Bigbross Bossa 介绍
速度非常快、轻量级的引擎，使用富有表达能力的Petri网定义工作流，不要求关系数据库，使用简单，能和Java应用集成。事实上，它是按嵌入式设计的。
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 to 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. We plan, in the future, to implement a
shell over the current library to offer workflow services as a stand alone
server.
