With the continuous development of computer and network technology, the degree of informationization of society is getting higher and higher, and information technology is gradually infiltrating into various fields. Network teaching can use computer to access computer information resources all over the world, and can realize teachers and networks through the network. Students conduct more extensive exchanges. This paper studies and discusses the construction process of a network teaching

... m based on J2EE technology. The E-learning system based on J2EE architecture is aimed at the problems existing in traditional teaching. Combined with the mainstream mode of network teaching, it adopts the more mature network technology, discusses the requirements and functional characteristics of the system in detail, and finally proposes a new network. Teaching system solutions. E-learning Feature E-Learning was first proposed in North America in 1990, and its basic content is based on network technology and information technology to support learning activities. The definition of E-Learning refers to the learning and teaching activities through the Internet or other digital content. It makes full use of the learning environment provided by modern information technology with new communication mechanism and rich resources to realize a new learning style: The learning style will change the role of teachers in traditional teaching and the relationship between teachers and students, thus fundamentally changing the structure of teaching and the nature of education. (1) Asynchronous communication, including online discussion forums and emails within the course. Through asynchronous communication tools, students and teachers can communicate without having to meet or at the same time[1]. (2) Synchronous communication, including text-based live chat and online audiovisual conferences. To communicate synchronously, students and teachers must log in to the same location on the web to communicate in a virtual face-to-face mode. (3) File sharing. This feature enables students and students, as well as students and teachers, to share information and collaborate on the Internet. For example, students can submit assignments directly to the teacher through file sharing, and the teacher can easily return the corrected assignments to the students[2] . (4) Working group, which is particularly suitable for group project research. Workgroup functions include group sites, group discussion areas, and group file sharing areas. If students need to do group project research, they can pass their work to a specific file-sharing area on the course website so that each member of the group can easily see the work of other members. (5) Electronic whiteboard. This tool is especially popular in math and natural science courses because students and teachers can simultaneously view a mathematical formula or other graphic on the screen, and can add and modify it at the same time. Students can save the pictures on the electronic whiteboard for future reference. The Development of J2EE J2EE (Java Platform Enterprise Edition) is a new concept model introduced by Sun Microsystems of the United States, which has incomparable advantages compared with the traditional Internet 8th International Conference on Management, Education and Information (MEICI 2018)
