is StylesheetRoot serializable?

["Sergey S. Kljopov" <kl...@wetellyou.com>]

Good Day!

Im trying to serialize/deserialize StylesheetRoot:

44.     stSheet = processor.processStylesheet(new
XSLTInputSource("/tmp/page.xsl"));
45.   ByteArrayOutputStream baos = new ByteArrayOutputStream();
46.   ObjectOutputStream oos = new ObjectOutputStream(baos);
47.   oos.writeObject(stSheetSite);
48.
49.   h.put("page", baos);
50.
51.   byte[] buf = h.get("page").toString().getBytes();
52.   ByteArrayInputStream bais = new ByteArrayInputStream(buf);
53.   ObjectInputStream ois = new ObjectInputStream(bais);
54.   stSheetC = (StylesheetRoot)ois.readObject();

This code works some hours before.
Then when i recompile this, i recieve following notifications:

java.io.NotSerializableException:

What happens? I'm using xalan1.2 & xerces1.3


For interests: at xalan1.1 i'm recieve following:
java.io.InvalidClassException: org.apache.xalan.xpath.XPath; Local class not

Do you have any ideas about this? So can you suggest me how to clone
StylesheetRoot object with faster way than serialize/deserialize it?
