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!
