Tomcat Not Starting Through Eclipse (Timeout)

Question

I am trying to run Tomcat through Eclipse. This is something that I have done for the past several years. It was working yesterday and now it is not. The error I get is

Answer 1

I solve this trouble adding

127.0.0.1 localhost

to hosts localdns file (C:\Windows\System32\drivers\etc\hosts), seems that this problem is due to a ipv6 on localhost name.

To understand if this is the problem try to ping localhost and see if it is solved ad ipv4 or ipv6.
