Re: Show Bolb image data by Servlet

I do the following way:
First set the content type of the servlet as:

private static final String CONTENT_TYPE = "image/jpeg";
response.setContentType(CONTENT_TYPE);

Then the following:

while(rs.next()){

      BLOB l_mapBLOB = ((OracleResultSet)rs).getBLOB(1);
      InputStream in = l_mapBLOB.getBinaryStream();

      //InputStream in = rs.getBinaryStream(1);
      ByteArrayOutputStream boas = new ByteArrayOutputStream();
      byte b[] = new byte[1024];
      while(true) {
        int bytes = in.read(b);
          if(bytes==-1) {
            break;
          }
          boas.write(b, 0, bytes);
      }
      b = boas.toByteArray();
      response.setContentLength(b.length);
      out.write(b,0,b.length);
 }

Hope this will help you.
Regards,
Moiz

The image when you retrieve, store it in a physical location on the
server .jpg or whichever image format. And call it how you use in html
page.
