TinyRadius is a simple, small and fast Java Radius library capable of sending and receiving Radius packets of all types. It is released under the terms of the LGPL.
My fork of
TinyRadius Java Library is at github.com/davipt/TinyRadius.
The fork contains performance optimizations for high volume multi-threaded applications, in particular some fixes for vendor specific radius attributes.
The original site for TinyRadius is at tinyradius.sourceforge.net and developed by Matthias Wuttke.
