1. Re: Drools-jBPM connection
salaboy21 Aug 23, 2011 8:58 AM (in response to tomarenz)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:
http://salaboy.wordpress.com/2011/05/28/emergency-services-v2-jbpm5-and-drools-blueprint/
https://salaboy.wordpress.com/2011/08/12/emergency-services-v3-proposed-features/
source code:
https://github.com/Salaboy/emergency-service-drools-app
Best Regards
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.

2. Re: Drools-jBPM connection
tomarenz Aug 23, 2011 12:31 PM (in response to salaboy21)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

3. Re: Drools-jBPM connection
salaboy21 Aug 23, 2011 2:07 PM (in response to tomarenz)Can you check that this repository is configured:
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:
Doing this you will trust in this repository to download dependencies.
Cheers

4. Re: Drools-jBPM connection
tomarenz Aug 24, 2011 6:10 AM (in response to salaboy21)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/
- 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.

5. Re: Drools-jBPM connection
eaa Aug 24, 2011 6:16 AM (in response to tomarenz)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!

6. Re: Drools-jBPM connection
tomarenz Aug 24, 2011 7:25 AM (in response to eaa)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.

7. Re: Drools-jBPM connection
salaboy21 Aug 24, 2011 8:33 AM (in response to tomarenz)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

8. Re: Drools-jBPM connection
tomarenz Aug 24, 2011 9:06 AM (in response to salaboy21)>>> 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.
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.

Cheers

14. Re: Drools-jBPM connection
saihegde May 17, 2012 10:05 AM (in response to tomarenz)Yes, I did that. I had to make a few changes to get to that point as well. Like with the hornetq artifacts, the one's used in the project are no longer on maven central.
The slickCokeAndCode repo gets tagged as a Gaming site and the artifacts do not come down at my workplace.
