开源世界的版本问题，永远是入门者的噩梦，简单记录一些资料。 目前jbpm主要有3 4 5三个版本，用5的目前很少，用4的也不多，主要是用的3 然后3.1和3.2的界面不同，3.1用jbpm而3.2用jbpm-console，3.2的功能多些支持用户管理而3.1的界面很好。 主要用3.1.4-startkit和3.2.3-startkit。 开发环境建议 1. jbpm-starters-kit-3.1.4.zip 下载地址： http://nchc.dl.sourceforge.net/project/jbpm/jBPM%203/jbpm-3.1.4/jbpm-starters-kit-3.1.4.zip 2.
