HiWe are introducing some Activiti flow's into a well established Spring 4.11 project.A place where we are stumbling is autowiring of existing spring artificacts into java service tasksWe've a handful of java classes implementing JavaDelegate.

OK, first of all, i am assuming you are using activiti as a dependency in your Spring project,

How are you calling these service task Java delegates? Using an expression like ${mySpringBean.myMethod} ? Because the activiti:class won't work, it will do as advertised and create a instance of the class when needed.

Cause there is not much to it, except using expressions. Which is in the docs.

Hello Joram,

thank you for responding, yes activiti is a dependency and we are using expressions like ${mySpringBean.myMethod}. I'm not exactly sure what is happening, but I'll guess it is a spring configuration issue.

Our junits do wire activiti service task objects, but if the injected objects themselves need autowiring.. those autowired fields are always null.

Since posting the above I've learnt that all gets wired up correctly at deploy time (using a different context).
As I said not sure whats going on but have a workaround for the junits…

thanks again
john
