Naked without eclipse

I recently had to make a few changes to a java project. The computer at my disposal, Gentoo Linux AMD64 machine, did not have eclipse installed. So I turned to my reliable editor/IDE, i.e. Emacs. Considering that Emacs was my IDE for several years in the past, I still felt astonishingly naked without Eclipse. Only under circumstances where a tool is withdrawn that one realizes how much comfort it brings and that you can't live without it.
