    copied!<p>Okay, so I have created a music uploading website that uploads OGG music. It also has an audio tagger incorporated. I also put the album art into my database as a string.</p> <p>Now, I want to display that string (representing my album art) to my JSP:</p> <pre><code>@WebServlet(name = "LoadAlbumArt", urlPatterns = { "/LoadAlbumArt" }) public class LoadAlbumArt extends HttpServlet { /** * Processes requests for both HTTP &lt;code&gt;GET&lt;/code&gt; and &lt;code&gt;POST&lt;/code&gt; methods. * @param request servlet request * @param response servlet response * @throws ServletException if a servlet-specific error occurs * @throws IOException if an I/O error occurs */ protected void processRequest(HttpServletRequest request, HttpServletResponse response) throws ServletException, IOException { response.setContentType("image/jpg"); try { OutputStream outputStream = response.getOutputStream(); DBConnector bConnector = new DBConnector(); PreparedStatement preparedStatement = bConnector .Connect("SELECT * FROM devwebmp3.musicdatabase where musicno = ?"); preparedStatement.setInt(1, Integer.parseInt(request.getParameter("musicno"))); ResultSet resultSet = preparedStatement.executeQuery(); Blob blob = null; String imagestring = null; while (resultSet.next()) { imagestring = resultSet.getString("albumart"); } //BufferedImage bi = ImageIO.read(ImageIO.createImageInputStream(new ByteArrayInputStream(Base64Coder.decode(imagestring.toCharArray())))); //outputStream.write(blob.getBytes(1, (int) blob.length())); byte[] hello = Base64Coder.decode(imagestring); //ImageIO.write(bi, "jpg", outputStream); //System.out.println("byte" + hello); outputStream.write(hello); outputStream.flush(); outputStream.close(); } catch (Exception e) { // ... } // ... } } </code></pre> <p>In addition, this is the java servlet page:</p> <pre><code>src=&lt;%="\"LoadAlbumArt?musicno="+request.getParameter("musicno") +"\""%&gt;&gt; </code></pre>
