Re: GWT + EMF + JSON

I know nothing about EMF,  or emf-json, but it seems to me that you need to do it this way:

https://emfjson.github.io/projects/gwt/latest/

(using emfjson-gwt)

Hi all,

I am using GWT with EMF and I want write files on client side containing description of some EMF object with the JSON format. For this purpose I use EMFJson tool  (https://emfjson.github.io/) with the following code but I can't write the file,. Have you an idea?

Here is the code:

        // As of here we preparing to save the model content
        ResourceSet resSet = new ResourceSetImpl();
        // Register the XMI resource factory for the * extension
        resSet.getPackageRegistry()
        .put(EcorePackage.eNS_URI,EcorePackage.eINSTANCE);

        resSet.getResourceFactoryRegistry()
        .getExtensionToFactoryMap()
        .put("*", new JsonResourceFactory());

        // Obtain a new resource set
       
        resSet.getURIConverter().getURIHandlers().add(new LocalStorageHandler());

        // create a resource
        URI uri = URI.createURI("file:///" + "D:/Spottest.json");
        GWT.log(uri.toString());
        Resource resource = resSet.createResource(uri);
        // Get the first model element and cast it to the right type,
        // everything is hierarchical included in this first node
        resource.getContents().add(custom);

        // now save the content.
        // resource.save(Collections.EMPTY_MAP);
        try {
            resource.save(Collections.EMPTY_MAP);
        } catch (Exception e) {
            GWT.log("Pb saved " + e.getMessage());
        }

Thanks a lot for your help.

Antonio
