Open a new browser from h:commandLink

Question

Dear All,
I wanted to have a h:commandlink (or commandbutton) to allow the user to open a new browser with a specified url. The value of the url is in the backing bean.
<h:commandLink ondblclick="javascript:window.open(theUrl)" binding="#{myBean.theUrl}">
<h:outputText value="click here" style="color:red;font-weight:bold;"/>
</h:commandLink>
Is this possible? How can I pass the myBean.theUrl value to the "theUrl" in the window.open()? Or are there any other ways to do this?
Any information would help.
Thank you very much in advance.

Pass it to the HttpServletResponse.
Basic example:public void downloadFile() {
    try {
        // Get file.
        BufferedInputStream input = new BufferedInputStream(new FileInputStream(getFilePath()));
        int contentLength = input.available();
        // Init servlet response.
        FacesContext context = FacesContext.getCurrentInstance();
        HttpServletResponse response = (HttpServletResponse) context.getExternalContext().getResponse();
        response.setContentType("application/octet-stream");
        response.setContentLength(contentLength);
        response.setHeader("Content-disposition", "inline; filename=\"" + getFileName() + "\"");
        // Replace "inline" by "attachment" to popup a save dialog.
        // Write file contents to response.
        while (contentLength-- > 0) {
            response.getOutputStream().write(input.read());
        // Finalize task.
        input.close();
        context.responseComplete();
    } catch (FileNotFoundException e) {
        // File not found. Do your error message thing.
    } catch (IOException e) {
        // I/O error. Do your error message thing.
}
