I eventually found some documentation about this library. A pdf given at Java 1 2008.
http://developers.sun.com/learning/javaoneonline/2008/pdf/TS-5711.pdf?cid=925556
But I can't find the source code. The PDF is a slide show and doesn't have all the details. Where can I find this source and other samples to help me get started?
TIA
its in the jmetest package
