UDDI4J is a Java class library that provides an API to interact with a UDDI (Universal Description, Discovery and Integration) registry. (Yet another dependency of jboss...)
Created attachment 59811 [details] uddi4j-2.0.3.ebuild The only problem that I encountered was that when using jikes, activation.jar needs to be available. I didn't encounter this when not using jikes with blackdown, so some testing will be needed with other JDKs.
Pretty much all Gentoo devs involved in this bug retired. 2005? Does someone want this ebuild to go into the tree nonetheless? You know the drill: comment or close. According to HOMEPAGE, last update dates back to 2013.
This project is very old and it makes very little sense to package it in 2016. Closing.
