Subject: Can JAXB/XMLBeans work with axis binding now
Hi,
I noticed that in the helloworldws sample, now only SDO gets used.
If I want
to use JAXB/XMLBeans instead of SDO, what shall I do then?
It's simple, just declare a component reference wired to the
composite reference with the ws (axis2) binding. For the interface
of your component reference, annotate it with @DataType
(name="org.apache.xmlbeans.XmlObject") or @DataType
(name="javax.xml.bind.JAXBElement").
This reminded me to pick up the discussion of where we specify the
data binding. I think this only should be specified when using Java
as an IDL really. I know Jeremy is going to add that we should allow
this to be specified in the implementation for people that cast from
a strongly typed parameter to a loosely typed one (e.g. DataObject)
so I'm going to pre-empt him ;-) I'm pretty sure people agree this is
bad programming practice/design so the question is whether we
accommodate them. While we may "support" this in terms of it works,
we should never advertise it in practice. Anyway, this sounds like we
should spin this discussion into a separate thread so Raymond, maybe
you want to pick it back up in another email?
For example,
@Remotable
@DataType(name="javax.xml.bind.JAXBElement")
public interface JAXBInterface {
Address getAddress(Customer);
}
@Remotable
@DataType(name="org.apache.xmlbeans.XmlObject")
public interface XMLBeansInterface {
Address getAddress(Customer);
}
To be honest, I haven't had a chance to perform the integration
test for JAXB and XMLBeans. But I would be glad to help you if you
run into any issues.
Li, I think it would be great if we can get some of the JAXB and
XMLBeans stuff working.
Basically, I know I may need to register the SCDL of JAXB/XMLBeans
to my
Tuscany runtime, and replace some configurations such as
@DataType(name="commonj.sdo.DataObject") and <dbsdo/> in
helloworldws with
JAXB/XMLBeans specific stuff. Is that correct? How will <dbjaxb/> and
<dbxmlbeans/>look like? The same as SDO? Also, looks like for now
there is
still no SCDL available for JAXB/XMLBeans, do you guys have any
plan to add
them?
The SCDL extension dbsdo is used to import the model for SDO which
requires a type system. For JAXB and XMLBeans, it may not be
required. If you see any requirements for such extensions, please
post this list.
I have a feeling it may be required for XBeans. Li, do you know
offhand how custom types are loaded in XBeans (and the JAXB RI for
that matter)?
Jim
Thanks,
Li
