I have a method from a webservice that returns a bytearray that is an
and i want to display this as a response.
I tried create a jpg file and then display it but this doesn't work. The file is created but i cant displayed it.
arreglo = brailleText(request.getParameter("texto"),tamano); BufferedImage bufferedImage = ImageIO.read(new ByteArrayInputStream(arreglo)); File imageFile = new File("/home/antonio/services/magicsquare/image/braile.jpg"); ImageIO.write(bufferedImage,"jpg", imageFile); /// TODO output your page here out.println("<html>"); out.println("<head>"); out.println("<title>Servlet BrailleServlet</title>"); out.println("</head>"); out.println("<body>"); out.println("<img src=\"" + request.getContextPath() + "/image/braile.jpg\" />"); out.println("</body>"); out.println("</html>");
Does anyone know how to do this?
