String Xport = System.getProperty(“lmportal.xvfb.id”, “:1”); // setup firefox binary to start Xvfb
final File ffPath = new File(System.getProperty(“lmportal.deploy.firefox.path”, “/usr/bin/firefox”));
FirefoxBinary ffBinary = new FirefoxBinary(ffPath);
ffBinary.setEnvironmentProperty(“DISPLAY”, Xport);
