How to solve the problem with Silenium on Windows 7?

Question

Windows

Began to explore Selenium features. The lesson described on the site www.tutorialspoint.com/selenium/index.htm was taken as the basis for the analysis of this thing. Previously, this resource helped me very well with the development of JSP. Installed JRE and JDK, Eclipse Mars. I started to deal with the material step by step and stalled on the Selenium - Remote Control section. I created the project and arranged the files according to the lesson I reviewed.

Started the seleniu server.
The launch went well.

I decided to see what firefox would show me when I went to the server page, the address of which was specified when it was launched, and received a 403 error message . I ran the

written test taken from the lesson and got the result.

I don’t know what to do next ... help experienced please.
On this, my study stalled because I don’t know where to dig.
