Serialize object to form.. class mismatch?

[Michael Mok <mo...@hotmail.com>]

Hi

Young Wayne posted an previous in regards to getting version mismatch error
when serializing class.

I encountered similar problem when serializing my object as well. The errors
are

java.io.InvalidClassException: java.lang.Integer; Local class not
compatible: stream classdesc serialVersionUID=1360826667802527544 local
class serialVersionUID=1360826667806852920

setSerializeOrg code is

   byte buf[] = sOrg.getBytes();
   ByteArrayInputStream bais =
       new ByteArrayInputStream(buf);
   ObjectInputStream ois = new ObjectInputStream(bais);
   this._organisation = (Organisation)ois.readObject();
   ois.close();


getSerializeOrg code is

        ByteArrayOutputStream baos =
                new ByteArrayOutputStream(100);
        ObjectOutputStream oos = new ObjectOutputStream(baos);
        oos.writeObject(this._organisation);
        byte buf[] = baos.toByteArray();
        oos.close();
        return new String(buf);



Any idea or workaround?

TIA
