Subject Re: org.xml.sax.SAXParseException: Failed to parse integer value:
Date Wed, 23 Aug 2006 12:36:49 GMT
I looked at the example code. However, it seems to have some issues: 
      public class MyTypeFactory extends TypeFactoryImpl {
        public MyTypeFactory(XmlRpcController pController) {

        private DateFormat newFormat() {
            return new SimpleDateFormat("yyyy-MM-dd HH:mm:ss.SSS");

        public TypeParser getParser(XmlRpcStreamConfig pConfig, NamespaceContextImpl pContext,
String pURI, String pLocalName) {
            if (DateSerializer.DATE_TAG.equals(pLocalName)) {
                return new DateParser(pFormat);
            } else {
                return super.getParser(pConfig, pContext, pURI, pLocalName);

        public TypeSerializer getSerializer(XmlRpcStreamConfig pConfig, Object pObject) throws
SAXException {
            if (pObject instanceof Date) {
                return new DateSerializer(newFormat());
            } else {
                return super.getSerializer(pConfig, pObject);
  DateParser and DateSerializer require the argument to be of type 'XmlRpcDateTimeDateFormat'
but in the above code it is of type 'SimpleDateFormat' which causes the 'ClascastException'
to be thrown at runtime. And I noticed that 'XmlRpcDateTimeDateFormat' is an abstract class.
How can we get an instance of it with the formatting "yyyy-MM-dd HH:mm:ss"?

  How can I implement the logic for the XML-RPC to work with 'empty' date/time values? Should
the XML-RPC automatically handle the empty date/time values as it handles the empty int values?

I wrote a section on "custom data types". See

Depends on your implementation. :-)
