Hello Activti Experts,I am building a new web application. This includes a moderate complex workflow where multiple user approvals are required with different user roles (project specific).Workflow Scenario is like:1) There is a Approval Sequence (Parent) where there are N Approval Stages required.2

1) Activiti and Spring are best friends, they even sit together at lunch time No seriously… You can use existing spring-beans in expressions in your process, this makes it easy to use a spring-bean as a delegate (<serviceTask id="serviceTask" activiti:delegateExpression="${delegateExpressionBean}" />) or call methods on spring-beans from within the process (

<serviceTask id="javaService"  name="My Java Service Task" activiti:expression="#{printer.printMessage(execution, myVar)}" />

).

2) The process you're describing is a perfect fit for activiti and would take more time if you would write your own state-machine for this…
3) Since you're using spring, activity makes use of the PlatformTransactionManager, so any changes done in your services/model can participate in the same transaction as activiti does, without any hassle. We also have a pluggable variable-mechanism to allow to use your domain-model in the process-context (as variables) without storing duplicate data in activiti, but only pointers to your objects. We have a JPA-integration as an example of this shipped OOTB.

4) That's up to you. We offer an API to do everything you want with processes - management, runtime, history, … - so your services/UI should consume the API, adding some additional logic, specific for your use cases on top of our API.

Hi,

Please provide more details about your question, because it's very difficult to answer it now.

Best regards,
