{noformat}

Detail: 
we serialize the KnowledgeBase by the following code.
{noformat}
        ByteArrayOutputStream byteStream = new ByteArrayOutputStream();
        ObjectOutputStream out = new ObjectOutputStream(byteStream);
        out.writeObject(_kbase);
        out.close();
        setKnowledgeBaseContents(byteStream.toByteArray());
{noformat}

we deserialize the knowledgebase by the following code.
{noformat}
          ByteArrayInputStream bi = new ByteArrayInputStream(info.getData());
          ObjectInputStream oi = new ObjectInputStream(bi);
          kbase = (KnowledgeBase) oi.readObject();
          bi.close();
          oi.close();
{noformat}
