Re: Error with FirefoxBinary in RemoteWebDriver

[Mike Riley]

The error being reported says you were trying to cast a java.util.HashMap object to a String.  So the raw object is a HashMap.

Is it possible that your Firefox is not installed in a standard location, so it can't find it?

Hi,

I am using RemoteWebDriver for some months and everything is working fine. But now I am triying to modify a property of FirefoxBinary. I am doing the following:

DesiredCapabilities capabilities = new DesiredCapabilities();
...
FirefoxBinary fb = new FirefoxBinary();
fb.setTimeout(java.util.concurrent.TimeUnit.SECONDS.toMillis(90));
capabilities.setCapability(FirefoxDriver.BINARY, fb);
driver = new RemoteWebDriver(new URL("http://localhost:4444/wd/hub"),capabilities);

It is not working. The problem seems to be in FirefoxDriver class where try to get the FirefoxBinary. It is doing this:

 Object raw = capabilities.getCapability(BINARY);
      if (raw instanceof FirefoxBinary) {
        return (FirefoxBinary) raw;
      }
      File file = new File((String) raw);

But the instanceof is not returning TRUE and function tries to create a new file from object doing a cast to String. This is the error!!!!
What can I do to solve it? Any idea?

Thanks in advanced for your support.

Here you can find the trace log
