Image rendering components

[Mohan Radhakrishnan <Mo...@hclcomnet.co.in>]

Hi,
        I have a StringBuffer of HTML that includes a generated image. My
DTO carries it to the presentation tier. How is usually included in the JSP
stream ? Tags ?
bye,
Mohan

Your action could write the html from your DTO directly to the response,
without the need to forward to a JSP.

this would go along the lines of:
<snip>
  inStream = docLib.getDataStream();
  ByteArrayOutputStream out =new ByteArrayOutputStream();
        byte[] buf = new byte[4096];
  int i = -1;
  while ((i = inStream.read(buf))!=-1){
   out.write(buf,0,i);
  }
  response.setContentType(docLib.getContentType());
        response.setIntHeader("Content-length",docLib.getSize().intValue());

response.setHeader("Content-disposition","attachment;filename="+docLib.getFi
lename());
     ServletOutputStream sout = response.getOutputStream();
  out.writeTo(sout);
  out.flush();
        out.close();
        return null;
</snip>

or something similar where you'd be writing the bytes of html string out.
