deserialization problem: unexpected child element
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">
<soapenv:Body>
<soapenv:Fault>
<faultcode>soapenv:Server.userException</faultcode>
<faultstring>org.xml.sax.SAXException: SimpleDeserializer

Re: deserialization problem: unexpected child element
Posted by MKW <m....@ru.ac.za>.
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?

Re: deserialization problem: unexpected child element
Posted by Anne Thomas Manes <at...@gmail.com>.
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?
