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?
