Re: deserialization problem: unexpected child element

Thanks, Anne.

I looked up similar examples and found they had used NMTOKEN, but I had doubts about that (wasn't sure why the examples I'd seen had used it) and have since changed it back to string. I tried separating out the pos bit (see below for the change) in the hope that it might be a namespace problem and this would solve it - but it didn't. I'm inferring from your comments about the accuracy of the wsdl and the soap messages that it's more of a deserialization problem at the server end, after the message has been received, and not that the wsdl is somehow badly expressed, even though it's accurate?

The WSDL appears to be valid, and the SOAP message matches the WSDL
description. (The SOAP Body contains only one child element,
<storeEntryInDB>, which in turn contains one child element, <de>,
which in turn contains three child elements, <headword>, <plural>, and
<pos>.)

Is there a reason why you've defined <pos> as a restriction of NMTOKEN
rather than of string?

I've got the following Server.userException exception I don't know how
to handle because I'm not sure what's caused it:
"org.xml.sax.SAXException: SimpleDeserializer encountered a child
element, which is NOT expected, in something it was trying to
deserialize".  I'm assuming it was a fault in the request message caused
by the fact that it is actually sending 3 child elements (as parts of
the DictEntry) rather than the one-liner (DictEntry) that the wsdl
states?? The return message was only a string so I doubt that was the
problem?? If that is the case, can't the deserializing mechanism see
that there are 3 child parts to it from the schema type definition? Do I
need to include all the child elements at each stage???

I mostly hand-coded the wsdl (which I've checked is valid) and have just
tested it with soap messages.

I've attached the wsdl at the end.

I sent this SOAP message:
<SOAP-ENV:Envelope
xmlns:SOAP-ENV="http://schemas.xmlsoap.org/soap/envelope/";>
 <SOAP-ENV:Header/>
    <SOAP-ENV:Body>
        <storeEntryInDB xmlns="http://dct/types";>
            <de xmlns="">
                <headword>dance</headword>
                <plural>dances</plural>
                <pos>noun</pos>
            </de>
        </storeEntryInDB>
    </SOAP-ENV:Body>
</SOAP-ENV:Envelope>

and got back this SOAP response:
<soapenv:Envelope xmlns:soapenv="http://schemas.xmlsoap.org/soap/envelope/";
    xmlns:xsd="http://www.w3.org/2001/XMLSchema";
    xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance";>

            <faultstring>org.xml.sax.SAXException: SimpleDeserializer

                which is NOT expected, in something it was trying to
