Hi,

I have a application using an Ecore model. I have developped it with
eclipse 3.2 and EMF 2.2.
When I try to move to eclipse 3.4 with EMF 2.4.2 (version 2009021), I have
successfully regenerated the genmodel, and the model code. But during the
execution, when I create the objects using
ModulesFactory.eINSTANCE.createSystem(),
i have the following error:
Exception in thread "main" java.lang.NoSuchMethodError:
org.eclipse.emf.ecore.EPackage$Registry.getEFactory(Ljava/la ng/String;)Lorg/eclipse/emf/ecore/EFactory;
at
ujf.verimag.bip.Core.Modules.impl.ModulesFactoryImpl.init(Mo dulesFactoryImpl.java:36)
at
ujf.verimag.bip.Core.Modules.ModulesFactory.<clinit>(ModulesFactory.java:26)
...

What may be bad in my code?

Regards,
Anne Robert.

Anne,

It sounds like you've developed with 3.4 but are still trying to run it
on 2.2.

Hi,
Thank you for your response.

I have never imported EMF 2.1 in eclipse 3.4. But unfortunatly, it seem
that eclipse 3.4 read the eclipse 3.2 extension location.
if the configuration detail, I have:

/instance/org.eclipse.jdt.core/org.eclipse.jdt.core.classpat hVariable.EMF_CODEGEN_ECORE=/usr/local/src/cadp/eclipse/plug ins/org.eclipse.emf.codegen.ecore_2.1.0.jar

(/usr/local/src/cadp/eclipse was the eclipse 3.2 extension location)

How can I remove this extension location from eclipse 3.4 configuration?

Thanks,
Anne.

Anne,

Java->Build Path->Classpath Variables in the preferences dialog.

Thank you very much.

After this, I think I have no more link to EMF 2.1
I have rebuild another workspace from scratch to be sure. The EMF
generation have changed (not same name for enumeration constants) but I
still have the same error at runtime.

I continue to look after any other problem.

Regards,
Anne.

Anne,

So clearly you are running with an older runtime. Look carefully at
what runtime your launch configuration is using.

OK, it is now resolved.
The last EMF link was in the properties of my main java project.
I have changed it to new EMF and it works correctly.

Thank you for your help.
Regards,
Anne.
