Could anyone give me some hint on how can I open a url on external browser using a relative path from a customized Welcome page plugin?

The following code is an example of what I have so far in "intro.xml", which is working and displaying the html file OK for Linux but it doesn't work for Windows.

<link
label="Documentation"
url="http://org.eclipse.ui.intro/openBrowser?url=file:../documentation/index.html"
id="link-img-documentation"
style-id="content-link">
<text>Read documentation.</text>
</link>

I found a workaround, by using "http://org.eclipse.ui.intro/runAction" and create a class that implements "IIntroAction"

First step: Add a class that implements IIntroAction" :

public class OpenFileInBrowser implements IIntroAction {
    @Override
    public void run(IIntroSite site, Properties params) {
        
        if (params.containsKey("filePath") ){
            String filePath = params.getProperty("filePath");
            String workingDir = System.getProperty("user.dir");
            String urlString = "file://" + workingDir + File.separator + filePath;
            
            try {
                IWorkbenchBrowserSupport browserSupport = PlatformUI.getWorkbench().getBrowserSupport();
                IWebBrowser browser = browserSupport.getExternalBrowser();
                URL url = new URL(urlString);
                browser.openURL(url);
            } catch (Exception e) {
            }   
        }   
    }
}

Second step: Update the url in the link tag as follows:

 url="http://org.eclipse.ui.intro/runAction?pluginId=x.y.z&amp;class=x.y.z.OpenFileInBrowser&amp;filePath=../documentation/index.html"
