Java Ultra-Lite Persistence is an RDBMS-independent object-relational library. It features inheritance, many classes per table, many tables per class, optimistic concurrency, and simple mappings, etc.
Small bugs were fixed and optimizations were made. The distribution now includes projects for NetBeans including source, jars, and examples. The examples are described in EXAMPLES-README.txt.
