Since activiti has first class Spring-support, it's just a matter of configuring activiti in your app's spring-context and wiring in the datasource.

Thanks Fred. agree with you. I am using spring integration to fetch handle to process engine in my application.

I am trying to wrap activiti services (runtime,task…) inside my Workflowservice.My application code will access activiti services via WorkFlowService instead of direct access to activiti services.

The next question is related to end-end integration. On UI user will see my app form..after storing the information to database, I need to make call to the activiti to start the process instance. After that need to call activiti for tasks list and show it to the user. There will be some redundancy of data.. data in app db and data in activiti db. Also there is need to keep both data in sync. Any suggestions here..

The best approach is NOT to have redundancy in data and only store references in the Activiti DB.
Whenever you need the real data, use the reference to look up the 'real' data through some dedicated service.
