Webdriver Grid setup

[nurav]

Hi Tarun,

I want to run my scripts using grid execution.Steps done till now
 - Navigate to the folder where i have placed selenium-server-standalone-2.21.0.jar thru CMD prompt
 - Ran java -jar selenium-server-standalone-2.14.0.jar -role node  -hub http://localhost:4444/grid/register 

But here i am getting an errors
WARNING: error getting the parameters from the hub. The node may end up with wrong timeouts.A JSONObject text must begin with '{' at character 1
Registering the node to hub :http://localhost:-1/grid/register
couldn't register this node : Error sending the registration request.

My Machine itself is a server

App URL: localhost
port : 80

Can you please let me know the exact step to configure the grid execution.

Thanks,
Varun

Hi Nurav,

You mentioned -  selenium-server-standalone-2.21.0.jar but you use 2.14.0 when starting node -

< java -jar selenium-server-standalone-2.14.0.jar -role node  -hub http://localhost:4444/grid/register >

Do you see discrepancy?

Hey Tarun ..sorry for confusing...

I used this....java -jar selenium_2.21.jar -role node  -hub http://localhost/grid/register

Let us ignore this warning for time being -

WARNING: error getting the parameters from the hub. The node may end up with wrong timeouts.A JSONObject text must begin with '{' at character 1 

Coming to -

java -jar selenium-server-standalone-2.21.jar -role node  -hub http://localhost:4444/grid/register 

Are you running hub and node on same machine, if not then you need to give ip address of hub when starting node, as you eventually get this error -

12:06:13.734 INFO - couldn't register this node : Error sending the registration request. 
12:06:18.734 INFO - couldn't register this node : hub down or not responding. 
12:06:23.765 INFO - couldn't register this node : hub down or not responding.

Was this issue resolved? I'm facing the exact same issue while trying to register node to hub runnning on the same machine. Note that I've verifed server to be up & running on the browser.

Any thoughts/clues?
