Bossa is a workflow engine written in Java. The engine is very fast and lightweight, uses a very expressive Petri net notation to define workflows, does not require a RDBMS, and is very simple to use and integrate with Java applications. Actually, it was designed to be embedded. Therefore, Bossa is organized as a library to be used by server-side applications (especially Web-oriented ones) that need workflow services.
The Bright Side Framework provides ready-to-use, high-level J2EE components which will help you quickly build business J2EE applications accessed by rich Java/Swing clients on HTTP. The components are loosely coupled, which allows you to pick only the one you need. The Remoting transparently encapsulates EJB calls inside HTTP. The List Of Values provides nice features for the reference data of all business applications. The Smart Value Object tracks the client modifications and manages the optimistic concurrency during client/server communication. The Remote Iterator allows a rich client to fetch the results of a SQL statement, block by block.
BtFree is a library for creating client-server applications that communicate over a Bluetooth connection. You can use it in your MIDP application or in a Java application that uses an implementation of JSR82. It allows you to create applications with client-server interaction easily, avoiding the need to know JSR82 and the problems related.
