Hi,

I need to use the XML metamodel to convert OWL/XML files form Protege to
use them in a particular transformation. Thus I need to have the reverse
transformation of the one used in the ODM use case from G. Hillairet to
convert owl/xmi into owl/xml.
But when I try to use XML.ecore form this use case, I've got a
NullPointerException, does anybody know why ?

Thanks,

Guillaume Gauffre

Hi Guillaume,

Can you send a trace of the raised exception and give more details about
the way you launch the transformation ?

Hi,

I changed my input model by using AM3 functionnality to inject XML
content into ecore based XML, and now it works. Do you know how to use
XML injection with both launch configuration and java code ?

Thanks

Guillaume

Hi,

the XML injection process deals with injection (TCS) and not with
transformation (ATL). Thus, you cannot use a launch config (ATL
configuration) to perform an injection.

You can inject an XML file with an ant task (am3.loadmodel specifying an
injector) or with Java code (then look at
org.eclipse.am3.ui.ActionXMLInjector class)
