Hi,
I am trying to get my resource. The error is;

Exception in thread "main" org.eclipse.emf.common.util.BasicEList$BasicIndexOutOfBounds Exception: index=0, size=0

My code is about;

public class GetResource {
public static void main(String[] args) {
new DslmigrationStandaloneSetup().createInjectorAndDoEMFRegistra tion();
ResourceSet rs = new ResourceSetImpl();
Resource resource = rs.getResource(URI.createURI("./src/pree.mydsl"), true);
Model model = (Model) resource.getContents().get(0);
CompositeNode node = NodeUtil.getRootNode(model);
Iterable<AbstractNode> contents = NodeUtil.getAllContents(node);
StringBuffer text = new StringBuffer();
for (AbstractNode abstractNode : contents) {
if (abstractNode instanceof LeafNode)
text.append(((LeafNode)abstractNode).getText());
}
System.out.println(text);
}
}
Thanks

Hi,

it would help if you'd tell which of your lines causes the error but it seems like you somewhere access an element in a list of size zero which results in the EMF kind of ArrayOutOfBoundsException.

e.g. Model model = (Model) resource.getContents().get(0);
is you don't have anything in the model.
