I know tapestry-upload. But it need to submit. What I use is a flash/javascript fileUpload addon(SWFUpload:http://www.swfupload.org/). Files can be uploaded without submit. I set a Tapestry page to receive the file. In PHP, Struts and jsp, it works well. I just want to find a Tapestry way.
I am looking for where goes wrong. The InputStream.read() is -1 the first time calling, and the request.getContentLength() is not 0. It seems the InputStream of request has been read by Tapestry Filter or something. When it comes to me, there is nothing to read from. 2009-08-14 sohu
