下载文档主附件文件

如何用后台程序将wtdocument的物理文件和附件下载下来

WTDocument doc = (WTDocument) queryresult.nextElement();
    wt.content.ContentHolder ch = wt.content.ContentHelper.service
      .getContents(doc);
    Vector attachmentList = wt.content.ContentHelper
      .getApplicationData(ch);
    System.out.println("doc is found");
    StreamData sd=(StreamData) StandardFvService.getStreamedObject(ch);
    //sd.retrieveStream();
    for (int j = 0; j < attachmentList.size(); j++) {
     System.out.println("there is some content");
     ApplicationData appdata = (ApplicationData) attachmentList
       .get(j);
     InputStream in = RedirectDownload.getInputStream(appdata,
       ch, true).getStream();
     Vector v=StandardFvService.getFileLocation(appdata);
     
     for(int f=0;f<v.size();f++){
      System.out.println("FileLocation==================="+(String)v.get(f));
     }
     System.out.println("---------------8888888-----------------");
     appdata.getFileName();
     System.out.println("filename======"+appdata.getFileName());
     urlvector.add(in);
     String path="c:\\download\\"+appdata.getFileName();
     downloadfile( in,  path);

 

String absoluteFileName = getTempPath() + fileName; //服务端的物理地址+文件名
 ContentServerHelper.service.writeContentStream(appdata , absoluteFileName);
