目前国内基于B/S、C/S结构的在线考试系统产品已经有许多，本文首先介绍了这些考试系统的形成和发展过程，大致结构。然后通过仔细分析，提出了目前的这些系统还存有系统更新和维护等种种弊端,仍不够成熟。基于对现有产品的思考，结合J2EE的成熟技术,我们想到了是否可以将该技术运用在在线考试系统中,提出了一个基于J2EE架构的在线考试系统。通过将该架构与已有结构的在线考试系统进行比较，分析了该架构的优势,重点介绍了该框架的整体构造以及相关的概念和技术。并通过设计了一个基于J2EE架构的在线考试系统对该架构做了一个比较深入的剖析。最后，对J2EE技术做了一个总结性的展望，认为该技术有着良好的发展空间和广阔的前景。

Abstract

At present, there are many b/s, c/s structure examination systems based on-line, this paper first introduced most of these systems’ formed and developed process, and structures. Then, analysis these systems, and pointed out that there still have many defects about them, just like the update and the service to these systems .Thinking based on these produces, and now the J2EE technical is becoming mature, we thinking about is this technical can be used in examination systems, so we mentioned a on-line system based on J2EE structure. Compared to other systems, and also analysis its’ advantages, we introduced this structure’s construction and technical as emphasize. Finally, make J2EE technical a expectation and it can progress quiet great and have a nice foreground.
