Geir Egil Hansen commented on AXIS2-1749:
-----------------------------------------
Although it is possible to do restriction by inheritance in Java (and C++),
there is no specific syntax denoting that is what is done. It's done only
programatically.
So I cannot see how to differ between restriction and extension. I think Axis2
should always use extension. Another thing; how will Axis2 generate client
code (and server code for that matter) on WSDL's using restriction and/or
extension? Haven't checked this out yet. But I'm gonna!

> During the generation of type definitions Java2WSDL of axis2-1.1 flattens
> chains of extender java data types to independent schema types without
> extending relations between them, while Axis121 stores these relations by
> <extension base"">.
> For example: say,
> class A { public String someString; public A someLink; } and
> class B extends A { public int someInt; }
> and the exposed service is:
> class MySvc { String myOp(A arg) {..} }
> Running of Java2WSDL on it:
> java2wsdl -cn MySvc -xc B
> creates 2 non-related types:
> <xs:complexType name="A">
> <xs:sequence>
> <xs:element name="someLink" type="ns:A"/>
> <xs:element name="someString" type="xs:string"/>
> </xs:sequence>
> </xs:complexType>
> and
> <xs:complexType name="B">
> <xs:sequence>
> <xs:element name="someLink" type="ns:A"/>
> <xs:element name="someString" type="xs:string"/>
> <xs:element name="someInt" type="xs:int"/>
> </xs:sequence>
> </xs:complexType>
> while B should be:
> <xs:complexType name="B">
> <xs:complexContent>
> <xs:extension base="ns:A">
> <xs:sequence>
> <xs:element name="someInt" type="xs:int"/>
> </xs:sequence>
> </xs:extension>
> </xs:complexContent>
> </xs:complexType>
> Since complexType B is not extension of ? it (the B type element) can't be
> passed as the someLink.
