Learn Java Simulation implementation Baidu document online browsing _java

This idea is I refer to the Internet and come, the code is my realization.
Use the OpenOffice below Apache to convert the resource file into a PDF file, and 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)

After downloading, do not rush to install, please read this blog post

1, first look at our MYECLIPSE engineering structure

2, will we download the Jodconverter-2.2.2.zip after decompression will all the jar files copied to the Baidudoc under the Lib to

3, under the Webroot New Flexpaper folder, will be extracted after the Flexpaper all copied to the Flexpaper

4. New 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, the preparation of basefile.jsp documents

<%@ 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" >  

Notice the code in the basefile.jsp, no you can refer here

/**************************************************************************************/

7, to be completed here, it is necessary to note that:
(1), Swftools-2013-04-09-1007.exe file installation path not too deep, otherwise Java invoke External command can not be executed

(2),

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

(3), start OpenOffice command, not directly double-click to start. The official website launches the way, uses the CD command to open installs the directory!
After installing OpenOffice
A. 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
B. See if the installation was successful
2.1 View the port corresponding to the PID
Netstat-ano|findstr "8100"
2.2 View the PID corresponding service program name
Tasklist|findstr "IPD Value"
