Newbie question : Process Instances

[viniciuscarvalho]

Hello there! I've just started with jBPM, I'm reading the docs and checking the forums, but I have an immediate question that I need to feedback my project stakeholder: Does jBPM supports multiple applications accessing the same project instance? I mean, could I have several web apps sharing the same project instance (most of them will be created with Seam)?

Regards

pocessinstance you mean... yes, although afaik, jbpm uses pessimistic locking...

Thanks for your reply. Sorry for the typo :P
Well pessimist locking should not be an issue, we are more interested in long term process, not so much on concurrency. The cool thing we need is to have two applications (say check-in and billing) having access to the same process

Best regards

no problem. You can use jbpm this way. just make sure you have one jbpm instance that you access remotely or install jbpm with each application (jbpm core is 'just' a library) and point to the same database. When using multiple jbpm instances, make sure only one runs the scheduler
