Teemu,
The problem is caused by namespace errors. JAX-RPC is wroking
properly.
According to the WSDL description, the AR-System is producing an invalid
message. All child elements of the <{urn:TTM}execute> element are
local elements, and therefore they must be unqualified (no namespace
prefix) in the document instance. The AR-System is making all child
elements qualified.
If it's a challenge to change the way the AR-System generates the XML,
you might try specifying the default element form to be qualified. In the
<schema> definition add the following:
<schema elementFormDefault="qualified" ...>

Hi everybody!
I sent the problem description below to Java Technology Forum
"Java Technologies for Web Services" last week but haven't got
useful replies, so I decided to try here.
I'm having problems with JAX-RPC (JWSDP 1.3 & Tomcat 5.0.18 running on HP-UX).
We have an integration project going on the goal of which is to integrate
a part of our Java-based application with an external AR-System-based
application. We have released some JAX-RPC Web Services, and also written
a testbed using JAX-RPC for system testing purposes.
Everything works well when we access our Web Services using JAX-RPC
clients. But, when the AR-System tries to connect our Web Services, a
deserialization error occurs. A stack trace of the error is in the end
of this message. We are using Document-Literal encoding (AR-System can
handle only literal encodings).
I have ripped the XML contained by the HTTP request from a request
generated by the JAX-RPC clients and from a corresponding request
generated by the AR-System. The XMLs are below:
- XML generated by JAX-RPC client (works):
<?xml version="1.0" encoding="UTF-8"?>
<env:Envelope xmlns:env="http://schemas.xmlsoap.org/soap/envelope/"
xmlns:xsd="http://www.w3.org/2001/XMLSchema"
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xmlns:enc="http://schemas.xmlsoap.org/soap/encoding/"
xmlns:ns0="urn:TTM">
<env:Body>
<ns0:execute>
<FindCustomerDataInput_1>
<areaCode>050</areaCode>
<customerName>Testuser</customerName>
<maxAmount>4</maxAmount>
<password>password</password>
<queryId>Testqueryid</queryId>
<systemId>finhd</systemId>
<telNumber>555555</telNumber>
<username>username</username>
<zipCode>02210</zipCode>
</FindCustomerDataInput_1>
</ns0:execute>
</env:Body>
</env:Envelope>
- XML generated by AR-System (doesn't work):
<?xml version="1.0" encoding="UTF-8"?>
<soapenv:Envelope xmlns:soapenv="http://schemas.xmlsoap.org/soap/envelope/"
xmlns:xsd="http://www.w3.org/2001/XMLSchema"

<ns1:areaCode>050</ns1:areaCode>
<ns1:customerName>testuser</ns1:customerName>

<ns1:queryId>testqueryid</ns1:queryId>
<ns1:systemId>finhd</ns1:systemId>
<ns1:telNumber>555555</ns1:telNumber>

<ns1:zipCode>02210</ns1:zipCode>
</ns1:FindCustomerDataInput_1>
</ns1:execute>
</soapenv:Body>
</soapenv:Envelope>
The only difference seems to be the way that namespaces are used. The
AR-System's XML is a bit more crappy and unclear, but I'm not able to
see any actual mistakes in it. It's just valid XML, or is it?
Is this a bug in JAX-RPC or is there something wrong with the XML generated
by AR System? Can somebody suggest a solution for this kind of problem?
Here is the WSDL description of the Web Service:
