Subject Re: Activemq webconsole for multiple brocker
Date Wed, 14 Aug 2013 15:24:26 GMT
Great blog post Christian, keep up the great work! Would be good to
show the new move/delete/replay-of-DLQ messages too thats available in
5.9.x :)

I've just cut 1.2-M5 of hawtio which fixes those issues (thanks for
figuring them out  - especially the commons-codec issue!).

I also fixed this one too:
https://github.com/hawtio/hawtio/issues/472
to report more gracefully if we try to connect to a remote JVM and
can't due to an issue such as a wrong path, host name or port etc.

Finally 1.2-M5 has a new executable jar; so its super easy to get
started running hawtio; no need to muck about with tomcat/jetty/wars,
you can just download the executable jar and you're on your way to
hawtness.
http://hawt.io/getstarted/index.html

So hopefully we should be close to getting rid of these
remote-connection gremlins now.

Thanks for all your help!
