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:

index.php/fa/37175/0/

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.

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.

index.php/fa/37174/0/

best regards,
maryam

Hi

This looks like the standard newbie problem.

You have not read the comments in the generate Java main program.

Thanks for your fast answer,

but I am sorry, may I ask you to explain more? I see the generate.java but I don't know what should I find in it :-)

Hi

Sorry I don't use Acceleo any more so I don;'t have an example to hand.

However my recollection is that very near the end are some very clear instructions on how to register your metamodel(s).

It is of course a pity that Acceleo does not exploit the solution that it had when editing your transformation to accurately populate the code for execution time.

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!
