechanism of consultations, to establish a complete knowledge of learning model, the application of self-adaptive and learning to self-expansion, to adapt to changing and expanding application needs. The research project will be applied to Web-based application system, it has in consultation with users and improve self-learning knowledge base and database capabilities to better meet the increasingly complex enterprise application requirements. The main technique is the use of JavaEE technology and Agent System technology in the consultation mechanism, the use of appropriate development platform to study the adaptive learning model of knowledge in the application in consultation mechanism.
