    Bug unmarshalling an array in a jaxrpc service

    Karen Lease Newbie

      I have a bug unmarshalling an array of objects in a jaxrpc webservice.
      Here is the incoming soap message. I am passing a collection of ProductA objects where ProductA is a subclass of Product.

      <env:Envelope xmlns:env='http://schemas.xmlsoap.org/soap/envelope/'>
       <env:Header/>
       <env:Body>
       <ns1:purchase xmlns:ns1='http://org.jboss.ws/samples/docstyle/wrapped/types' xmlns:xsi='http://www.w3.org/2001/XMLSchema-instance'>
       <String_1>Karen</String_1>
       <arrayOfProduct_2 xsi:type='ns1:ProductA'>
       <name>cyfac</name>
       <price>3000</price>
       </arrayOfProduct_2>
       <arrayOfProduct_2 xsi:type='ns1:ProductA'>
       <name>look</name>
       <price>5000</price>
       </arrayOfProduct_2>
       <arrayOfProduct_2 xsi:type='ns1:ProductA'>
       <name>GOSPORT</name>
       <price>1000</price>
       </arrayOfProduct_2>
       </ns1:purchase>
       </env:Body>
      </env:Envelope>


      The relevant part of the schema looks like this:
      <complexType name='purchase'>
       <sequence>
       <element name='String_1' nillable='true' type='string'/>
       <element maxOccurs='unbounded' minOccurs='0' name='arrayOfProduct_2' nillable='true' type='tns:Product'/>
       </sequence>
       </complexType>
      
       <complexType name='Product'>
       <sequence>
       <element name='name' nillable='true' type='string'/>
       </sequence>
       </complexType>
      
       <complexType name='ProductA'>
       <complexContent>
       <extension base='tns:Product'>
       <sequence>
       <element name='price' type='int'/>
       </sequence>
       </extension>
       </complexContent>
       </complexType>
      
       <complexType name='purchaseA'>
       <sequence>
       <element name='String_1' nillable='true' type='string'/>
       <element maxOccurs='unbounded' minOccurs='0' name='arrayOfProductA_2' nillable='true' type='tns:ProductA'/>
       </sequence>
       </complexType>


      The behavior in the service is that only the last element of the Product sequence is received in the purchase method.

      If I use the purchaseA method which expects a collection of ProductA as argument, the result is correct.

      The bug seems related to JBXB-96 which is marked as fixed. My purchase() method works with the 1.0.0.GA version of jboss-xml-binding (which was included with jboss 4.2.1.GA, jbossws-1.2.1.GA), but fails in 1.0.0.SP1 (aka CR11) which has the fix for JBXB-96. So it fails with all the jbossws-2.0.x versions.

      I also looked at the test case created for this bug (org.jboss.test.xml.XsiTypeUnitTestCase). It works, but in that case, the collection of objects is the only content of the message. I modified the test case to add a wrapper object with a member appearing before the collection. That testcase fails in the same way as my webservice; only the last element of the collection appears in the parent object.
