Activiti 5.13 with Spring Java config

[sriramks]

Hi,

I am new to Activiti Engine

My Project setup is

1. Spring MVC
2. Spring Ioc
3. Spring Security
4. Activiti Engine
5. JPA

The configuration in use is Java based configuration

I'm assuming your 'leaveTypeServiceImpl' bean needs to be a real bean in Spring, now you are passing it to the engine config, but it is now knows as a Spring managed bean.
