Recover bpmn2.0.XML file of an earlier version of process

[habib1]

For a given process I have multiple versions,I need to recover an earlier version of it , my question is :

it is possible to retrieve the contents of bpmn2.0.XML file for each version ?

Hi,

Each version of process definition is stored in the DB as xml string.
Yes it is possible.
How:
e.g.

    // Fetch the resource
    String resourceName = processDefinitionEntity.getResourceName();
    ResourceEntity resource = commandContext.getResourceEntityManager()
            .findResourceByDeploymentIdAndResourceName(processDefinitionEntity.getDeploymentId(), resourceName);

Regards
Martin

thank you very much, I have a problem here: after the deployment of workflows the column "name_" of the table "act_ge_bytearray" still empty for some workflows , what is the cause of it ?

Depends on how you deploy it. It should have a foreign key to the deployment though.
