The section of code that creates the Java classes follows:

757 StringReader in = new StringReader( xmlString );
758 XMLStreamReader reader = StAXUtils.createXMLStreamReader( in );
759
760 try
761

{ 762 ManageContentRequest.Factory.parse( reader ); 763 }

764 catch ( Exception e )
765

{ 766 this.log.error( xmlString ); 767 this.log.info( e.getLocalizedMessage(), e ); 768 e.printStackTrace(); 769 }

The portion of the Java-Axis2 class that is involved in the stacktrace is

java.util.ArrayList list25 = new java.util.ArrayList();

// Process the array and step past its final element's end.
list25.add(reader.getElementText());

//loop until we find a start element that is not part of this array
boolean loopDone25 = false;

while(!loopDone25){
// Ensure we are at the EndElement
while (!reader.isEndElement())

{ reader.next(); }

// Step out of this element
reader.next();

// Step to next element event.
while (!reader.isStartElement() && !reader.isEndElement())
reader.next();

if (reader.isEndElement())

{ //two continuous end elements means we are exiting the xml structure loopDone25 = true; }

else {
if (new javax.xml.namespace.QName("http://ablis.business.gov.au/2011-09/Data","URL").equals(reader.getName()))

{ list25.add(reader.getElementText()); }

else

{ loopDone25 = true; }

}
}

// call the converter utility to convert and set the array
object.setURL((org.apache.axis2.databinding.types.URI[])
3864 org.apache.axis2.databinding.utils.ConverterUtil.convertToArray(
org.apache.axis2.databinding.types.URI.class,list25));
