How do I create a Groovy script to integrate with Selenium?

I am currently doing a proof of concept for automated testing of SOAP and REST services and in some of the test steps I need to navigate to a URL and perform some actions so I knew I could create a Groozy script and utilise Selenium.  So I read the documentation here:

http://readyapi.smartbear.com/features/integration/selenium/introduction

and followed everything to the letter buy I am not having any success.  I made some modifications to try the different drivers and log errors so as it stands my code is as follows:

import org.openqa.selenium.By;
import org.openqa.selenium.WebDriver;
import org.openqa.selenium.WebElement;
import org.openqa.selenium.firefox.FirefoxDriver;
import org.openqa.selenium.chrome.ChromeDriver;
import org.openqa.selenium.ie.InternetExplorerDriver;

try {
    log.info("create FirefoxDriver object");
    WebDriver driver;
    driver = new FirefoxDriver();
    driver.get("http://www.google.com");
} catch (Exception e) {
    log.error(e.message);
    driver = null;
}

try {
    log.info("create ChromeDriver object");
    WebDriver driver;
    //System.setProperty("webdriver.chrome.driver", "C:\\DevTools\\Selenium\\chromedriver.exe");
    driver = new ChromeDriver();
    driver.get("http://www.google.com");
} catch (Exception e) {
    log.error(e.message);
    driver = null;
}

try {    
    log.info("create InternetExplorerDriver object");
    WebDriver driver;
    //System.setProperty("webdriver.ie.driver", "C:\\DevTools\\Selenium\\IEDriverServer.exe");    
    driver = new InternetExplorerDriver();
    driver.get("http://www.google.com");   
} catch (Exception e) {
    log.error(e.message);
    driver = null;
}

I have commented out the System.setProperty lines because I have added the location to the enviroment variable PATH.

For the Firefox driver I get an error which includes:

<p>The following error was encountered while trying to retrieve the URL: <a href="http://127.0.0.1:7055/hub/session">http://127.0.0.1:7055/hub/session</a></p>

For Chrome I get the following:

Tue Nov 03 13:52:57 GMT 2015:ERROR:Could not start a new session. Possible causes are invalid address of the remote server or browser start-up failure.
Build info: version: '2.48.2', revision: '41bccdd', time: '2015-10-09 19:55:52'
System info: host: '', ip: '', os.name: 'Windows 7', os.arch: 'amd64', os.version: '6.1', java.version: '1.8.0_65'
Driver info: driver.version: ChromeDriver

For Internet Explorer I get the following:

Tue Nov 03 13:53:17 GMT 2015:ERROR:Could not start a new session. Possible causes are invalid address of the remote server or browser start-up failure.
Build info: version: '2.48.2', revision: '41bccdd', time: '2015-10-09 19:55:52'
System info: host: '', ip: '', os.name: 'Windows 7', os.arch: 'amd64', os.version: '6.1', java.version: '1.8.0_65'
Driver info: driver.version: InternetExplorerDriver

I have searched online for possible solutions but everything I have seen doesn't work. Can anyone offer any advice on how to get Selenium working with Ready! API?
