Re: [rules-users] Deploy Drools in AS7 as OSGi bundles
Thanks for your candid reply. I'm just diving into OSGi and am experiencing the same WTF. Hopefully, I'll be able to stay on this project for a bit and actually get somewhere, but it doesn't look good right now. Good news... GE Healthcare may be opening the door and allowing us to participate in the Open Source community. If that happens, I may be able to pitch in.

Re: [rules-users] Protobuf Marshaller Question (ScheduledActivation Persistence)
Thanks Edson for your reply. I am really looking forward to work on a solution for this. What you write also makes absolutely sense to me. As far as I can see, the ScheduledActivation is unmarshalled correctly to the Agenda. Moreover, after unmarshalling the agenda my logger says that there is one active and one scheduled activation (interestingly, the agendaSize equals zero, but anyway). logger.info(agenda size: +agenda.agendaSize()); logger.info(activations: +agenda.getActivations().length); logger.info(scheduledActivations: +agenda.getScheduledActivations().length); logger.info(activeActivations: +agenda.getActiveActivations() ); logger.info(dormantActivations: +agenda.getDormantActivations()); Since the ProtobufOutputMarshaller seems to use the scheduled job instances (Timers _timers = writeTimers( context.wm.getTimerService().getTimerJobInstances(), context ); I tried to look what's in these list. However, in all cases the list of job instances is empty. logger.info(timer service2: +((StatefulKnowledgeSessionImpl) this.session).getTimerService()); logger.info(timer service2: +((StatefulKnowledgeSessionImpl) this.session).getTimerService().getTimerJobInstances()); logger.info(timer service wm: +((InternalWorkingMemory) ((StatefulKnowledgeSessionImpl) this.session).session).getTimerService()); logger.info(timer service wm: +((InternalWorkingMemory) ((StatefulKnowledgeSessionImpl) this.session).session).getTimerService().getTimerJobInstances()); As suggested by you, I simply switched to the current 5.5.0.Beta1 deps from nexus (because I don't know where I can get the branch builds from beyond version 5.4.0.Final). However, a quick test run tells me that the problem persists. Therefore, I'm gonna write a self-contained test and file a JIRA accordingly. I keep you updated. Thanks a lot, Philipp 2012/10/1 Edson Tirelli ed.tire...@gmail.com: Phillip, Thanks for investigating this. There are few developers that know this area of the code, and so it is indeed a bit hard to get extra information. Here is a quick recap: although the serialization change on Drools 5.3 involved a move to use protobuf as the serialization framework, Protobuf is nothing more than a way to easily handle the actual data persistence. The whole logic is one layer up in the scale and there is where the investigation should focus. So, lets forget Protobuf for the moment. Before 5.3, we used to serialize all the data structures and intermediate data inside a session using custom data structures. That was a big problem because, for instance, if a session was serialized with one version of Drools, and then someone tried to use any other version of Drools to deserialize the session, it would not work. Even a simple bug fix could affect the internal data structures and make a session impossible to deserialize. To avoid that, from 5.3 and forward, we no longer serialize everything, but instead we serialize only the necessary raw data that allows us to reconstruct a session. To be more clear, lets imagine that we have a session and a fact A1 in there, and an activation of rule R1 for fact A1. When the session is serialized, we will basically serialize fact A1 and a record that R1 was active for fact A1. When we deserialize the session, we will re-propagate A1 through the engine, recreating all the data structures and then correlate the new activation of R1 with the serialized activation of R1. Having said that, even scheduled activations should be properly serialized/deserialized. I think there was a bug fixed related to timer serialization, so the first thing I would like to suggest is to check your use case against the 5.4.x branch where fixed bugs are committed. If you still see the problem there, then please open a JIRA with a self-contained test showing the problem, and I will take a look as soon as I can.

However, I found another issue that seems to be related.

One of the rules:
rule 'BP - HOMULTIPLE'
agenda-group user-rules

when
COUNT(BP_HOCONDITION) = 2
then

Expanded rule should be something like this:

then

Too many of our dependencies do not have real OSGi bundles available, so we have to resort to the spring repository - where the versions almost never match our original target version. Further when it fails it's almost freaking impossible to determine why it fails. The problem with the spring enterprise bundle repository, is that spring source is no longer actively interested in OSGi (ever since they donated spring-dm to the eclipse foundation) and a lot of the bundles they provide are either out of date, or just say not optimal. A much shorter repository but with better maintained bundles is the repository of service-mix bundles: http://repo1.maven.org/maven2/org/apache/servicemix/bundles/ which host bundles for service-mix, camel etc. Of course, bundles and metadata are always one side of the problem. Usually, the use of class loaders requires some treatment too. I'd like to contribute too, in providing a better OSGi support and maybe add some integration tests using pax-exam or arquillian. -- *Ioannis Canellos* / /*/ /Blog: http://iocanel.blogspot.com http://iocanel.blogspot.com// /*/ Twitter: iocanel / ___ rules-users mailing list rules-users@lists.jboss.org https://lists.jboss.org/mailman/listinfo/rules-users ___ rules-users mailing list rules-users@lists.jboss.org https://lists.jboss.org/mailman/listinfo/rules-users
[rules-users] droolsjbpm-build-bootstrap script is broken ?

[rules-users] Drools and Weld dependency ?
Hi, I'm trying to use JBPM 5.4-SNAPSHOT and Drools 5.5-SNAPSHOT in a OSGi env. drools-compiler's generated manifest has a import package to org.jboss.weld.environment.se.discovery.url. Could someone explain me what is this new dependency ? Weld is really mandatory to drools 5.5 ? thanks, Cristiano ___ rules-users mailing list rules-users@lists.jboss.org https://lists.jboss.org/mailman/listinfo/rules-users

[rules-users] Checking Template Columns matching with Excel columns
Hi, I am using drools template and spredsheet in my application. my generic rules are maintain in template and rules data are maintained in spreadsheet. Currently i am declaring the columns name in my template file for using the field of excel. ex: Inside template (drt) template header rulesName Application Admission Permission . . . . inside excel rule(col 1), application(col2),admission(col3), permission(col4), . . . . . i want to make sure the excel col name has to match with exact name inside template. currently drools checks the order of the col declared in template with excel columns but not the actual name with the excel columns. Any possibility by which i can force drools to match the exact col name with the col name defined inside template file? Thanks... - Thanks...
