XEO (eXtensible Enterprise Objects) is an agile development framework designed for creating Web applications built around Object Oriented concepts and Model Driven Development with Java. You model business entities (including their attributes and behavior) as XEO Models which are then processed by the framework's "Builder". This produces the application's supporting structures such as database tables (to persist data) and Java classes (providing object-relational mapping and behavior). Development is supported by an Eclipse plugin called XEOStudio.
Java distributed framework is a framework for distributed grid and / or volunteer computing. It's divided into a server and client library. You can create new or implement it into existing applications in no time; you don't need knowledge about network connections, sockets, etc. The Framework does almost everything automatically. It provides secure automatic client <-> server communications, unique IDs, automatic resending of jobs to new clients if needed, user stats, and much more. The client framework supports the detection of the computer's user state (idling, away, online, etc.). It also offers many other useful features and helpers for developing a distributed client application.
