[jira] CXF service returning interface implemented by multiple objects

[prud3nt <pr...@hotmail.com>]

Hi,

I have been trying to get this working for a couple of days to no avail. I
have a service that returns an interface Widget, this interface has multiple
implementations WidgetType1 and WidgetType2. I have seen some of the
examples which deal with interfaces that use the XmlJavaTypeAdapter, but am
not sure if I am using it properly since i do not just have one
implementation of the interface (UserImpl w/ User). I get null back right
now. Any examples would be greatly appreciated. Thanks.

Attached below is all the code I am using:

http://www.nabble.com/file/p16112384/Widget.java Widget.java

Pulling this off the cxf-issues list which is normally our JIRA 
notification list.....  Almost missed it.

The thing to remember is that the interface (Widget) has absolutely no 
bearing on the hierachy represented in the schema/wsdl.   You need to 
define the heirachy only with concrete types.   Thus, Widget1 and 
Widget2 will need to share a common parent. 

Alternatively, you would need to create a new bean to represent 
a "choice" of Widget1 or Widget2.  You'd need to check the jaxb spec to 
see how choices are modeled.  I don't really remember.


Next    
@ResponseWrapper(className="hw.common.Widget",   
targetNamespace="http://server.hw.demo/")
    WidgetWrapper getWidget(int id);:

I would get rid of the ResponseWrapper annotation, get rid of 
WidgetWrapper, and just return the widget:  (although this will ONLY 
work with the latest 2.1 snapshots)

@XmlJavaTypeAdapter(AnyTypeAdapter.class)
Widget getWidget(int id);


The AnyTypeAdapter would then either map the Widget interface to the 
concrete Widget1/2 base type or to the new "choice" object that you 
would need to create.
