Activemq IPV6 Client Connection (Java and C++)

[Oscar Pernas]

Hi all,

Im trying to use ActiveMQ with IPV6 but Im running into some problems. I'm
in debian linux, and seems that ActiveMQ(5.5.1) is up and listening IPV6.

tcp6 0 0 :::61616 :::* LISTEN 24671/java

I can make a ping and a telnet to ::1 61616 and all seems that works fine.

Now Im trying to connect two clients (one in Java and one in C++).

-Java client: If I set the uri tcp://[::1]:61616, connection is stablished,
but if I add the failover transport (failover://(tcp://[::1]:61616)), I can
see an Invalid broker URI exception. Its not compatible, or there is
another way to use failover with IPV6?

- C++ Client: Im setting the same URI that it works in Java
(tcp://[::1]:61616) but doesnt work and I get "Resource temporarily
unavailable". Any idea of what coulde be reason? I tested too with a
connection string like this: ""tcp://[fe80::XXX:XXXX:XXXX:XXXX]:61616" and
I'm receiving this error "the requested name is valid and found in
database, but doesnt have the correct data that is trying to resolve".


Any Idea?


thanks in advance

can you post the failover uri from the java case and the exception?

Working up a unit test for this and creating an issue would be helpful,
there are already some URI parsing tests in svn.

The C++ client doesn't have any support for IPV6 yet, we welcome any
contributions you'd like to make in this area.

As I encountered this recently, I figured I would post the solution here, in
case someone else encounters it someday.

The problem is Java's URI parser (not ActiveMQ) will not accept the left
bracket in the IPv6 address in "failover://(tcp://[::1]:61616)", where it
WILL accept the corresponding IPv4 structure
"failover://(tcp://127.0.0.1:61616)" and IPv6 without failover
"tcp://[::1]:61616".

The solution to this is to exclude the "//" from the failover.
"failover:(tcp://[::1]:61616)" is accepted by the Java URI parser, and will
function correctly.

Thanks Matthew for circling back with the solution to this!
