Hi,
It seems like I'm missing something obvious, but I've been unable to create an instance of DynamicJAXBContext using EclipseLink 2.1.1, jxc 2.2.1, and these schema files:
http://metadata.dod.mil/mdr/ns/DDMS/2.0/DDMS-v2.0.zip
The calling code:
File schema = new File("src/main/resources/DDMS_2.0/ns/DDMS/2.0/DDMS-v2_0.xsd");
StreamSource ss = new StreamSource(schema);
DynamicJAXBContext c = DynamicJAXBContextFactory.createContextFromXSD(ss, null, null, null);
The stack trace:
Exception in thread "main" java.lang.NullPointerException

And the pom.xml

I already set up java.endorsed.dirs to point to the jaxb 2.2.1 api and I've tried various versions of EclipseLink. Nothing seems to work. And the source for XJCJavaClassImpl does not seem to be in maven.
