hello all,
I am new in acceleo,
when I created my first simple acceleo project based on my own simple metamodel, I have gotten the errors below. I will appreciate if anyone could help!
this is my code:
when I chose java application as Runner in run configuration, I got this error:
Exception in thread "main" org.eclipse.emf.ecore.resource.impl.ResourceSetImpl$1DiagnosticWrappedException: org.eclipse.emf.ecore.xmi.PackageNotFoundException: Package with uri 'http://www.example.org/kbei_metamodel' not found.

... 6 more
and when I chose Acceleo plug-in Application as Runner, I didn't get error in console, but there is not generated any code and I see these errors in error log.
best regards,
maryam

Hello Maryam,
As Ed suggested, I believe you should look at the Java class generated automatically next to your main Acceleo module.
In that class there's a method called registerPackages() where you need to register your metamodel. There are instructions there on how to do that.
Good luck!
