Hi all,

I'm experiencing issues when trying to compile an ATL file in .asm with
the
ATL 3.0 api. I'm trying to do this like this:

meo2atl.execute(mapping, model, ontology);
String content = meo2atl.serialize();

AtlCompiler.compile(
new ByteArrayInputStream(content.getBytes()),
fileName
);

meo2atl is a call to an high order transformation that produces an ATL
model.
I serialize this ATL file by calling the method serialize and put it in
content. But when trying to call the AtlCompiler i got the following
errors. Can someone tell me where i'm wrong?

thanks.

java.lang.RuntimeException: Eclipse platform extension registry not found.
Dynamic repository lookup does not work outside Eclipse.

Hi Guillaume,

I guess you don't launch your application as a plugin, so the extension
registry (which usually loads model handlers) doesn't work.
In your case you must first register the AtlEMFModelHandler (which is
used by the AtlParser):

AtlModelHandler.registerDefaultHandler("EMF", new AtlEMFModelHandler());
// then compile etc...

Then the model handler will be directly available and the "getDefault"
method will bypass the extension lookup.

Best Regards,

William
