Cannot open Selenium Jar file from CMD. Path or ClassPath issue?

I encountered the same issue. The solution is that the naming convention matters. if you have a selenium server standalone.jar file, you can rename it first to make it look simple(example abc.jar).

1) If the jar file in your system is encountered with the .jar extension, then after renaming, give the .jar extension.(eg abc.jar)

2) If the jar file in your system is not having the .jar extension, then after renaming, dont provide the .jar extension(eg abc)

3)Start the hub now: java -jar abc.jar -role hub

Unable to access the jarfile is considered as Common Error. This error can occur when starting up either a hub or node. This means Java cannot find the selenium-server jar file. Either run the command from the directory where the selenium-server-XXXX.jar file is stored, or specify an explicit path to the jar.

Your filename must be wrong. Check whether you have a file named -selenium-server-standalone-2.14.0.jar. Chances are you won't be. :)
