HttpServletResponse, kako da posaljem dva byte[] array kroz ServletOutputStream?

^{07.05.2010. u 20:41 - pre 170 meseci}

Imam bazu u koju je upisan sadrzaj vise JTextPanes u Blob vrednosti. Java Servlet cita jedan red iz baze, pretvara u byte[] niz koji putem ServletOutputStream salje kao httpresponse appletu.
Applet otvara konekciju sa Servletom, cita byte stream, pretvara u Object stream i iz njega dobijem StyledDocument...
Ovaj kod to radi.
Problem nastaje kada iz baze citam vise redova. Svaki red je jedan byte[] array. Kako da posaljem dva ili vise byte[] array kao HttpResponse?

Code:

    public class SqlServlet extends HttpServlet {

      @Override
      public void doGet(HttpServletRequest req, HttpServletResponse resp){

                ResultSet rs=null;

                                   ***
                rs = stmt.executeQuery("select blog from tekstslika where id='1'");

                                   ***

             try{
                rs.next();
                blob=rs.getBlob("blog");
                byte[] blobData=blob.getBytes(1, (int)blob.length());
                int size = blobData.length;  // bytes to be sent
                resp.setContentLength(size);
                resp.setContentType("Content-Type");
                ServletOutputStream stream = resp.getOutputStream();
                stream.write(blobData);
                stream.flush();
              }catch(Exception e){System.out.println("3 " +e);}

       }
    }

Code:

         //   na strani klijenta
        //    APPLET

                   ***

                StyledDocument doc;
                URLConnection con=null;
                InputStream instream=null;
                ObjectInputStream ois=null;
                ByteArrayOutputStream byteArrayOutputStream=new ByteArrayOutputStream();
                ByteArrayInputStream byteArrayInputStream = null;
                try {
                      con = getServletConnection();
                      instream = con.getInputStream();
                      int c;
                      while ((c = instream.read()) != -1) {
                            byteArrayOutputStream.write(c);
                      }
                      byteArrayInputStream = new ByteArrayInputStream(byteArrayOutputStream.toByteArray());
                      ois = new ObjectInputStream(byteArrayInputStream);
                      doc= (StyledDocument)ois.readObject();
                      jTexPan.setStyledDocument(doc2);
                    }catch (Exception ex) {System.out.println(ex);}
