Acceleo generator in standalone mode [message #1386145]

Hello,

i try to use the Acceleo generator outside of Eclipse (by calling java Generate from commandline), without any luck.
The following descriptions are also not working:
http://wiki.eclipse.org/Acceleo/FAQ#How_can_I_compile_my_mtl_files_in_a_standalone_environment.3F
http://help.eclipse.org/juno/index.jsp?topic=%2Forg.eclipse.acceleo.doc%2Fpages%2Freference%2Fstandalone.html

I'm trying to use Generate.java (that is automatially created in Eclispe). It compiles, but executing it, i get this error:

--------------------------------------------

at org.eclipse.emf.ecore.resource.impl.ResourceSetImpl.demandLoadHelper(ResourceSetImpl.java:274)
... 5 more
--------------------------------------------

To execute it (run.bat), i specify all the jar files, found in the Eclipse\plugins folder (with C:\eclipse\plugins\*; in the classpath argument of Java).
The model i want to transform is sample2.ecore.
Generate.class is located in the package hierarchie: at.ac.wu.acceleo.nx
It is called with: java -classpath "C:\eclipse\plugins\*;.;" at.ac.wu.acceleo.nx.Generate "D:\acceleo\at.ac.wu.acceleo.nx\src\sample2.ecore" "D:/out"
(surprisingly Generate.class looks for generate.emtl and NOT for .mtl, like in Eclispe)

In Eclipse in Activator.java (function public void start(BundleContext context)) i write the content of 'context' in a file to figure out, how the generator is invoked...

Should i specify a parameter of Generate.class in standalone mode?

Thank you in advance for your help,
Daniel

Please use the eclipse.modeling.m2t forum to ask questions about Acceleo.
