I set up Activiti 5.13 in Tomcat 7. Everything works great. I can deploy process definitions just fine. So I copy the Tomcat folder (w/ Activiti) and handed to him. He installed database on his machine w/ the same user/password like mine. He's able to view Activiti-Explorer. However, when he tries to upload a process definition, Activiti throws this error:

It's not wrong with the process definition because I can upload it on my machine just fine. I don't know if there is anything that need to be configured outside the Tomcat folder (other than database) that I forgot to tell him?
Please help. Thanks,
Tan
