(copy of a previous mail in castor-dev)
Edit the properties file : castor.properties provided in the jar file to enable namespaces to the following and then execute again ..
org.exolab.castor.parser.namespaces=true
This should work.

Hello,
This is my second attempt to use castor. In both cases I can create the java code via the .xsd file(schema). It builds under eclipse just fine. I can run the code that calls the marshal methods and it works just fine. I can test the 'well formed' and 'validity' of generated xml via xmlspy5 and it checks out ok!
But when I try to unmarshal the resultant .xml file the code generates an IllegalArgumentException.
This is an example from:
http://www.xml.com/pub/a/2002/07/24/databinding.html
It's really very straight forward, but I don't know what to do anymore!!!!
HELP HELP HELP I'm really stuck!!!!
Below is the stack dump from my current attempt:
java.lang.IllegalArgumentException: The prefix 'xml' is reserved (XML 1.0 Specification) and cannot be declared.

I'm using the Sun JRE 1.4.2_01
Heres the generated XML:

And heres the unmarshal code:
package org.dogshow;
import java.io.FileReader;
public class LoadDogShow { public static void main(String [] args) { try { FileReader reader = new FileReader("show.xml"); Show show = (Show) Show.unmarshal(reader);
System.out.println(show.getJudging()[0]. getBreed().getDog()[0].getName());
reader.close(); } catch (Exception e) { e.printStackTrace(System.err); } } }
