Does Activiti Engine use thread pooling?

[alper]

I see only 1 thread of Activity in the VisualVM.
So the question is: does Activiti Engine use thread pooling, or new thread is created each time it is needed?
If it creates new thread each time, then it should be slow and heavy operation…
Could developers answer this question?

Thank you

YEs, it does. You might have forgotten to start the job executor.

Nice, thank you, is there any example how to use it?

I didn't forget to activate it, my code is:

<java>
processEngine = ProcessEngineConfiguration
    .createStandaloneInMemProcessEngineConfiguration()
    .setDatabaseSchemaUpdate(
      ProcessEngineConfiguration.DB_SCHEMA_UPDATE_TRUE)
    .setDataSourceJndiName("java:jboss/datasources/ActivitiDS")
    .setJobExecutorActivate(true).buildProcessEngine();
</java>

Another question: how configurate it? or I should hard-code all parameters and re-build the engine jar?

No, you can get the instances through the ProcessEngineConfiguration (or processEngineConfigurationImpl after a cast)
