J2ee-based Mobile Learning System

"M_Learning" means mobile devices based on the implementation of distance-learning course, M_Learning mode of distance education has brought to the people free to the learning resource sharing era, M_Learning mode of distance education is to provide real users anywhere, anytime, personalized learning, open learning. Mobile Learning is a complete education system, which includes content from the Organization of learning materials production ,distribution, teaching ,educational management organizations, mobile devices Based on remote interactive exchanges, and Learning the information services, to software support from the area includes Teaching mobile platform, software tools, mobile interactive software, information services platform, to the technical areas including SMS, MMS, WAP, moving images, video streaming telephone, mobile Internet, PDA software development environment.For mobile learning, there are different means of technology to meet user demand for mobile learning, but because mobile devices (such as PDA, smart phones, etc.) generally do not have powerful functions and real-time processing speed is less than the requirements of the Mobile Learning. So we need a kind of solutions which can not only reduce the pressure of real-time processing, but also will satisfy users who want to use mobile learning.How to integrate the components function which has been used for a long time with the wireless function such as Wap service in hie enterprises and units , which have dependent on the use of multi-layered enterprise Java applications, the solution we call " WAP mobile learning platform and information Integrated system" which based on J2EE framework is an ideal solution.Therefore, this article introduces the J2EE construction and provides one kind of effective solution using WML and the data extract technology for the mobile study and the different database's data integration. After introducing mobile study and technical related standard, this paper focus on dynamic interaction using WML and the data integration. The project which the paper mentioned has already been in used in GTVU for testing.
