[Design of JBoss jBPM] - Re: interested in contributing ?

by caleb.powell

Hi, I just wanted to let you know that I have made a request to open source the jbpm-migrator project. It may take a little while to get an answer, as we are currently in the middle of kicking of some new development work. I will let you know as soon as I have some news.

[Design of JBoss jBPM] - Re: Is it possible to avoid hibernate?

by tom.baeyens＠jboss.com

yes. that all makees sense. let's start with trying to get as much as possible of jbpm to run in memory mode through the normal service based api. still remains to be seen how well the current implementation already supports this strategy. if all we need is some memory implementations of the some sessions and small patches here and there to head to make this work then i want to include those patches very much. theoretically the design should support it...

[Design of JBoss jBPM] - current activity of execution

by camunda

Hi. To query the current activity of an execution I have to cast the ProcessInstance to the ExecutionImpl class: | ((org.jbpm.pvm.internal.model.ExecutionImpl)pi).getActivityName(); | because it is not part of the PVM/API. Or did I miss something? Why is that the case, an activity name should be available for every language, hence be part of the API, or not?

I agree with Camunda that an API should be the way. This way you only have to configure the cfg.xml file with services you want, mode you want, implementatiosn for the service, and client code wouldn't need to change much. If you use ExecutionService, this service should be used for any kind of execution. The difference could be to have o not to have a HistoryService, for example.

And have a in memory implementation which just keeps references of running instances? But it is not easy to build, I agree...

implementing the repository service on top of the classpath resources is another option. it's less flexible, but indeed much more achievable. so it is a good path to try out as well.

[Design of JBoss jBPM] - Re: Is it possible to avoid hibernate?

by jorgemoralespou_2

What I'm thinking of is, to build my own custom ProcessRepository. This process repository would be held in memory, as I only want latest process definitions to be used. Then I would like to instantiate different ExecutionServices, with different persistent strategies for executions and history (memory, db) to enable asynchronous process executions (persistent mode) and synchronous process execution. (memory execution, and persistent or without history). I'll try to start with the on memory process repository, trying to hold ProcessDefinitions in Memory. And then, I think IÄºl try to configure an ExecutionService, without history. Any thoughts?

with the jbpm core, it should be possible to build out all execution modes as described in http://www.jboss.org/community/wiki/jBPM4ExecutionModes i believe that you are referring to the 'Memory' execution mode, right ? the direction we're thinking in for that use case is to use the ProcessBuilder to create process definitions. Probably we can leverage the JpdlParser for that as wel. That will immediately give most of jPDL features instead of having to start from an empty PVM. Maybe some dependencies on the environment configuration sneeked in here or there. Our current idea is to use methods on the objects themselves for the memory execution mode, and skip the services api's It would be great if you could try that direction and see where you run into problems.

Is there any kind of design docs. I'm eager to collaborate with this task, but I don't want to work in a diverging direction.
