Here is my idea to display the pic on the webpage:
The pic is stored in DB as binary, after retrieving it, the binary data will be converted to JPEG pic. Then, the pic will be saved to the local machine automaticly. After that, I get the pic's SRC, and use html display it.
My code is as follow (not completed), some errors in it.     public static String getPayoffSRC(Services serv, long fileId)
                                                                throws FileNotFoundException,
                                                              DBException,
                                                              DbFileNotFoundException,
                                                          IOException {
        BufferedImage buffy = new BufferedImage(300, 400,
                                                    java.awt.image.BufferedImage.TYPE_INT_RGB);   
        FileOutputStream out = new FileOutputStream(serv.getFileManager().getFileDb(fileId).getFileName());
        JPEGImageEncoder jencoder = JPEGCodec.createJPEGEncoder(out);
        JPEGEncodeParam enParam = jencoder.getDefaultJPEGEncodeParam(buffy);
        enParam.setQuality(1.0F, true);
        jencoder.setJPEGEncodeParam(enParam);
        jencoder.encode(buffy);
        out.close();
        return Pic's SRC,
    }
