JAXB - Unrecognised Element Name Exception

Question

I am not quite sure what is wrong here.
I have got a dtd file that has the following specification:
<!ELEMENT SomeElement (A,B?)>
<!ELEMENT AnotherElement (C | B)>
<!ELEMENT A(#PCDATA)>
<!ELEMENT C(#PCDATA)>
<!ELEMENT B (x,y,z)>
<!ELEMENT x(#PCDATA)>
<!ELEMENT y(#PCDATA)>
<!ELEMENT z(#PCDATA)>
And assume default binding schema.
I wrote a XML file based on the dtd and a java app to access the data.
The XML file
<SomeElement>
<A>Some Sentence</A>
<B>
<x>1</x>
<y>2</y>
<z>3</z>
</B>
</SomeElement>
<AnotherElement>
<C>123</C>
</AnotherElement>
During unmarshalling, it throws an UnrecognisedElementNameException: x
It seems that it cannot recognised element x, y and z.
I am pretty sure I have it defined in the dtd file so why is it complaining?
Can anyone shed some light on this for me?
Thanks

Answer 1

Let me attached the files. Perhaps that will ilustrate the problem better.
The dtd file
<!ELEMENT test (precondition, step+)>
<!ELEMENT precondition (description, include?)>
<!ELEMENT step (input|include)>
<!ELEMENT input (#PCDATA)>
<!ELEMENT include (testcaseid, scenarioid, (from, to?)?)>
<!ELEMENT description (#PCDATA)>
<!ELEMENT testcaseid (#PCDATA)>
<!ELEMENT scenarioid (#PCDATA)>
<!ELEMENT from (#PCDATA)>
<!ELEMENT to (#PCDATA)>
The xml file
<?xml version="1.0"?>
<!DOCTYPE test SYSTEM "abc.dtd">
<test>
<precondition>
<description>NONE</description>
</precondition>
<step>
<include>
<testcaseid>TID</testcaseid>
<scenarioid>SID</scenarioid>
<from>F</from>
<to>T</to>
</include>
</step>
</test>
The application file
import java.util.*;
import java.io.*;
import javax.xml.bind.*;
import javax.xml.marshal.*;
public class testABC {
/** Creates new testABC */
public testABC() {
* @param args the command line arguments
public static void main (String args[]) {
try{
File sFile = new File("abcfile.xml");
FileInputStream sis = new FileInputStream(sFile);
try{
Test t = Test.unmarshal(sis);
System.out.println("Completed");
}finally{
sis.close();
}catch(Exception e){
e.printStackTrace();
Assume default schema binding
The error:
Cannot recognised the element testcaseid when try to unmarshall include element
Thanks :-)
