This article primary state the needs, design, exploitation and achievement of the examsystem online of J2EE. At the same time, the feature of the system has also been explained in the article.The author, me, has some years'teaching experience, especially has done researchment in the segment of examination. On the basis of research on the similar software product both at home and abroad, I think exploiting an examsystem of multidimensional analysis is a meaningful project. The similar product both at home and abroad pay more attention on commercial value, they provide much function, but these function doesn't especially concern on the final purpose of examination, which is how to enhance teaching quality, how to find both teachers and students'weakness through examination, thus the education and teaching can have entirety improvement.The examsystem online of J2EE which is exploited by me let it come true, it reveals the essence meaning of examination more profound.The system let paperless examination come true, it supports the idea of green environmental protection The system not only provides basic function of managing test paper, test questions and students'information, but also provides networking support to all the examination procedure. The feature of the system is analysis module of examination result. This module provides analysis from much dimension, like class, test paper, test question and multi-class. The intelligence analysis objectively and directly opens up to users with data and figure. So users can easily dig the problems in teaching and education, find students'weakness in their study. All of these can provide support and reference to teaching and education. In addition, from the multi-class errorrate comparison, the teachers who teach the same course can communicate,share and improve teaching experience specific and nichetargeting.After the exploitation of the system, I have used this system to organize examination to students, the results prove that the system can not only improve examination efficiency, but also alleviate teachers'burden, at the same time, the system can alleviate mistakes in scoring segment, thus the examination results can be more accurate.
