Roshani:
I'm not sure why you're getting this error. However, I will advise you not
to use the static 'Marshaller.marshal' method. It will not pick up your
mapping.xml file. You should instantiate your own mapping and marshall your
objects with code that looks something like this:
private static org.exolab.castor.mapping.Mapping sMapping = null;
private static synchronized void initMapping() throws Exception {
sMapping = new org.exolab.castor.mapping.Mapping();
String mappingUrl = "mapping.xml";
sMapping.setBaseURL(mappingUrl);
sMapping.loadMapping(mappingUrl);
}
private static void toXml(Object obj) throws Exception {
if (sMapping == null) { initMapping(); }
Marshaller converter = new Marshaller(new
java.io.PrintWriter(System.out));
converter.setMapping(sMapping);
converter.setMarshalAsDocument(addXmlTag);
converter.marshal(object);
}

| I am getting the following error:
|
| Thread[main,5,main] (Alive): Uncaught exception
