DefaultGlobalScopeProvider and "class path mechanism" [message #1388436] Thu, 26 June 2014 12:54 Go to next message

Hello,

I would like to be able to resolve a reference from a qualified name based on the Java class path. Assuming that I've one file 'F1.myDsl' (stored in the package com.example.app1) referring to another file 'F2.myDSL' (stored in the package com.example.app2) :

myApp F1 {
ref com.example.app2.F2
}

The linking works fine when I load manually F2 and F1 in the resourceSet, but when I load only F1 (expecting that DefaultGlobalScopeProvider would find F2) the linking fail.

Can anybody tell me how to enable the the "class path mechanism"?

Regards,
Grégoire

HI,

am not sure if i get your problem. and i dont know such a possibity, but the following works for me

Model:
	greetings+=Greeting*;
	
Greeting:
	'Hello' name=ID ('from' from=[Greeting]) '!';


public class Main {
	
	public static void main(String[] args) throws IOException {
		Reader reader = new Reader();
		reader.setUseJavaClassPath(true);
		reader.addRegister(new MyDslStandaloneSetup());
		reader.addPath("models");
		SlotEntry outputSlot = new SlotEntry();
		outputSlot.setType("Greeting");
		reader.addLoad(outputSlot);
		WorkflowContextImpl ctx = new WorkflowContextImpl();
		reader.invoke(ctx);
		for(Greeting g : (List<Greeting>)ctx.get("model")) {
			System.out.println(g.getName() + " " + g.getFrom());
		}

		
	}

}
