delegateExpression failed to find Spring managed bean

[chamindakiriwen]

Hi Friends,

I'm trying to test a very simple process with one sevice task, and I want to manage Java Delegate class as a spring managed bean. I've followed all the steps described in Activiti User Guide, but still I'm getting "Bean Not Found" error. Highly appriciate, if anybody can help me figure out my missing point. I have highlighted the log with my findings.

The process engine should be a SpringProcessEngineConfiguration. I don't see (except where referenced in osgi:… id="processEngine") where the process engine is configured and what its class is

[chamindakiriwen]

Thanks for giving me a direction, In our development environment, Activiti engine is configured in servicemix, and all we use it. As a work around for my problem, I'm starting up my local spring context at application deployment.

Hi Chaminda,
Are you able to resolve this issue now, we are also facing the similar issues.
