Unicon has recently released to opensource (under the GPL) source code derived from their Academus product.
Academus 2.1 was codenamed "toro" in development, and so the opensource derivatives of it are collectively called "OpenToro".
This includes
toro-channels
A collection of channels and plugins for uPortal, including a polished ALM theme, a performance-enhanced local group store implementation, enhancements to the Permissions Manager UI usability, a Collaborative Groupware course management system, a notes channel, a bookmarks channel, and a calendar channel.
toro-portlets
JSR-168 portlets implemented using the Unicon-developed-and-now-opensourced-in-this-project Warlock application development framework, including a Gateway Single-Sign-On store-and-forward credentials proxying portlet, a pluggable filesharing Briefcase portlet, a Notifications portlet, and a Permissions Management meta-portlet for administering the rest.
toro-resource-pool
A JDBC connection pool predating the modern constellation of opensource pools, implementing a great deal of logging and diagnostics.
toro-sdk
Java utilities used in the other projects.
