I think there are still issues to be flushed out for the dynamic SDO
support.
Let's first look at the proposal:
1) Create a "Composite"-scoped java component, and in the method with @Init
to call SDO APIs to register the WSDL/XSD with SDO HelperContext.
(This is doable even though it requires some extra code from the user
effort).
2) The SDO databinding needs to access the HelperContext used by application
code in step 1 so that the models can be used for the purpose of data
transformation (for example, AXIOM <--> SDO).
(I haven't figured out a good way to associate the HelperContext, probably
we need some SDO APIs to get the HelperContext instance by some keys).
There is also an issue for static SDO
(http://issues.apache.org/jira/browse/TUSCANY-2002). It's probably in the
same category as how we register dynamic SDO types.
Thanks,
Raymond

Wang,
I'm guessing the problem is probably that you need to register your
app types with the appropriate context established by the Tuscany
runtime.
Tuscany typically does this automatically, now, for static SDO. For
dynamic SDO (i.e. DataObject), you would currently put something like
this in your SCDL ( *.composite) file:
<composite ...
xmlns:dbsdo="http://tuscany.apache.org/xmlns/sca/databinding/sdo/1.0";
....>
<dbsdo:import.sdo location="wsdl/helloworld.wsdl"/>
(I looked in your zip and you don't seem to use the types in the XSD,
so I pointed to the WSDL instead... but you can have as multiple
<import.sdo> elements).
This relation between SCA and SDO scopes is defined by Tuscany, not a
spec, at the moment.

Sorry if I'm confused but I thought that <import.sdo> was deprecated and
that there was a better way to register SDO dynamic types, using the
official SDO APIs in the init method of a Java component implementation
for example. Or am I missing something?
