Problem with XML serialiser

[Wong Kok Wai <wo...@pacific.net.sg>]

The following code works in Xerces-J 1.0.4 but throws the following
exception in 1.1.0:

java.lang.IllegalStateException: SER002 No writer supplied for
serializer
 at
org.apache.xml.serialize.BaseMarkupSerializer.serialize(BaseMarkupSerializer.java:437)

    private boolean write(File file, Document doc, OutputFormat of) {
        boolean result = true;
        PrintWriter pw = null;
        try {
            pw = new PrintWriter(new BufferedOutputStream(new
FileOutputStream(file)));
            XMLSerializer xser = new XMLSerializer(pw, of);
            xser.serialize(doc);
        } catch (Exception e) {
System.out.println("SaveManager.write: " + e);
e.printStackTrace(System.err);
            result = false;
        } finally {
            if (pw != null) {
                pw.close();
            }
        }
        return result;
    }

Hi,

it looks like this question will occur more often. (Actually, I ran
into the same problem. The code worked with the old version but not with
the new one.)

However here again the solution:

The main point is that you need a DOMSerializer, i.e. the XMLSerializer
should behave like DOMSerializer. Therefore you have to call the
asDOMSerializer-method of the XMLSerializer.

So change your code in the following way:

             XMLSerializer xser = new XMLSerializer(pw, of);
	     DOMSerializer dser = xser.asDOMSerializer();
             dser.serialize(doc);

Best regards,

Theo
