["BALDWIN, ALAN J [AG-Contractor/1000]" <al...@monsanto.com>]

Here is the response I'm getting, if this helps.  I've seen several people having this problem on the web, but nobody seems to have posted any fixes.

<soapenv:Fault xmlns:soapenv="http://schemas.xmlsoap.org/soap/envelope/">
	<faultcode>soapenv:Server.userException</faultcode>
	<faultstring>org.xml.sax.SAXException: SimpleDeserializer encountered a child element, which is NOT expected, in something it was trying to deserialize.</faultstring>
	<detail>
		<ns1:hostname xmlns:ns1="http://xml.apache.org/axis/">LCEVER</ns1:hostname>
	</detail>
</soapenv:Fault>

Thanks,

child element...


Hi all, I'm having an issue with Apache Axis 1.2 RC3.  It is running on Tomcat 5.0.28.  The error I'm getting is "org.xml.sax.SAXException: SimpleDeserializer encountered a child element, which is NOT expected, in something it was trying to deserialize".  I've tried tweaking the schema and wsdl but to no avail.  Nothing I do seems to get rid of this error.  I'm using a document/literal approach, as you will note below.  Is this a schema validation problem?  I have downloaded the axis source, but I haven't dug *too* deeply into it.

Can anyone help me?

Thanks a lot, 

  Alan Baldwin
