Apache Tomcat 7.0.035 and IPv6 environment

[Geett Chanddra Singha]

Hi All,

I have a web application hosted on Apache Tomcat Version 7.0.035.
We are trying to make the web application run IPv6 environment.

Environment Details
Windows 2008 server machine, 64-bit OS
Java version: JRE 1.7.x

The home page of web application is not accessible using the IPv6 address.
The connectivity to windows server machine goes though IPv6 address.

Here is the Tomcat startup log details:

Hi All,
I have a web application hosted on Apache Tomcat Version 7.0.035.
We are trying to make the web application run IPv6 environment.
Environment Details
Windows 2008 server machine, 64-bit OS
Java version: JRE 1.7.x
The home page of web application is not accessible using the IPv6 address.
The connectivity to windows server machine goes though IPv6 address.
Mar 28, 2013 10:21:47 AM org.apache.catalina.core.AprLifecycleListener init
INFO: Loaded APR based Apache Tomcat Native library 1.1.24 using APR
version 1.4
.6.

APR connector cannot listen on both IPv4 and IPv6 addresses at the same time.
You have to choose one (with address attribute).

If you need both IPv4 and IPv6, configure 2 connectors.

It has been discussed previously. Search the archives.

Thanks Konstantin Kolinko!

It will be great help for me if you could provide steps to configure the
same or documents, where in I could get configuration steps.

Well, you could search the archives... that's what they are there for.
Or, you could read the online documentation:

https://tomcat.apache.org/tomcat-7.0-doc/config/http.html#Standard_Implementation

Look at the "address" attribute. On many systems, a single interface
has both IPv4 and IPv6 addresses, so you may or may not be able to do
this:

<Connector address="0.0.0.0" port="8080" />
<Connector address="::" port="8080" />

I'm not sure if Tomcat interprets the "address" value prior to handing
it off to APR... if so, you may have to use "0:0:0:0:0:0:0:0" for your
IPv6 address because IIRC Tomcat/JVM does not understand IPv6 shorthand.

Anyhow, if the above doesn't work (because port 8080 can only be bound
once per interface), you'll need to do something like this:

<Connector address="0.0.0.0" port="8080" />
<Connector address="::" port="8081" /><!-- note the different port -->
