Hi,I have an Activiti process defined with one serviceTask followed by one subProcess. As I understand, when multiple users perform this process, Acitviti will create a new thread for each user request to execute the process. My issue is that I can have the serviceTask executed concurrently for each

Looking for a solution to handle it declaratively in XML itself if possible.

Hi Gurpreet,

I would suggest to:
1. make subprocess asynchronous
2. Change jobExecutor to execute this subprocess sequentially.

Martin

Thanks Martin for your response.

Since I am fairly new to Activiti, can you please elaborate on point#2 i.e. how it can be achieved?

Regards

Gurpreet

Hi Gurpreet,

1. make subprocess asynchronous

just change your process model.

2. Change jobExecutor to execute this subprocess sequentially.

You have to re-implement Default job executor to execute given subprocesses in one thread only. (I did not find an example in the source code - you have to debug current implementation little bit)
