Hi all,

I have a little unit test (see attachment) that produces this output in a file resource:

<?xml version="1.0" encoding="ASCII"?>
<xpdl2:Activities xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xmlns:xpdl1="http://www.wfmc.org/2002/XPDL1.0"
xmlns:xpdl2="http://www.wfmc.org/2008/XPDL2.1"
xmlns:xsd="http://www.eclipse.org/xsd/2002/XSD"
xsi:schemaLocation="http://www.wfmc.org/2008/XPDL2.1 http://www.wfmc.org/standards/bpmnxpdl_31.xsd"/>

When I run the test in th eclipse/junit environment, the test works fine.
When I run a "mvn clean test", the exact same test fails with

java.lang.NullPointerException
at org.eclipse.emf.ecore.xmi.impl.XMLSaveImpl.saveDataTypeMany( XMLSaveImpl.java:1742)
at org.eclipse.emf.ecore.xmi.impl.XMLSaveImpl.saveFeatures(XMLS aveImpl.java:1485)
at org.eclipse.emf.ecore.xmi.impl.XMLSaveImpl.writeTopObject(XM LSaveImpl.java:678)
at org.eclipse.emf.ecore.xmi.impl.XMLSaveImpl.traverse(XMLSaveI mpl.java:588)
at org.eclipse.emf.ecore.xmi.impl.XMLSaveImpl.save(XMLSaveImpl. java:256)
at org.eclipse.emf.ecore.xmi.impl.XMLResourceImpl.doSave(XMLRes ourceImpl.java:205)

See also previous post named "NullPointerException in XMLSaveImpl.saveDataTypeMany".

I've completely reloaded and regenerated the code from scratch, and I think the problem is that
in order to be able to refer to an XML schema (org.eclipse.xsd.XSDSchema), there's one element
that contains these methods in the interface. They are *not* annotated with the @model tag,
as they're not part of the model but only a utility reference to an XSDSchema in another resource.

XSDSchema getXSDSchema();
void setXSDSchema(XSDSchema xsdSchema);

Because of this (?), and after reloading the genmodel, the genmodel contains additional references to
XMLType (referencing platform:/plugin/org.eclipse.emf.ecore/model/xmltype.ecore) and Ecore (referencing
platform:/plugin/org.eclipse.emf.ecore/model/Ecore.ecore).

Question is, do I have to initialize these when I run maven tests in order to prevent the NullPointerException because somewhere an EPackage is
appearantly not registered?

TIA
Ronaldo

Ronaldo,

Maybe doing XMLTypePackage.eINSTANCE.eClass() will help.

If you do this same logic in the generated XyzExample.java for this
model, does that work okay.

If you care to send me a zip of the exported projects that I could use
to reproduce this locally, that's likely to be faster than trying to
come up with theories...

Hi Ed,

Tomorrow (It's evening in Holland) I'll try your suggestion.
Meanwhile, thanks for offering to help! I've bean playing with the idea but
I didn't want to bother you :)
