Bug unmarshalling an array in a jaxrpc service
klease Dec 2, 2007 11:14 AMI 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.
