Activiti in OSGI - unresolved dependencies

[marcelwolf]

Hey Everybody!

I try to get Activiti running in Karaf.


Here is my BluePrint:

It starts the Bundle and says:

 Bundle jobs-bpmn/1.0.0 is waiting for dependencies [(objectClass=org.activiti.engine.ProcessEngine), (objectClass=org.activiti.engine.ProcessEngine), (objectClass=org.activiti.engine.HistoryService), (objectClass=org.activiti.engine.ProcessEngine)]

and gets timeout after some time:

what did i do wrong?


Thanks a lot!

Hi Marcel,
I want to reproduce the issue but I would like to have some more details about your setup:
Activiti version, Karaf version … (and any other details you consider important to mention)
