Hi there,
I am new to axis2 with XMLBean data binding, please help me with the
following issue.
I modified the quickstart sample XMLBean program to try a WSDL with the
following types. The type US-Address is a derived from type Address. I would
like to create a service operation updateAddresses to change addresses of a
company based on a symbol. The addresses is an array that can take either
Address or USAddress instances.
<xs:complexType name="Address">
<xs:sequence>
<xs:element name="name" type="xs:string" minOccurs="0"/>
<xs:element name="street" type="xs:string"/>
<xs:element name="city" type="xs:string"/>
</xs:sequence>
</xs:complexType>
<xs:complexType name="US-Address">
<xs:complexContent>
<xs:extension base="ipo:Address">
<xs:sequence>
<xs:element name="state" type="ipo:US-State"/>
<xs:element name="zip"
type="xs:positiveInteger"/>
</xs:sequence>
</xs:extension>
</xs:complexContent>
</xs:complexType>
<xs:element name="updateAddresses">
<xs:complexType>
<xs:sequence>
<xs:element name="symbol" type="xs:string"
nillable="true"/>
<xs:element name="addresses" type="ipo:Address"
maxOccurs="unbounded"/>
</xs:sequence>
</xs:complexType>
I used WSDL2JAVA with XMLBean data binding to generate the skeleton
and stub code. All looks great and the SOAP exchange looks fine too.
In the client code, I created one instance if USAddress and one
instance of Address and put them into the addresses list. In the SOAP
request message, the instances are as shown as follows below. Note,
xsi-type for the instance indicate the correct types which is nice.
<soapenv:Body>
<updateAddresses xmlns="http://quickstart.samples/xsd";>
<symbol>XYZ</symbol>
<addresses
xmlns:xsi="http;//www.w3.org/2001/XMLSchema-instance"
xmlns:xsd="http://quickstart.samples/xsd"; xsi:type="xsd:US-Address">
<name>company name</name>
<city>Sunnyvale</city>
<state>CA</state>
<zip>94087</zip>
</addresses>
<addresses
xmlns:xsi="http;//www.w3.org/2001/XMLSchema-instance"
xmlns:xsd="http://quickstart.samples/xsd"; xsi:type="xsd:Address">
<name>company name</name>
<city>Hong Kong</city>
</addresses>
</updateAddresses>
</soapenv:Body>
The problem is when the XML object mapped into java object on the service
side, all the XML address object passed to the skeleton are all of Address
type. I would expect one instance be Address type, another be USAddress
type. Since xsi-type in the SOAP message has the right type, why the XMLBean
object is not created as the derived type? Is there any option in WSDL2JAVA
to make this work?
From the XMLBean Address java object, how can I access the xsi-type
attribute that was available in the XML string?
If I am not heading the right direction, can anyone suggest some
alternatives?
Thanks for your time!
