Hello,
Just an update, I have confirmed that it is the switching of the TCCL that is
the culprit. Switching the TCCL back to the webapp loader just before invoking
Tuscany, results in this code working.

Hello,
I'm receiving an NPE in ModelPackageImpl. because line 2735 is
returning null for "theXMLTypePackage". Later on 2749 a NPE occurs. I
know DAS works by it self and so this code has been executed
successfully. Past experience with SDO I recall some sensitively to
classloaders and TCCL. So in ModelPackage I tried the following :
this.getClass().getClassLoader()
(org.apache.catalina.loader.WebappClassLoader) WebappClassLoader
delegate: false
repositories:
/WEB-INF/classes/
----------> Parent Classloader:
[EMAIL PROTECTED]
Thread.currentThread().getContextClassLoader()
(org.apache.axis2.util.MultiParentClassLoader)
[org.apache.axis2.util.MultiParentClassLoader]
So it seems that classloader does not equal TCCL.
Trying to track down where axis is doing this and see if it can be
avoided. But could this result in this behavior ? If yes and we can't
easily get axis to not switch TCCL, any thoughts how to avoid in SDO?
