------ Solution ---------------------------------- ----------
not so simple , it is best to have a background batch upload PDF documents are unified into a format or directly open the front desk to preview the PDF.
conversion process suggested tools , not limited to the Java implementation ; their use be resolved like POI achieve efficiency is too low.

1. user uploaded word, xls, ppt, pdf after such original documents processed in the background , if not pdf format are converted into pdf format with openoffice
2. obtained in the first step of pdf files can be converted by this tool into the corresponding pdf2swf.exe swf
3. step used in jsp flexpaper generated can preview the swf
OK
------ Solution ----------------------------------- ---------
our items are third-party tools to pay

------ Solution ------ --------------------------------------
not so much trouble now , java can be achieved ah. Oh, I've done :
window.onload = function() {
document.getElementById("divwrapped").innerHTML = "<iframe width='100%' height='100%' src='ajax_pageload.action?path=" + encodeURIComponent(filepath) + "' />"; };
Then in the background : ( write only the key code oh )
response.setHeader("Content-type","application/vnd.openxmlformats-officedocument.wordprocessingml.document");
// 设置下载头信息
try {
TransmitFile.downLoad(response, strUrl);
response.flushBuffer();
} catch (Exception e) {
e.printStackTrace();
}
out.flush();
out.close();
/**
* 下载文件
* @param config
* @param response
* @param downLoadFileName
*/
public static void downLoad(HttpServletResponse response,String filePath){
BufferedInputStream bis=null;
BufferedOutputStream bos=null;
try{
String filename=filePath.substring(filePath.lastIndexOf("/") + 1, filePath.length());
response.setContentType("application/x-msdownload");
response.setHeader("Content-Disposition","filename="+new String(filename.getBytes("gb2312"),"iso8859-1"));
bis =new BufferedInputStream(new FileInputStream(filePath));
bos=new BufferedOutputStream(response.getOutputStream());
byte[] buff = new byte[2048];
int bytesread;
while(-1 != (bytesread = bis.read(buff, 0, buff.length))) {
bos.write(buff,0,bytesread);
}
}catch(Exception e){
e.printStackTrace();
}finally {
if (bis != null)
try {
bis.close();
} catch (IOException e) {
e.printStackTrace();
}
if (bos != null)
try {
bos.close();
} catch (IOException e) {
e.printStackTrace();
}
}
}

flexpaper this plugin, I personally think it is very easy to use , have used before .
------ Solution ---------------------------------------- ----
determine if the type of office documents
1. Through openoffice convert files to pdf
2. speaking through swftools convert pdf files into swf format
3. browse through flex web
------ Solution ------------------------------------ --------
top 1L, my suggestion is that if the requirements are not particularly stringent , uniform turn into a pdf document , the front page with adobe reader plug-in to the online preview pdf documents, such as we have just done demand
