Recently, when developing a XX System for the customer, the customer requested to upload the documents (including *. doc ;*. docx ;*. XLS ;*. XLSX ;*. PPT ;*. pptx ;*. pdf;) can only be previewed, cannot be downloaded, cannot be printed.
I just wanted to go to Baidu Library and douding network. The Online previews of Baidu Library and douding network both use flash to play documents. I checked a lot of materials online and finally realized this function,
Now you can download your own design and implementation as follows.
How can I convert a file to a SWF file supported by flash for online playback?
1. Use OpenOffice*. Doc; *. docx; *. xls; *. XLSX; *. ppt; *. pptx; *. PDFConvert a document type to a PDF file
2. Use swftools to Convert PDF to SwF, and then use the flexpaper plug-in to implement online playback preview.
OpenOffice
OpenOffice.org is a cross-platform office software suite that can be executed on Windows, Linux, MacOS X (X11), Solaris, and other operating systems. It is compatible with major office software kits. OpenOffice.org is a free software that anyone can download, use, and promote for free.
Main modules include writer, impress, Calc, draw, math, and base)
The latest Chinese official version: Apache_OpenOffice_incubating_3.4.1_Win_x86_install_zh-CN.
Flexpaper
Flexpaper is an open-source lightweight component used to display various documents in a browser. It is designed to be used with ipv2swf to display PDF in flex, this process does not require the support of the PDF software environment. It can be used as a flex library. In addition, you can convert documents such as Word and PPT into PDF files for online browsing.
Every time you start this command, you can write a BAT file.
Log on to the Windows Task Manager and check that there is a process named soffice. bin. This indicates that OpenOffice is started successfully!
(3) install swftools (install to c: \ Program Files). swftools converts PDF files to SWF files for flexpaper playback. : Http://www.swftools.org/download.html
(4) download flexpaper: http://flexpaper.devaldi.com/download/
(5) download the OpenDocument converter jodconverter. jodconverter is a Java openducument file converter that can convert many file formats. It uses OpenOffice for conversion, it can perform the following conversions:
A. convert Microsoft Office to openducument and openducument to Microsoft Office
B. Convert openducument to PDF, convert Word, Excel, PowerPoint to PDF, and convert RTF to PDF.

Sample Code:
1. copy the file to the root directory of the website (this file is mainly used in the player that plays the SWF file on the webpage). The directory structure is as follows:
2. Create an onlineread. jsp file
