Java Development Tools

Using JDeveloper 12.1.3

I want to open up multiple URLs based on a selection in a (multiselect) ADF-table

I am looping over the selection, creating a URL and the calling openUrl (url) as shown below

    private void openUrl(String url) {
        try {
            System.out.println(url);
            FacesContext.getCurrentInstance().getExternalContext().redirect(url);            
        } catch (Exception e) {
            System.out.println(e.getStackTrace());
        }


    }

This will result in an error or only opening one of the links.
