Top down round trip problem where wrapper elements are marked as nillable by
JAXB during WSDL generation
--------------------------------------------------------------------------------------------------------
Key: TUSCANY-2757
URL: https://issues.apache.org/jira/browse/TUSCANY-2757
Project: Tuscany
Issue Type: Bug
Components: Java SCA Axis Binding Extension
Affects Versions: Java-SCA-1.4
Environment: All
Reporter: Simon Laws
Fix For: Java-SCA-Next
With a top down scenario where a java interface is generated from WSDL, for
example, by using wsimport, and is then used in Tuscany the Tuscany code
regenerates the WSDL from the Java interface and in doing so creates XSD based
on the generated Java types. In this situation JAXB appears to assumed that the
wrapper element types are nillable. This breaks the JAXWS wrapped algorithm
that explicitly states that wrapped interface elements should not be nillable.
If I remove the generated wrapped element classes and have Tuscany generated
the WSDL based on the interface itself then it works.
Here is the WSDL. that we start with..
<wsdl:types>
<xsd:schema xmlns:xsd="http://www.w3.org/2001/XMLSchema";
targetNamespace="http://www.example.org/CreditCardPayment/";

wsimport generates a set of classes...
payment/creditcard/
AddressType
AuthorizeType
AuthorizeResponseType
CreditCardDetailsType
etc
With the Composite...
<composite xmlns="http://www.osoa.org/xmlns/sca/1.0";
xmlns:t="http://tuscany.apache.org/xmlns/sca/1.0";
xmlns:c="http://creditcard"; targetNamespace="http://creditcard";
name="creditcard">
<component name="CreditCardPaymentWSClient">
<implementation.java
class="payment.creditcard.impl.CreditCardPaymentImpl" />
<reference name="creditCardPayment">
<binding.ws uri="http://localhost:8084/CreditCardPayment"; />
</reference>
<service name="CreditCardPayment">
<!--t:binding.jsonrpc uri="/jsonrpc/CreditCardPayment" /-->
<binding.sca />
</service>
</component>
<component name="CreditCardPaymentWS">
<implementation.java
class="payment.creditcard.ws.impl.CreditCardPaymentWSImpl" />
<service name="CreditCardPayment">
<binding.ws uri="http://localhost:8084/CreditCardPayment"; />
</service>
</component>
</composite>
Running Tuscany and using the following URL
http://l3aw203:8084/CreditCardPayment?wsdl
Gives rise to the following WSDL...

<xs:element name="authorize" nillable="true" type="tns:AuthorizeType"/>

Where autorize and authorizeResponse elements are marked as nillable. This
breaks the tuscany code and causes and array out of bounds exception
