Camunda, Restlet, another datasource, transaction

[sojk...@gmail.com]

Hello,

I have a question on your opinion about developing this project:

1) Restlet framework - runs in servlet container on JBoss
2) Camunda framework - JBoss distribution
3) Second database for bussines data

When I recieve some request from client via REST I complete some task in Camunda engine (for example) and I change bussines data. (Not only in workflow).

This all section I want to have in transaction. When Camunda crash all will be rollback, if work with bussines data crash, make rollback too.

What is the best practise? Use Spring framework and his Transaction Manager? Because I am not able to inject any object in Restlet resource class.

Thank a lot for your opinion.

Best regards
Jiri Sojka

Hi Jiri,

 

Is all of this running inside the same application server or is the Restlet based frontend running inside a different JBoss instance? Maybe a high level architecture diagram would help us to discuss this more efficiently.

 

 

If it is all running inside the same JBoss instance then it is simple. (b-left) The process engine as configured in our distribution integrates with JTA transaction manager. Make sure that your secondary persistence uses JTA well.

If you use different datasources for process engine and secondary persistence you need XA for atomicity. (b-right)

 

Cheers

Daniel Meyer

Hi Daniel,

thank you very much. Everything runs fine. I used JTA Transaction Manager, two XA datasources and it works correct finally!
