"Drools-jBPM connection"

--------------------------------------------------------------
Hi all,
I'm trying to get an overview concerning any relation between Drools and jBPM, e.g.
how business rules can drive a process flow.
Till now I understood that rules enter the game as:
- conditions to constrain choices in xor xplit gateways.
- business rule tasks (I guess there is an embedded workItemHandler somewhere).
- anything else ?
However I miss how facts are managed, e.g. how process tasks declare facts to be used
later on by rules in the same process and how scopes are defined.
Is there any document/tutorial/example explaining how these two worlds interconnect ?
Thanks.

Hi renzo,
There is a whole new world behind running the processes and rules together in the same
runtime (and don't forget events). Running rules and processes you can model and
implement very complex scenarios that requires the execution of ordered activities as
proposed by business processes and more unstructured activities and business logic using
business rules. Combining them both you can drive business processes using business rules
or orchestrate your business logic using as you mention business rule tasks and
conditions. But you can also trigger new business processes, sub processes, dynamic
branches, deal with expcetional situations, etc with business rules more easily, without
complicating the process graph.
If you include events to the mix you can also model more dynamic aspects of your
applications, like live streams of information that is coming from different sources and
you need to evaluate, aggregate and correlate that information with your process status
and your facts information in order to react in near real time.
I strongly suggest you to take a look at the emergency services application that we are
developing to show how to architect and model complex scenarios using these technologies:

PS: we are currently working on the version 3 of the application, so I think its a very
good opportunity to help us an learn in the process.

Thanks Mauricio, the overall picture is challenging.
Btw, I tried to install v2 sources to have all in Eclipse.
Maven complains about 2 missing artifacts it could not download from any configured
repository:
1) com.wordpress.salaboy.smarttasks:smart-tasks-api:jar:1.0-SNAPSHOT
2) com.wordpress.salaboy.smarttasks:smart-tasks-jbpm5-impl:jar:1.0-SNAPSHOT

Can you check that this repository is configured:
https://repository-plugtree-org.forge.cloudbees.com/snapshot/
https://repository-plugtree-org.forge.cloudbees.com/snapshot/
If so, you should register that repository in your CACERTS certificates, for doing that
you can follow this steps:
https://cloudbees.zendesk.com/entries/20078393-configuring-maven-to-acces...
https://cloudbees.zendesk.com/entries/20078393-configuring-maven-to-acces...
Doing this you will trust in this repository to download dependencies.
Cheers

Thanks, but I still have the same issue, also because the above url instructions conflict
with README instructions:
- I'm using win7 64 bits and jdk 1.6.0_27
- I got the certificate from
https://repository-plugtree-org.forge.cloudbees.com/snapshot/
https://repository-plugtree-org.forge.cloudbees.com/snapshot/
- I imported it into "\Program Files\java\jdk1.6.0_27\jre\lib\security\cacerts jdk
keystore.
However:
- this keystore needs a password to retrieve the certificate, I wonder how maven manages
it. The same about any assigned alias name.
- the above repository wants a login with password, I wonder how I can get it and tell
maven about.

I think Plugtree's maven repo is having some technical problems right now. The
repository shouldn't require any username/password. We will try to fix them asap!

Well, in the mean time I wanted to have a look at process diagrams
(emergency-service-core), by opening them in Eclipse (Indigo 3.7, where jBPM diagrams are
usually ok).
None succeeded, throwing:

Unfortunately no way even from the designer (in Drools-Guvnor), since the only way I know
of to import into Guvnor is from Eclipse.

Hi Renzo,
The keystore password is the default one: "changeit"
The repositories are now ok and working.If you manage to get the keystore registered in
the jdk certificates it should work, because you don't want to change anything in the
repos, maven will only check and download artifacts from there.
About guvnor and eclipse, all the processes are being displayed here, make sure that you
have the latest plugin version, the model project also in your workspace (inside the
processes we are using classes from the model project) and the latests drools & jbpm5
runtime configured inside eclipse.
Cheers

>> The repositories are now ok and working. <<<
I still get an authentication request:
A user name and password are being requested by
https://repository-plugtree-org.forge.cloudbees.com
https://repository-plugtree-org.forge.cloudbees.com.
The site says: "plugtree-org repository"
Btw I use FF 5.01, but IE8 does the same.
About Guvnor and Eclipse: I installed jBPM 5.1.0 final and I tried to open process
definitions as single .bpmn files (no java), since I have no projects until the missing
artifact issue is solved.

Today there is no login request, so that dowloading from Plugtree succeeds.
However no Eclipse projects are generated. One test fails as:
