Today I started getting this weird looking exception while launching tomcat.
[sourcecode language=”java”]

I googled around and most answers were pointing towards Port is already being used, which definitely wasn’t the issue in my case, anyways after spending few hours I figured out my main issue was that my IPV4 address changed. Although I never updated my server.xml to change localhost to any specific IP address but yet I started getting this error.
The actual cause of this issue was my host file present at WINDOWS_INSTALLTION/windows/System32/drivers/etc, where in which my old IP address was mapped against localhost like below:
[sourcecode langugage=”txt” highlight=”2″]
127.0.0.1 localhost
192.168.XXX.XX localhost
[/sourcecode]
This second line was the main culprit, there are two ways of solving this:
- Remove 192.168.XXX.XX localhost line completely from host file
- Replace old IP with new IP in your host file i.e instead of 192.168.XXX.XX localhost change it to 192.168.XXX.YY localhost
Hope this helps!
