IPv4 is enabled on the server. The IPv6 stack is also enabled, and
necessarily configured as,
grep bindv6only /etc/sysctl.conf
net.ipv6.bindv6only = 1
I want Tomcat listening on the IPv4 localhost @ 127.0.0.1.
So, reading here -
http://tomcat.10.n6.nabble.com/Tomcat-uses-IPv6-td2164369.html#a2164371
- and elsewhere, I set
vi /etc/tomcat/tomcat.conf
...
JAVA_OPTS="Djava.net.preferIPv4Stack=true
-Djava.net.preferIPv4Addresses=true"
CATALINA_OPTS="Djava.net.preferIPv4Stack=true
-Djava.net.preferIPv4Addresses=true"
...
now, @ tomcat start,
ps ax | grep tomcat
6530 ? Sl 0:03 /etc/alternatives/jre/bin/java
-Djava.net.preferIPv4Stack=true
-Djava.net.preferIPv4Addresses=true

but, Tomcat still listens only on IPv6
netstat -pan --tcp | grep 8080
tcp 0 0 :::8080 :::*

and is unavailable/unreachable @ 127.0.0.1

has the method for getting Tomcat to listen only @ IPv4 changed for v7?
