I'm trying to set up a crawler, using Selenium under Java.
When I use ChromeDriver it works fine. However, I get into a whole new bunch of problems if I try to use a headless browser like PhantomJS.
this is where problems happen:
Capabilities caps = new DesiredCapabilities();
((DesiredCapabilities) caps).setJavascriptEnabled(true);
((DesiredCapabilities) caps).setCapability("takesScreenshot", false);
((DesiredCapabilities) caps).setCapability("locationContextEnabled", true);
((DesiredCapabilities) caps).setCapability("acceptSslCerts", true);
PhantomJSDriver jsDriver = new PhantomJSDriver(caps);
driver = jsDriver;
System.out.println("driver is set...");
driver.get("http://localhost/login"); //erorrs appears to be here
System.out.println("gonna wait for page loading...");
WebDriverWait wait = new WebDriverWait(driver, 40);
wait.until(ExpectedConditions.elementToBeClickable(By.id("emailAddr")));
WebElement element_email = driver.findElement(By.id("emailAddr"));
element_email.clear();
element_email.sendKeys("example@example.com");
WebElement element_password = driver.findElement(By.id("password"));
element_password.clear();
element_password.sendKeys("password");
WebElement element_login = driver.findElement(By.xpath("//input[@type=\"submit\"]"));
element_login.click();
the errors I get
driver is set...

gonna wait for page loading...
NOTE:
Program is still running but because of this error I was unable to login into the page.
How to solve this?
Is there any alternative?
EDIT one:
After following @Alfonso Presa I tried this:
String polyfill = "" +
" if (!Function.prototype.bind) {" +
" Function.prototype.bind = function(oThis) {" +
" if (typeof this !== 'function') {" +
" // closest thing possible to the ECMAScript 5" +
" // internal IsCallable function" +
" throw new TypeError('Function.prototype.bind - what is trying to be bound is not callable');" +
" }" +
"" +
" var aArgs = Array.prototype.slice.call(arguments, 1)," +
" fToBind = this," +
" fNOP = function() {}," +
" fBound = function() {" +
" return fToBind.apply(this instanceof fNOP && oThis" +
" ? this" +
" : oThis," +
" aArgs.concat(Array.prototype.slice.call(arguments)));" +
" };" +
"" +
" fNOP.prototype = this.prototype;" +
" fBound.prototype = new fNOP();" +
"" +
" return fBound;" +
" };" +
" }" ;
PhantomJSDriver jsDriver = new PhantomJSDriver(capabilities);
jsDriver.executeAsyncScript(polyfill);
driver = jsDriver;
unfortunately it throws this error now :
[ERROR - 2015-08-27T13:05:25.354Z] Session [482dc570-4cbc-11e5-960c-81dcdf4848bd] - page.onError - msg: SyntaxError: Unexpected token ')'

EDIT TWO:
after many trial, I install phantomJS version 1.9.8 and my original code just worked fine.
so overall:
- phantomJS version 1.9.0 had many bugs (just take it as many bugs)
- phantomJS version 2.0 had the above problem
- phantomJS version 1.9.8 worked just fine. I will try to investigate what the problem might be.
