Img works in dev mode but not production

Technical Q&A
1

Hi,

I have an Img object that works fine in dev mode (tested in FF), but not in production. It doesn’t pick up the image, and is just blank.

The code is:

        Tab tTab4 = new Tab("Alerts");
        Img tImg4 = new Img("/images/alerts.png", 647, 763);
        tTab4.setPane(tImg4);

I’ve checked and re-checked the war file. Appending “/images/alerts.png” to the app name, in place of the HTML file, in the browser brings up the image.

It is the SGWT build from Feb. 17th. Any help would be appreciated.

Thanks

I figured it out - it’s the old context root issue (required in prod, not required in dev). Just have to figure out which it is dynamically with a piece of code like the following:

String queryString = Window.Location.getParameter("gwt.codesvr");
        if (queryString != null && !queryString.equals("")) {
            // Dev Mode
            return "";
        } else {
            String path = Window.Location.getPath();
            int slashPos = path.substring(1).indexOf("/");
            return path.substring(0, slashPos + 1);
        }
