I forgot to include this:

     <beanMapping
        languageSpecificType="java:com.farmsource.domain.PurchaseOrder"
        qname="impl:purchaseOrder"
        xmlns:impl="http://localhost:8080/poc-axis-server/services/MessageService"

Actually, that WSDL validated in the eclipse plugin... I was including an external wsdl into the wsdd file so that axis would not generate one for me.  I have determined that is not the problem.  

Here is what is happening now (I've been dealing with this issue for a while):  I have a "PurchaseOrder" java bean with a "description" field on it.

Again, I'm using document/literal.

If the soap message looks like this, it works:

<SOAP-ENV:Body>
   <echoMessage>
   	<description>test...</description>
   </echoMessage>
<SOAP-ENV:Body>

This does NOT work:

<SOAP-ENV:Body>
   <echoMessage>
	<PurchaseOrder>
   		<description>test...</description>
	<PurchaseOrder>
   </echoMessage>
<SOAP-ENV:Body>


When I put the PurchaseOrder node in, it breaks.  This is just a proof of concept service, but when we implement, I will need the root node in there to validate against an industry standard schema.  In this case, I'm just using PurchaseOrder.


Any ideas?  Thanks for the reply.

It looks like a disagreement in XML namespace. 

The echoMessage in the wsdl appears to be in a particular namespace,
whereas the VB6 client is sending a message in no namespace at all.  

    <echoMessage>
      <PurchaseOrder>
        <description>string</description>
      </PurchaseOrder>
    </echoMessage>


The WSDL you sent isn't a real wsdl.  It is missing a bunch of stuff?
So it is hard to say whether what I wrote above is right.

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

trying to deserialize.</faultstring>
	<detail>
		<ns1:hostname

	</detail>
</soapenv:Fault>

Thanks,

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
