Hello,
I'm developing an ATL transformation tool from UML to WIKI. I used class and
libraries to launch ATL programmatically, but program fails to inizialize
the EMF model handler. In particular, error comes out during the
assignation:
emfamh = AtlModelHandler.getDefault(AtlModelHandler.AMH_EMF);
because of a nullpointer exception thrown by line:
EClass EATTRIBUTE = eINSTANCE.getEAttribute();
in the EcorePackage class. Can anyone tell me something about?
Thanks in advance for your help,
exquisitus

Hi all,
I still don't know how to fix this problem. I try to launch an ATL
transformation by means of the ATLTransormations class, downloaded
with its libraries as Milan Milanovic posted. In debugging I have:
In ATLTransormations.java:
private void initEMF() {
if(emfamh == null) { // if EMF is not initialized
// Initialize EMF model handler
-------------> emfamh =
AtlModelHandler.getDefault(AtlModelHandler.AMH_EMF);
In AtlModelHandler.java:
public static AtlModelHandler getDefault(String repository)
{
AtlModelHandler ret =
(AtlModelHandler)defaultModelHandlers.get(repository);
if(ret == null)
{
if("EMF".equals(repository))
{
-----> ret = new AtlEMFModelHandler();
In AtlEMFModelHandler.java:
protected AtlEMFModelHandler()
{
useIDs = false;
removeIDs = false;
encoding = "ISO-8859-1";
bimm = new HashMap();
URL atlurl =
org.atl.eclipse.engine.AtlEMFModelHandler.class.getResource( "resources/ATL-0.2.ecore");
--> mofmm = ASMEMFModel.createMOF(null);
In ASMEMFModel.java:
public static ASMEMFModel createMOF(ModelLoader ml)
{
if(mofmm == null)
--> mofmm = new ASMEMFModel("MOF",
EcorePackage.eINSTANCE.eResource(), null, false, ml);
.....
till in EcorePackage.java:
EClass EATTRIBUTE = eINSTANCE.getEAttribute(); (NullPointer
Exception)
hoping for an answer
best regards,
exquisitus

Hi,
are you using libs which are included with ATLTransformation class bundle ?
Did you added they to the CLASSPATH ? Maybe you have some other EMF libs
in your CLASSPATH.

Hi Milan,
actually I do have some other EMF libs in my CLASSPATH, in particular:
- org.eclipse.emf.ecore_2.3.0.some_version
- org.eclipse.emf.common_2.3.0.some_version
but if I remove these and put that included with ATLTransformation class
bundle (2.1.0), errors in the rest of my program come out. The other classes
are a modeification of automatically ecore generated classes and maybe are
dipendent from EMF 2.3.0.
Is it right and, above all, what could I do?
Thanks a lot,
exquisitus

Hi,
well I can't help you with this. As you can see from the ATL Download page,
latest version of the ATL engine (i.e. emf4atl plugin in particular) is
using EMF version 2.2.1. For newer versions of the EMF you should contact
ATL team and ask them what to do.
Or you maybe can try to generate that Ecore by using EMF 2.2.1.
