JPAUnit Release V0.1 - Mandela Day Release 2015

JPAUnit is a Java library for assisting with unit testing your JPA code. It  facilitates the initialisation of a database to a known state before commencing units test in Java. It leverages the mapping already done in your application's model that maps Java POJOs to database tables to insert data, defined in XML files into the target database.

JPAUnit leverages the database abstraction layer already created by JPA data providers to allow tests to target any vendor database that is compatible with your JPA provider.

IPv6 - Set Up An IPv6 LAN with Linux

Setting up an IPv6 LAN with Linux? Ever wondered how to do that? For years we have heard the dire predictions about the impending doom of IPv4 and the imminent arrival of IPv6.

So far the former strategy has served many sys admins well and proved to be an effective strategy .
