openlayers load local gml

Question

I'm trying to load a simple gml file with openlayers, but it doesn't load.

Pretty sure it's a simple issue, but I figure out what's wrong.

Thanks in advance, Pedro

            var meu = new OpenLayers.Layer.Vector("States", {
            protocol: new OpenLayers.Protocol.HTTP({
                url: "teste.GML",
                format: new OpenLayers.Format.GML()
            }),
            strategies: [new OpenLayers.Strategy.Fixed()],
        });

        map.addLayer(meu)

Tried firefox and safari in mac os and firefox in linux

If you mean that you want to load a file that is stored in the file system of your computer, the short answer is that you cannot. From the Wikipedia:

JavaScript and the DOM provide the potential for malicious authors to deliver scripts to run on a client computer via the web. Browser authors contain this risk using two restrictions. First, scripts run in a sandbox in which they can only perform web-related actions, not general-purpose programming tasks like creating files. Second, scripts are constrained by the same origin policy: scripts from one web site do not have access to information such as usernames, passwords, or cookies sent to another site. Most JavaScript-related security bugs are breaches of either the same origin policy or the sandbox. (http://goo.gl/iqW7n)
