jBPM 6 Create own persistence

[marinav]

Hello Community,

I am new to jBPM and try to integrate jBPM 6 in an existing CRM Application. To resume the processes after a server crash, I have to create a persistence mechanism. The CRM Application already has a persistence mechanism with spring and hibernate and I would like to use this mechanism to save the jBPM specific data. Moreover, I need to persist some extra data.

My question now is: Is there a way to create your own persistence for jBPM and reload the session and resume the processes manually?

Thank you very much

Hello,

To specify my question: Is it possible to trigger a special node in a process without executing the nodes before?

How is it realised in the jBPM Persistence that the processes are resumed from the last wait state instead of restart the whole process?

Thank you.

take a look at documentation regarding persistence. That will give you quite clear picture of what is stored, how and when.

you could use ad hoc processes that allows you to signal node that are not in structured flow - like standalone node or process fragments. See flexible processes section in the docs.

Hi Maciej,

Thanks for your reply.

I read the documentation about the persistence and came to the conclusion, that it is too complex to implement an own persistence mechanism. You have to take care of too many things, like for example the parameters a process instance has, or the current node which is excetued. And it is really complex to restart a process at a special node.

If someone ever implemented an own persistence mechanism for jBPM, I would be interested in seeing your implementation.

For the moment i better try to use the already existing persistence by jBPM.
