About:
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.

Release focus: Major feature enhancements

Changes:
This release adds a historian to track events that happened in the engine. It is possible to query events by time range and filter them by case type, case, and resource. The transient Bossa was improved: it is possible to embed it deterministically with relation to time using time sources.

[»] Persistence
by HR - Jan 21st 2004 00:12:51

It would be nice if there was a choice of persistence provider in Bossa. Prevayler is a good basic system giving almost lossless persistence, but it does not scale well because it relies on all the persisted objects being in memory at the same time.
Have a look at Turbine Torque from Apache Jakarta. Use Prevayler if you must to persist the working data and Torque to archive the rest.
Better scalability will give Bossa a greater chance of being used in an enterprise context.
