Activiti deployment

Situation:I have multiple web applications(lets call them client applications) that need to manage a set of processes(intersecting). From what I have gathered, best course of action (correct me if i am wrong) is to deploy activiti engine standalone (lets call it server application)and drive activit

Another option is always to include the Java jar in all web applications. It simplies stuff sometimes.

1) Activiti Rest will give you the default Activiti REST API. You can create your own REST API application if you want to, by included the REST dependencies. I'm not sure i'm following your process development question. This would be similar to how you would solve a shared code project in your company.

Q1) Processes are just xml and could go into Git or svn. Once you deem one ready for production, you deploy that xml.

Q2) No. You can deploy one at the time.

Q3) Process definitions are versioned on deployment. Instances keep running against a particular process definition version. New instances will follow the new process definition.

Q4) check the activiti-rest and activiti-webapp-rest maven modules. We are using Spring MVC. You can create your own version of that; with custom REST endpoints or just go with the default.

Hello Joram, thank you for your response.
I was not talking about how I can share process definitions with team members. Assume at iteration n, I have 10 processes. At iteration n+1, a team member updated 1 process definition(pd) and deleted 1 pd and added 1 pd. If this have been a database change, I would want the change propagate through dev, test, and prod environments without manual intervention (for example by orm or db migration tool). But from your response, I understand that I have to check change dates of process definition files against the date of previous iteration, and upload to server application manually. Am I correct?

Process definitions are 'deployed' in Activiti through the API, which writes it to the database. So you could do it automatically over all your environments, but that's not part of Activiti, it would need to be custom logic.

Is there a possibility that I could actually update my previous activiti deployment? What I mean is, when you deploy a bpmn, it is given a deployment id as evident in act_re_deployment table but I want to know if that id given to the previous deployment could be used as an id of the new deployment since I am deploying the same bpmn file but the latter file have additional user tasks (for approval purposes)…

No. Activiti always deploys a new version. See my answer on your other post.
