Access static file from onModuleLoad() method

[AThinerCoin]

I'd like to access a static file, let's say config.xml from my onModuleLoad method. 

It says on this webpage, that config.xml should live in the public sibling dir of my .gwt.xml file, but I've tried that and onModuleLoad function still gives me the error below.

It also suggests that I add a line to the .gwt.xml file like   <public path='public'/>  but that isn't working for me either.

I've tried searching for an example, but I don't see one.

Thank you for your help!

Hi,

You should have the following :
/MyModule.gwt.xml
/public/config.xml

Then, you can access file with the URL : GWT.getModuleBaseURL() + "config.xml"

An other way to load content is to use a TextResource with ClientBundle ( see http://code.google.com/webtoolkit/doc/latest/DevGuideClientBundle.html#TextResource )

Thank you for your help.  This helped me get my source code to find my config.xml file.

For anyone else who has a similar problem, I also had to make a request for the file, then use the "getText" method, then I could read the file.  I could not just use the file based on the file's path.  See the example below.

        try {
            String fn = GWT.getModuleBaseURL() + "config.xml";
            RequestBuilder requestBuilder = new RequestBuilder(
                    RequestBuilder.GET, fn);
            try {
                requestBuilder.sendRequest(null, new RequestCallback() {
                    public void onError(Request request, Throwable exception) {
                        GWT.log("failed file reading", exception);
                    }

                    public void onResponseReceived(Request request,
                            Response response) {
                        result = response.getText();
                        Config graphConfig = new Config(result);
                        callToMethodThatUsesGraphConfig(graphConfig);
                    }
                });
            } catch (RequestException e) {
                GWT.log("failed file reading", e);
            }
        } catch (Exception e) {
            e.printStackTrace();
        }
    }
