Instantiate static SDOs with DataFactory
Hi all,
sorry for asking, but I am not quite sure how to instantiate a generated static SDO with the DataFactory class. I have something like this:
- Person.xsd which contains the declaration of a person type
- generated interfaces, factory and impl with the XSD2JavaGenerator
- PersonFactory.INSTANCE.createPerson() works just fine
- but when I call the more abstract DataFactory.INSTANCE.create(Person.class) I get an:
Exception in thread "main" java.lang.IllegalArgumentException
at org.apache.tuscany.sdo.helper.DataFactoryImpl.create(DataFactoryImpl.java:60)
at org.apache.tuscany.sdo.helper.DataFactoryImpl.create(DataFactoryImpl.java:50)
Do I have to call something before to register my Person type or is the DataFactory only suiteable for dynamic SDOs?
Thanks for the clarification,
Philipp

Sorry, and to tie up the loose ends --- the default
DataFactory.INSTANCEmakes use of the default
TypeHelper.INSTANCE, so (barring classloader issues implied by the JavaDoc)
tying that together you now have the default DataFactory being able to find
and use your generated types.

Philip,
I think what you need is the Tuscany specific call to ...
SDOUtil.registerStaticTypes(PersonFactory.class)
The JavaDoc says ....
"Register and initialize the SDO types supported by the specified generated
factory class. This function must be called before instances of the
generated types can be created/used. The registered types will be visible in
all TypeHelper's created in the same classLoader scope as the call to this
function."
Regards, Kelvin.
