J2EE-based Online Video Retrieving System Design and Implementation

Abstract

Most video contents on the Internet are regularly watched online, but it is also necessary for users to download them to local storage for further processing. Currently, many online video websites provide their own service for website specific video retrieving; it is difficult to build an integrated web retrieving system adapted for all online video website due to different protocols. This paper presents an online video address discovery and retrieving system which supports multiple online video protocols and formats, parallel retrieving task scheduling; vast amounts of unstructured data and video file storage management, it is suitable for integration in high load, large scale enterprise applications to provide video retrieving service.

A Java EE Platform Test System Based on Improved Genetic Algorithm

“…Online network test alternative to traditional exams throughout the examination process must be implemented to achieve the questions of digital management, improving the volume efficiency, maneuverability and interactivity can automatically and effectively save data graders, automatically generate transcripts, test scores can provide statistics analysis functions. Therefore, the development of online examination system to adapt to the new situation is necessary [4][5].…”
