Research and Implementation on Technologies of Constructing Network Virtual Lab

With the continue development and progress of computer and network technologies, network virtual laboratory gains more and more deployment. First of all, this paper introduces the roadmap and characters of network virtual lab. Second, we give out several key technologies that can implement network virtual lab, such as Java ,ActiveX , VRML and ASP. At the end, we discuss the implementation procedure of network virtual laboratory based on J2EE technology in deep.
