For using Activiti you must create a processEngine, for example
ProcessEngine pe = ProcessEngineConfiguration .createProcessEngineConfigurationFromResourceDefault() .buildProcessEngine();
The documentation advice is to avoid to parse more than once the BPMN Xml because it's costly. They say to store ini a static field of external JNDI. So is it possible to store the processEngine instance reference (here
pe
) in a database (as a blob probably), and getting it again in a complete different execution context ? Before doing it myself I'd like to know if this is pertinent.
What do you mean ? The matter is to know if it's better (in terms of executing time) to re-parse the BPMN XML file every time you need it, or it's better to store the processEngine instance somewhere else. The documentation seems to say that. Thank you for your answer.
store engine in the DB - after the fetch you have to reestablish all DB connections, beans…. , I think that's the time consuming part of process engine initialization.
