Using Flexpaper to achieve online preview of PDF files

Java+flexpaper+swftools Imitation Library document online reading

Reproduced from: http://my.oschina.net/stephenzou/blog/144489

I. The idea of online reading of documents
1. Convert ppt, Word, Excel, text to PDF with OpenOffice
2. Convert the generated PDF to SWF using Swftool and then use Flexplayer to achieve online preview playback
Ii. preparatory work
1. Installation OpenOffice, website download address: http://www.openoffice.org/download/index.html, the latest version of 3.4.1, I use the version of 3.3.0:http:// Pan.baidu.com/share/link?shareid=1181746637&uk=1913152192#dir/path=%2f%e8%bd%af%e4%bb%b6%e5%b7%a5%e5%85%b7
2. Start the OpenOffice service, cmd command into the OpenOffice installation directory under the program directory, type the following command
Soffice "-ACCEPT=SOCKET,HOST=LOCALHOST,PORT=8100;URP; Staroffice.servicemanager "-nologo-headless-nofirststartwizard

3. Download jodconverter:http://sourceforge.net/projects/jodconverter/files/, the project mainly uses the Lib directory of the jar package.
4. Download and install swftools:http://www.swftools.org/download.html, download EXE file installation complete
5. Download Flexplayer
http://pan.baidu.com/share/link?shareid=1181746637&uk=1913152192#dir/path=%2F%E8%BD%AF%E4%BB%B6%E5%B7%A5% E5%85%b7
Website Download Address: http://flexpaper.devaldi.com/download/, version of 2.1.5, and 1.5.1 there is a big difference, did not use the latest version.

third, software development
1. Create a new Web project and introduce a jar package
Read the DEPENDENCIES.txt in the Jodconverter/lib directory to see which jar packs you need to add

Create a new Officeonline project, introduce the corresponding jar package (using Cos for document upload, Cos.jar need to download another), will flexpaper_1.5.1_ Flash.zip after extracting the JS directory into the project, FLEXPAPERVIEWER.SWF also introduced in

2. New Docconverter.java
Note: Depending on the swftools installation path, you need to modify the Pdf2swf.exe path in the pdf2swf () method, the path I install is in D disk
The main () test modifies the test according to its own document path.
