Examples of java.io.ByteArrayOutputStream.writeTo()

java.io.ByteArrayOutputStream.writeTo()
Take the contents of this stream and write it to the output stream out. @param out An OutputStream on which to write the contents of this stream. @throws IOException If an error occurs when writing to output stream

      response.setContentType("application/pdf");
      // the contentlength is needed for MSIE!!!
      response.setContentLength(baos.size());
      // write ByteArrayOutputStream to the ServletOutputStream
      ServletOutputStream out = response.getOutputStream();
      baos.writeTo(out);
      out.flush();
        }
        catch(Exception e) {
          isError(response.getOutputStream());
