Java simulation Implementation of Baidu document online browsing

Java simulation Implementation of Baidu document online browsing

This idea is my reference to the Internet, code is my implementation.

Use the OpenOffice below Apache to convert the resource file into a PDF file, then convert the PDF file into a SWF file and browse with Flexpaper.

Ok

A, download OpenOffice (convert resource file)

B. Download Jodconverter (call OpenOffice)

C, download swftools (pdf2swf)

D. Download flexpaper (browse swf file)

Here I have all downloaded, all you need to download: http://down.51cto.com/data/1980603

After the download, do not hurry to install, please read this blog post

1, first look at our MYECLIPSE engineering structure

5, modify the index.jsp

<%@ page language= "java"  import= "java.util.*" pageencoding= "UTF-8"%><! Doctype html public "-//w3c//dtd html 4.01 transitional//en" >

6. Writing basefile.jsp files

<%@ page language= "java"  contenttype= "Text/html; charset=utf-8"      pageencoding= "UTF-8"%><! doctype html public  "-//w3c//dtd html 4.01 transitional//en"   "HTTP// Www.w3.org/TR/html4/loose.dtd ">

Note The code in the basefile.jsp, not you can refer to here

7, to be completed here, it is important to note that:
1, 650) this.width=650; "src=" Http://s3.51cto.com/wyfs02/M01/59/4C/wKioL1TPPbDCQ7SOAAAj1OEioRA406.jpg "title=" 6. JPG "alt=" wkiol1tppbdcq7soaaaj1oeiora406.jpg "/> file installation path not too deep, lest Java Call external command, cannot execute, I here is C under the plate

2.1, Red 1 mark the path can not be wrong, I made this mistake
2.2, Red Flag 2 can also write http://127.0.0.1:8080/baiduDoc/reader/...

3, start the OpenOffice command, not directly double-click to start.
After installing OpenOffice
1. Installation Services
CD C:\Program Files (x86) \openoffice4\program
This step you can see where your OpenOffice is installed
Perform
Soffice-headless-accept= "SOCKET,HOST=127.0.0.1,PORT=8100;URP;"-nofirststartwizard
2. See if the installation was successful
2.1 Viewing the PID of the port
Netstat-ano|findstr "8100"
2.2 View the PID corresponding service program name
Tasklist|findstr "IPD Value"
