Running argoUML, fixing hostname
When attempting to run ArgoUML under my custom install of Debian Lenny, it died on startup with the following: "ERROR: unable to get localhost information. java.net.UnknownHostException (...)" solution: check the output of the command hostname , add a line corresponding to that name to the file /etc/hosts Anyway, it might be a great piece of software, but I didn't have much luck with the functionality I needed. Namely, my simple collaboration diagram got its indexes all mixed up.
