Pass Object Between Applet and JSP Page

Question

Hi all,
How can I pass an Object(such as Vector, File), rather than just string to the Applet from a JSP page?
Thank you.

Answer 1

I used Base64Encoder and Base64Decoder from servlets.com utilities.
* convert any serializable object to a String
public synchronized static String objectToString(Serializable obj) throws Exception {
    ByteArrayOutputStream bos = new ByteArrayOutputStream(100);
    ObjectOutputStream oos = new ObjectOutputStream(bos);
    oos.writeObject(obj);
    byte[]bytes = bos.toByteArray();
    bos = new ByteArrayOutputStream(); //to save the encoded String
    Base64Encoder enc = new Base64Encoder(bos);
    enc.write(bytes);
    String encodedString = bos.toString();
    //close all
    enc.close();   
    oos.close();
    bos.close();
    return encodedString;
* Recreates the object from the encoded String
public synchronized static Object stringToObject(String str) throws Exception {
    ByteArrayInputStream bis = new ByteArrayInputStream(str.getBytes());
    Base64Decoder dec = new Base64Decoder(bis);
    ObjectInputStream ois = new ObjectInputStream(dec);
    Object obj = (Object)ois.readObject();
    ois.close();
    dec.close();
    bis.close();
    return obj;
}
