The Design And Implementation Of The Document Sharing And Conversion Server

With the progress of communication network and computer technology,network video conference technology has been widely used and developed.It interconnects users in different places through transmission lines and multimedia devices,and realizes real-time interactive communication.In such video conference system,a dual-stream module must be added,if there is a need for file sharing.With the dual-stream module,both parties may access data files such as PPT and Word on the local PC.However,data transmission is unidirectional in this way.At any time,when one end sends files,the other end can only watch them.For many customer groups,they need both sides to discuss and modify the document at the same time.The traditional data sharing method can not meet their needs.To solve these problems,this thesis integrates and optimizes multiple technology of document editing and conversion,and implements a Web application server: sharing and conversion server.Based on J2 EE architecture,this system uses Tomcat as the Web application server,uses Open Office to provide document editing service,uses JODCoverter to convert documents(PPT,Word,Excel and other Office documents),and uses ICEPdf to perform image conversion processing on PDF files.The system can convert multiple document formats,and provide document conversion services for electronic whiteboard in conferences.It can also provide services for third-party applications.This thesis discusses the overall analysis,detailed design and specific implementation of the document sharing and conversion server,and conducts a series of system testing.Test results show that the system meets the design goal.
