take this example
/*contents of base class Works*/
package test;
public class Works
{
public int intValue=0;
public int getInt() { return this.intValue; }
}
/*contents of base class subWorks */
package test;
public class subWorks extends Works
{
public int intValue=1;
@Override
public int getInt() { return this.intValue; }
}
/*driver */
package test;
import test.Works;
import test.subWorks;
public class fubar
{
//now a test driver to determine what happens when a subclass is upcasted
public static void main(String [] args)
{
test.Works w =new test.Works();
test.subWorks s =new test.subWorks();
System.out.println("The original base class Works produces"+w.getInt());
System.out.println("The subclass subWorks produces "+s.getInt());
//now some upcasting
Works upcast=(subWorks)s;
System.out.println("The upcasted subclass produces"+upcast.getInt());
} //end main
} //end fubar class
classes>java -classpath .;%CLASSPATH% test.fubar
The original base class Works produces0
The subclass subWorks produces 1
The upcasted subclass produces1
/* the subclass when upcasted does NOT take on the characteristics of the
parent base class */

Subject: RE: [AXIS2]. axis2. xsi:type object mapping does not work
Hi,
Yes you are right superclass could not be cast to subclass, but in my example I
am passing Subclass to the method which takes Superclass as an argument, which
is fine.

I am experiencing some problems converting XML requests on the server side, in
case XML requests contain xsi:type parameter.
The setup is following
Two objects:
ObjectSubClass extends ObjectSuperClass
A webservice with a method: getObject(ObjectSuperClass obj)
In wsdl these objects defined in the following way:
<xs:schema attributeFormDefault="qualified" elementFormDefault="qualified"
targetNamespace="http://mypackage.com/xsd";>
<xs:complexType name="ObjectSuperClass">
<xs:sequence>
<xs:element minOccurs="0" name="id" nillable="true" type="xs:string"/>
<xs:element minOccurs="0" name="name" nillable="true" type="xs:string"/>
</xs:sequence>
</xs:complexType>
<xs:complexType name="ObjectSubClass">
<xs:complexContent>
<xs:extension base="ax21:ObjectSuperClass">
<xs:sequence>
<xs:element minOccurs="0" name="phone" nillable="true" type="xs:string"/>
</xs:sequence>
</xs:extension>
</xs:complexContent>
</xs:complexType>
</xs:schema>
>From the client I am calling this method by passing to it subclass –

ObjectSubClass obj = new ObjectSubclass();
obj.setId(“some id”);
obj.setName(“some name”);
obj.setPhone(“some phone”);
getObject(obj);
In the request XML object is represented like that:
<obj xsi:type="q1:ObjectSubClass" xmlns:q1="http://mypackage.com/xsd";>
<id>1</id>
<name>test</name>
<q1:phone>123</q1:phone>
</obj>
But on the server side no matter if I am passing instance of ObjectSuperClass
or instance of ObjectSubClass I am getting always instance of superclass
ObjectSuperClass, even when xsi:type specifies that object is of subclass
ObjectSubClasstype. As a result I am not getting values present on
ObjectSubClass and getting only values defined in superclass ObjectSuperClass.
hi,
may be i'm wrong, i'm still a newbe here. :)
but, didn't the casting of the superclass object to the subclass object work?
thanks,
Same structure worked fine in axis1 ans xsi:type was respected.
Maybe it is some configuration in axis2.
I would be really thankful for any help.
