JBlooming is a framework for building views of Java Web applications. It empowers JSP-based views with tools to easily integrate o-o modeling, and provides a large set of ready components.

Redstone Prevalent Storage is minimalistic prevalent storage for Java SE 5.0 that replaces the need for JDBC and an RDBMS for small and mid-sized applications. The library is comprised of an intentionally small set of concise interfaces and classes, and can be suitable for many types of applications where the data storage does not necessarily require an RDBMS. The library is heavily influenced by Prevayler and the Prevayler team (who should receive all credit).
