How to output audio format or other file via JSP

Couple of steps to make this happen

• First need to tell JSP you try to output other content rather than a regular html page, so you need to put the code like this at the beginning.

  <%@ page contentType="audio/mpeg" %>

• Second need to get the audio file, my below example is getting from a URL link

URL url = new URL(wsurl+filename);

        URLConnection c = url.openConnection();

        //set timeout
        //c.setConnectTimeout(2000);

        InputStream is = c.getInputStream();
        BufferedInputStream in = new BufferedInputStream(is);

        ServletOutputStream sos = response.getOutputStream();
        BufferedOutputStream bos = new BufferedOutputStream(sos);

• and then, need to write out to the servlet buffer. do something like this

         while ((i = in.read()) != -1) 
          {
              bos.write(i);
          }
  
          bos.flush();
          bos.close();
  

• finally you might need some code to handle exception. and redirect the page to an error page

   catch (Exception e) {
          out.println("An exception occured: " + e.getMessage());
          session.setAttribute("error_msg", e.getMessage()) ;
          response.sendRedirect("./Error");
  
      }
  

It seems work for me fine via this way..
