Now , I am learning activiti . But there is not source code package to download in the download page. Is it the activiti a opensource project? Where can I found the source code of activiti?
No, activiti is not an opensource project. Only people that are very good are allowed to use it, and only after a thorough and painfull initiation (you have to get the belgian nationality or learn to drink their beer) you are allowed to develop on activiti.
