Hello,
I use Acceleo (SDK 3.1.0.v20110601-0321).
I want to use my generator without eclipse. In eclipse my generator works. I have exported my generator in a runnable jar file. My generator contains java services. When I launch the jar:
$ java -jar Gen2cpp.jar
I get the following exception :
java.lang.IllegalArgumentException: invalid relative pathName: rsrc:fr/cpp/generator/generate.emtl
at org.eclipse.emf.common.util.URI.createFileURI(URI.java:856)

at org.eclipse.jdt.internal.jarinjarloader.JarRsrcLoader.main(JarRsrcLoader.java:58)
What does it mean? How can I fix it? Is there a good way to create a valid runnable jar file?
Thanks for your answers.

how can Thibaut run his jar file without specifying the 2 main arguments ? did you (Thibaut) use the initialize method of the Generate class?
Have a look at the generated Java launcher class of your generator. The message is coming from the "main" method. If you want to always use those two parameters, feel free to modify the generated Java class.

why Acceleo looks for generate.emtl, is this means that Acceleo Compiler can not parse my generate.mtl ? it is the template created by default (contains only [aclass.name/])
The Acceleo compiler is used by the Acceleo tooling to compiled Acceleo modules ("mtl" files) into "emtl" files. In order to run a generation, you need those mtl files. They should be in the "bin" folder of your Acceleo project. If you have exported your Acceleo project as a "jar", you should make sure that the "emtl" files are inside.

Hi,
In the generated Java launcher, the method "registerResourceFactory" should call "super.registerResourceFactory" to ensure that the necessary resource factories used by Acceleo are registered. Are you sur ethat the call to "super.registerResourceFactory" has not been removed ? Otherwise, you'll need to register the following resource factories:
resourceSet.getResourceFactoryRegistry().getExtensionToFactoryMap().put("ecore", new EcoreResourceFactoryImpl());
resourceSet.getResourceFactoryRegistry().getContentTypeToFactoryMap().put(IAcceleoConstants.BINARY_CONTENT_TYPE, new EMtlBinaryResourceFactoryImpl());
resourceSet.getResourceFactoryRegistry().getContentTypeToFactoryMap().put(IAcceleoConstants.XMI_CONTENT_TYPE, new EMtlResourceFactoryImpl());
Acceleo compiled modules (emtl files) are the abstract syntax tree of the Acceleo module serialized as an EMF model so we need resource factories for those "models".

Hi Stephane,
I am getting the similar exception while running an "One Jar" runnable jar.
I am using Acceleo 3.3.0 RC2 on Indigo. Initially I tried to use maven plugin and could not succeed, so I am falling back to running on commandline mode.
C:\ modelcodegen> java -jar build/modelcodegen.jar Datamodel-V01.rdl src-gen
modelcodegen main entry point, args=[ Datamodel-V01.rdl, src-gen]
modelcodegen main is running

It works fine before creating one-jar on a standalone mode. I have also registered the package and resource factories as follows :
super.registerPackages(resourceSet);
if (!isInWorkspace(Rdl.RdlPackage.class)) {
resourceSet.getPackageRegistry().put(Rdl.RdlPackage.eINSTANCE.getNsURI(), Rdl.RdlPackage.eINSTANCE);
}
super.registerResourceFactories(resourceSet);
resourceSet.getResourceFactoryRegistry().getExtensionToFactoryMap().put("ecore", new EcoreResourceFactoryImpl());
resourceSet.getResourceFactoryRegistry().getContentTypeToFactoryMap().put(IAcceleoConstants.BINARY_CONTENT_TYPE, new EMtlBinaryResourceFactoryImpl());
resourceSet.getResourceFactoryRegistry().getContentTypeToFactoryMap().put(IAcceleoConstants.XMI_CONTENT_TYPE, new EMtlResourceFactoryImpl());
resourceSet.getResourceFactoryRegistry().getExtensionToFactoryMap().put("rdl", new RdlResourceFactoryImpl());
Any help in resolving either maven build or runnable jar would be highly appreciated.
Thanks,
Raj

Hello,
for me, I have resolved this problem by implementing an overriding createTemplateURI (defined in AbstractAcceleoGenerator.java) method. In this method, you need to return the path of your *.emtl file as following :
return URI.createURI(@Path + "/generate.emtl");
let me know if it works for you.
