File Open: Asks twice to open document in IE6.0(Weblogic server with JSPs deployed)

Question

          HI,
          This may not be appropriate question on this discussion forum. But in case if
          somebody has answer for this, please let me know:
          Problem:
          I am trying to open some documents in my JSP(JSPs are deployed on Weblogic5.1)
          where a BLOB will be streamed and written to ServletOutputStream. Some piece of
          code which does this, I have pasted below:
          // start attachmentviewer.jsp
          <% BufferedInputStream is = null;
          BufferedOutputStream os = null;
          response.setContentType(mimeType.trim()); // say application/msword for word document
          response.setHeader("Content-Disposition","attachment; filename=\""+attachmentViewBean.getAttachmentName()+
          "\";"); //bean method gets attachment name
          is = new BufferedInputStream(attachmentViewBean.getAttachment().getBinaryStream());
          // gets blob
          os= new BufferedOutputStream(response.getOutputStream());
          byte[] buff = new byte[6500];
          int bytesRead;
          out.clearBuffer();
          while(-1 != (bytesRead = is.read(buff, 0, buff.length)))
          os.write(buff, 0, buff.length);
          %>
          // end attachmentviewer.jsp
          I am closing handles etc. after this.
          This works fine in Netscape6.0 in which
          a dialog box prompts user to open/save
          document once and does correspondigly
          after user action.
          In IE 6.0 first file open dialog comes
          informing its open/saving
          attachmentviewer.jsp. Upon clicking open it
          again opens another dialog box
          informing to open/save for actual file
          name put in response's setHeader method.
          I observed this to happen in IE6.0, but
          works fine in IE5.5 prompting user once.
          If anyone has any idea/suggestions/tips
          about this, please lemme know.
          Thanks,
          Yogesh
          

Answer 1

i was able to solve it by clearing the output stream (jsp page - out.clear() ) before using it, even resetting the jsp response does the trick..
