Bjorn Townsend commented on AXIS-2399:
--------------------------------------
Looking at the source code for the exception,
/**
* There should not be nested elements, so thow and exception if this
occurs.
*/
public SOAPHandler onStartChild(String namespace,
String localName,
String prefix,
Attributes attributes,
DeserializationContext context)
throws SAXException
{
throw new SAXException(
Messages.getMessage("cantHandle00", "SimpleDeserializer"));
}
it seems pretty clear that the SimpleDeserializer is not intended to handle
nested elements. It looks like a different deserializer needs to be used, but
I think you may be going beyond SimpleAxisServer's intended capabilities. From
the Simple Axis Server class javadoc notes:
"This is a simple implementation of an HTTP server for processing SOAP requests
via Apache's xml-axis. This is not intended for production use. Its intended
uses are for demos, debugging, and performance profiling."
(http://ws.apache.org/axis/java/apiDocs/org/apache/axis/transport/http/SimpleAxisServer.html)
And it looks to me like SimpleAxisServer is designed to use only the
SimpleDeserializer. I would say you need to use a more complete server for
this application.
