I’m onto the Gentoo train
With the struts-1.3.5 ebuild, nichoj offered me access to the Gentoo java overlay.
An overlay is an alternative branch of the official portage tree, where experimental ebuilds are made available to testers and people in a hurry to use an application or have a library.
Of course, “happy” is not a word worth describing my pride.
There are still a LOT of things I have to learn. But I got the patience: hope my team mates have enough of it, too.
