You missed setting the capabilities for the node.

Add this line and you should be fine after that.

req.setCapabilities(Arrays.asList(firefox));

Hey Krishnan,

I tried your's and Murali's solution for Chrome driver but getting error

org.openqa.grid.common.exception.GridConfigurationException: no server set to register to the hub

Can you please share working solution for multiple nodes ?

Thanks & Regards,
Vikram

[⇜Krishnan Mahadevan⇝]

Vikram,

The easiest way of doing this would be to invoke org.openqa.grid.selenium.GridLauncherV3#main by passing the required args (the ones that you would usually do when you are starting the hub/node from command prompt) through your main() method.

That way you don't have to write a lot of boiler plate code and still can get your hub or node to get spun off from within your code.

Thanks & Regards
Krishnan Mahadevan
