JBPM是一个扩展性很强的工作流系统，百分百用JAVA语言开发，持久层采用Hibernate实现，理论上说，只要Hibernate支持的数据库JBPM都支持。同时它还能被部署在任何一款JAVA应用服务器上。(JBPM is a highly expansible workflow system. It is developed in 100% by JAVA language, and Hibernate is implemented in persistence layer. In theory, as long as Hibernate supports database JBPM, it is supported. It can also be deployed on any of the JAVA application servers)
