I need help automating test cases headless with Selenium using Java. Despite trying methods described in this Stack Overflow post, I've run into an issue where simply clicking elements is not working with PhantomJS. Instead, a NullPointerException is being thrown.
All the solutions I have come across so far only address the problem in JavaScript.
Does anyone know of a solution that works with Java?
Thank you and best regards,

To enhance my understanding of working with PhantomJS, I decided to experiment with a simple Google search today. Here are the steps I took:
Here is the code I used:
System.setProperty("phantomjs.binary.path", "webdriver/phantomjs.exe");
WebDriver driver = new PhantomJSDriver();
driver.get("http://google.com");
Thread.sleep(20000);
File file = ((TakesScreenshot)driver).getScreenshotAs(OutputType.FILE);
FileCopyUtils.copy(file, new File("C:/Users/username/Desktop/screenshot.jpg"));
Actions a = new Actions(driver);
a.moveToElement(driver.findElement(By.xpath("//*[@id=\"lst-ib\"]"))).click().perform();
a.sendKeys("Hello").perform();
I tried clicking on the textfield and entering "Hello," but encountered an error - "NoSuchElementException," not "NullPointerException."
org.openqa.selenium.NoSuchElementException: {"errorMessage":"Unable to find element with xpath '//[@id=\"lst-ib\"]'","request":{"headers":{"Accept-Encoding":"gzip,deflate","Connection":"Keep-Alive","Content-Length":"47","Content-Type":"application/json; charset=utf-8","Host":"localhost:39266","User-Agent":"Apache-HttpClient/4.5.1 (Java/1.8.0_66)"},"httpVersion":"1.1","method":"POST","post":"{\"using\":\"xpath\",\"value\":\"//[@id=\\"lst-ib\\"]\"}","url":"/element","urlParsed":{"anchor":"","query":"","file":"element","directory":"/","path":"/element","relative":"/element","port":"","host":"","password":"","user":"","userInfo":"","authority":"","protocol":"","source":"/element","queryKey":{},"chunks":["element"]},"urlOriginal":"/session/1fae7fb0-3651-11e7-a707-9fe5bd25a173/element"}} Command duration or timeout: 303 milliseconds For documentation on this error, please visit: at [error details]...
