Confused...
Hi Amila,
Few days back, Sathija asked the question about polymorphism support in
Axis2 for POJO. You guys have replied that POJO service does'nt support
the polymorphism but ADB client does give full support to polymorphism,
however, in this "http://ws.apache.org/axis2/1_0/adb/adb-howto.html#deep"
document it is clearly mentioned that
"ADB is meant to be a 'Simple' databinding framework and was not meant to
compile all types of
schemas. The following limitations are the most highlighted.
1. Complex Extensions and Restrictions, Simple Extensions and Restrictions
are not supported.
2. xsi:type based deserialization is not supported. Hence extension based
structures that use
xsi:type attribute may fail."
Iam was trying with some code also. But iam not successful yet.
So, should i consider that ADB does'nt support polymorphism at all?
I have communicated with Dennis on this issue and he suggested me to ask
you. Awaiting for your response.
Thanks,
-Ajay

Simply adding the SubRetObject definition to the WSDL does not influence wsdl2java to produce the associated classes. I had to add a webmethod stub that contained references to the subclass (SubRetObject) before wsdl2java was able to produce the correct service objects. Is there someway to generate objects for classes not included in a webmethod interface? I ran into the same problem in DotNet.

Martin,
I am not exactly sure what you are asking, and whether this is a general
WSDL question, or a question pertaining to the implementation of
polymorphism.
You use the term "entity". Are you talking about attributes of the
element WSDL tag? We typically see the attributes minoccurs and
maxoccurs also included in the element tag.
I have included the WSDL to my test service which I have used to
demonstrate polymorphism. The service has one webmethod:
BaseRetObject MorphThis(BaseParmObject inPoly);
I have conducted experiments which have a client create a SubParmObject
(extends BaseParmObject) and pass it in to the MorphThis method. The
service takes the data and stuffs it in a SubRetObject (extends
BaseRetObject) before returning it to the client.
Thanks, Dave

Good Evening Dave
looking quickly at the WSDL A defined service has 1+ Binding/Port
combination for each location
e.g.
<wsdl:service name="StockQuoteService">
<wsdl:port name="StockQuoteServiceSOAP11port"
binding="axis2:StockQuoteServiceSOAP11Binding">
<soap:address
location="http://localhost:8080/axis2/services/StockQuoteService" />
</wsdl:port>
so looking at the example of binding of StockService which has
binding="axis2:StockQuoteServiceSOAP11Binding"
(as we have been shown binding StockQuoteServiceSOAP11Binding has 1
PortType
called 'StockQuoteServiceSOAP11port')
PortType has input and output messages
<wsdl:portType name="StockQuoteServicePortType">
<wsdl:operation name="getPrice">
<wsdl:input message="axis2:getPriceMessage" />
<wsdl:output message="axis2:getPriceResponseMessage" />
</wsdl:operation>
The inputMessage getPriceMessage has a definition which contains one or
more
part names
<wsdl:message name="getPriceMessage">
<wsdl:part name="part1" element="ns:getPrice" />
</wsdl:message>
the localpart element getPrice has the message getPrice which is a
complexType defined of even more elements
<xs:element name="getPrice">
<xs:complexType>
<xs:sequence>
<xs:element name="symbol" nillable="true" type="xs:string" />
</xs:sequence>
</xs:complexType>
</xs:element>
Any other entities which getPrice does not need (other than symbol) is
extraneous to the run characteristics of the operation and are not
identified or carried by the message
Are you envisioning a need to carry any other entity?..if so how should
the
message identify these characteristics ?

Re: Re: Confused...
Posted by dk...@microstrategy.com.
I have recently used Axis2 1.2 wsdl2java to process some Dotnet specific WSDL to produce the necessary service classes to demonstrate polymorphism.
For example, in that WSDL, there is a base class (BaseRetObject), and a sub class (SubRetObject) which extends BaseRetObject.
<s:complexType name="BaseRetObject">
<s:sequence>
<s:element minOccurs="0" maxOccurs="1" name="baseRetStr" type="s:string" />
<s:element minOccurs="1" maxOccurs="1" name="baseRetInt" type="s:int" />
</s:sequence>
</s:complexType>
<s:complexType name="SubRetObject">
<s:complexContent mixed="false">
<s:extension base="tns:BaseRetObject">
<s:sequence>
<s:element minOccurs="0" maxOccurs="1" name="subRetStr" type="s:string" />
</s:sequence>
</s:extension>
</s:complexContent>
</s:complexType>
There is a webmethod which simply returns the BaseRetObject. The (Java) service code creates a SubRetObject and returns it as a BaseRetObject. The (DotNet) client receives the BaseRetObject, checks to see its type (using C# "is" operator) and successfully casts it. TcpTrace shows that the return object is serialized as a SubRetObject so that all data is included.
The real problem that I am running into is that wsdl2java will not produce the necessary objects for SubRetObject unless it is used in a webmethod interface. Simply adding the SubRetObject definition to the WSDL does not influence wsdl2java to produce the associated classes. I had to add a webmethod stub that contained references to the subclass (SubRetObject) before wsdl2java was able to produce the correct service objects. Is there someway to generate objects for classes not included in a webmethod interface? I ran into the same problem in DotNet.

Ajay,
Please use latest Axis2 1.2 Release Candidates / Nightly. 1.0 is very
old and definitely does not support polymorphism. If you run into
problems, please log a JIRA.
