"Web-KeePass is web based Java port of the KeePass project. A free, easy to use password manager which helps you to manage your passwords in a secure way." It depends on the jrivet framework as well http://www.jrivet.com/. And come bundled with various stuff, but the source code is in the release. This may be hideous or no big deal for Java ebuild developers. Reproducible: Always Steps to Reproduce: Try to install webkeypass on gentoo. It depends on jrivet, http://www.jrivet.com/, and comes bundled with tomcat. The release actually has a source code directory that lets you run it on other servlet platforms.
6 years later, the homepage died. There's this page: http://sourceforge.net/projects/webkeepass/files/webkeepass_archive/ which shows the project is not very active and kinda old now (last release is 4 years old). Not sure if it's worth the effort. If you do need this ebuild, reopen.
