Java平臺要實現類似豆丁百度文科的文檔在線閱讀，總體思路是講doc docx等文件格式利用openoffice轉換成pdf再用swftools轉為swf。再用flexpaper組件顯示swf。

此過程涉及軟件(實測)

openoffice3.2(window)

swftools-2011-01-23-1815.exe(window)

openoffice3.1.1(linux)

swftools-2011-01-23-1815.tar.gz(linux)

jar包jodconverter-2.2.2(里面lib目錄下含多個要用到的jar文件)

flexpaper1.4.0 (直接復制過來,項目上運行成功,本地運行還沒成功)

FlexPaper_1.4.5_flash(網上下載的最新版本沒試過,二選一即可)

附上自己寫的java轉換Demo DocConverter.java

importjava.io.BufferedInputStream;

importjava.io.File;

importjava.io.IOException;

importjava.io.InputStream;

以上即是所有用到的轉換需要用到的文件

?

windows安裝過程省略,linux下安裝swftools命令

解壓到目錄后

./configure

make

make install

?

無論在哪個平臺安裝完以上兩個軟件后

需要在將openoffice以服務方式啟動

Window 啟動方式

cd C:\ProgramFiles\OpenOffice.org 3\program
soffice -headless -accept="socket,host=127.0.0.1,port=8100;urp;"–nofirststartwizard

Linux啟動

soffice-headless -accept="socket,host=127.0.0.1,port=8100;urp;"-nofirststartwizard &

?

?

以上是實現兩個平臺下的轉換,但是會有openoffice解析不了的字體亂碼問題,或者顯示字體變形等

更高級的web文檔應用可以參考QQ郵件,郵件實現了在線預覽excel doc pdf等格式文件并可以用鼠標點擊選取復制,期待高手解決.
