Saving XML File - Error

[Tantra]

I'm having problems saving an XML file.

I have a JTree that I am changing to an object, then saving to XML via the XMLEncoder. This was working fine when I was just doing it locally, but now I'm doing it over the network.

I send the JTree as an object over the network to the server. The server then saves it. Here is the code:

	public void saveFile() {
		try {
			inStream = new ObjectInputStream(cSocket.getInputStream());
			Object tree = fetchObject(inStream);
			System.out.println("recieved >>" + tree);
			String fileName = "example.xml";
			File f = new File(fileName);
			XMLEncoder e = new XMLEncoder(new BufferedOutputStream(
					new FileOutputStream(f)));
			e.flush();
			e.writeObject(tree);
			e.close();
		} catch (IOException io) {
			System.out.println("I/O error");
		}
	}

	public static Object fetchObject(ObjectInputStream ois) throws IOException {
		Object in = null;
		try {
			in = ois.readObject();
			// Print data
			System.out.println("Incoming packet --> " + in);
		} catch (ClassNotFoundException cnf) {
			System.out.println("unrecognized object type");
		}
		return in;
	}

The server gets the following error:

at java.beans.XMLEncoder.writeExpression(Unknown Source)
at java.beans.PersistenceDelegate.writeObject(Unknown Source)

The resulting XML file is:

<?xml version="1.0" encoding="UTF-8"?>
<java version="1.5.0_06" class="java.beans.XMLDecoder">

Where it should be much longer.

Any ideas what I'm doing wrong?

Answered my own question and figured I'd post it here. My error was in the client. You cannot export while a node in the JTree is selected so I had to use a method to unselect all, then save.
