PhantomjsDriver not working on both Windows and Li

I have an application that uses Selenium Webdriver to get some information from a site. It works fine with FirefoxDriver and ChromeDriver, but when I tried to switch to PhantomJSDriver, I encountered some difficulties.

On a Windows machine , it starts normally, then immediately begins spitting out the following lines over and over again:

Jan 05, 2014 7:28:43 PM org.apache.http.impl.client.DefaultRequestDirector tryEx ecute INFO: I/O exception (org.apache.http.NoHttpResponseException) caught when processing request: The target server failed to respond

This is repeated probably several hundred times for about 10 minutes until it finally loads the page; sometimes it doesn't even manage to load it at all.

On a Linux machine, it tries to start, then returns the following:

Exception in thread "thread1" org.openqa.selenium.remote.UnreachableBrowserException: Could not start a new session. Possible causes are invalid address of the remote server or browser start-up failure.

What am I doing wrong? I've read a lot about how Phantomjs is so much faster than the other drivers, and would really like to use it, but if it takes 10 minutes to load each page, that's obviously not feasible.

I am running Selenium WebDriver version 2.38.0 and Phantomjs version 1.9.2.

Thank you very much in advance, bsg

EDIT Just to clarify, I don't think this has anything to do with my code; the errors on Linux are being thrown on the line where I try to start the PhantomJS driver, below.

   DesiredCapabilities caps = new DesiredCapabilities();
    caps.setJavascriptEnabled(true);                       
    caps.setCapability(
        PhantomJSDriverService.PHANTOMJS_EXECUTABLE_PATH_PROPERTY,
        phantombinary//"/home/p/phantomjs-1.9.2-linux-x86_64/bin/phantomjs"
    );

    // Launch driver (will take care and ownership of the phantomjs process)
     WebDriver driver = new PhantomJSDriver(caps);
    System.out.println("starting driver");

回答1:

If it is still not working for you on Linux, try below piece of code, it is working for me on Mac.

capabilities.setCapability("phantomjs.binary.path", "path of phantom binary/phantomjs")

回答2:

org.openqa.selenium.remote.UnreachableBrowserException clearly something to do with Phantom. On Windows ensure Phantom is running (Set Environment variable and add PATH) Check that Remote Machine hub address is correct and you should be able to run phantomjs.

Note: Selenium Server must be running on the desired remote machine.

DesiredCapabilities phantomBeast = DesiredCapabilities.phantomjs();

try {
    webDriverInstance = new RemoteWebDriver(new URL(hubUrl), phantomBeast);
} catch (Exception e) {
    //Do something 
}
