Re: [rules-users] How to figure out the recent node(s) in a drools flow ?
Excuse me, I think that I haven't been clear enough.
The drools-bam module doesn't force you to activate the persistence.
That's two differents things in fact.
From what I've understood of the execution mechanism of drools, by
default, it doesn't write anything in any database, so, if you want to have the recent
node state of a flow from oustide the program that executes the flow, you have to write
into a database, I can't figure out any other solutions...
Drools-bam module
creates two really simple tables that's named by default processinstancelog and
nodeinstancelog. So it's really easy to request in those. That's the only way I
can find out for your matter.
By the way drools-bam can be found in the maven jboss repository (version 5.1.0-M1).
If you find out any other solution, please tell me, I'm interested.

Hm,
for the event-listener way I need to have an App up and running to catch those, but what
about an App which will be turned on later, but needs to know the actuall state of the
process. This leaves only the first possibility, to use the persistence mechanism and
check out the database ?
That sounds pretty strange to me, since the mechanism to continue from the actual (last
actual) state of the process must be there already (or is this not possible with the
drools flow ? ) and therefor I was hoping to get direct API-access to this mechanism.
So please, let me know if the DB is the only way to figure out at which recent state
(which nodes are recently active) the process instance is or if there is some API to get
this information directly.
Cheers, Rob.

There are different ways of doing this:
-you can activate the drools-bam module to trace the activities of
your nodes in database -you can add an eventlistener to your process
(session.addEventListener) and by this, you can track which node was
activated etc...
-probably other ways :p

How am I able to figure out at which point (node(s)) the recent
process instance is ?
I was looking hard for some methods in the API, but could not find any.
Cheers, Rob.
