Java simulates the online browsing of Baidu documents

The idea is that I come from the Internet and the code is my implementation.
Use OpenOffice under Apache to convert the resource file into a PDF file, convert the PDF file into a swf file, and use FlexPaper to browse.
OK,
A. Download OpenOffice (convert resource files)
B. Download JodConverter (call OpenOffice)
C. Download Swftools (ipv2swf)
D. Download FlexPaper (Browse swf files)


Here I have downloaded all, you only need to download: http://download.csdn.net/detail/u010506940/8418553


After the download, do not worry about installation. Please read this blog post.

1. First look at our MyEclipse project structure

2. decompress the downloaded package and copy all jar files to the lib of baiduDoc.

3. Create a folder under WebRoot and copy all the decompressed files to FlexPaper.


4. Create a BaiDuServlet. java File

5. Modify index. jsp

<% @ Page language = "java" import = "java. util. *" pageEncoding = "UTF-8" %> <! Doctype html public "-// W3C // dtd html 4.01 Transitional // EN"> 


6. Compile the baseFile. jsp file

<% @ 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"> 


Pay attention to the Code in baseFile. jsp.

7. Notes
1. The installation path of this file should not be too deep, so that Java can call external commands and cannot execute them. Here I am the 2 SWF folder under drive C.




2,
2.1. the path marked in red 1 cannot be wrong. I made this mistake.
2.2 red mark 2 can also write http: // 127.0.0.1: 8080/baiduDoc/reader /...

3. The command to start OpenOffice is not directly started by double-clicking. The official website can be started as follows:

After the openoffice is installed, go to the command interface> cd to enter the installation directory, as shown below:
1. Install the service
Cd C: \ Program Files (x86) \ OpenOffice4 \ program
In this step, you can see where your OpenOffice is installed
Run
Soffice-headless-accept = "socket, host = 127.0.0.1, port = 8100; urp;"-nofirststartwizard
2. Check whether the installation is successful.
2.1 view the pid corresponding to the port
Netstat-ano | findstr" 8100"
2.2 view the service program name corresponding to the pid
Tasklist | findstr "ipd value"
